Guidelines

okay uh really delighted to meet you all um and happy New Year hope uh this will turn out to be a wonderful year for all of you so this is a course to be taken by both third year students and fourth year students right um can all the third year students raise your hands okay Okay I uh my eyesight is not very good so I'm going to ask the fourth Years also fourth years yeah thanks thank you so this course is uh considered very important by the department that is why it said that it will continue as it is for the third years even though many courses got changed merged and so on this course will remain more or less the same uh except for for one small change which I will point out as we go along it is also the culmination course that means you learn a lot of things in the in the curriculum and then the proof of the pudding is in building a plant which is what you're going to do in this course right as a matter of fact we asked uh all of you whether you you would like to work on any specific chemical in the fourth year batch uh there were four groups that said that they wanted to work on a chemical of their choice okay we assigned the reason being that um uh we had um our Alum prep jaura I think he graduated in 73 if I'm not mistaken 72 or 73 he wanted to work on a particular chemical in a similar course and uh he took the head's permission he worked on it afterwards he went on to establish the same plant and he is a successful entrepreneur as a matter of fact he has set up an award for this course for the project that does well so we will I assume that we will do that one for uh fourth years and one for third years and uh I strongly believe in fact many of my colleagues share this that it is possible uh to uh have some entrepreneurs out of you who will go into the core sector I'm sure that there will be some of you who will have some it internet and you know so on and and so forth but it is the core sector in which you know you'll be the you know most competent person compared to possibly anybody else okay and uh we believe that um such a thing will happen and this course uh could be the first step in that direction and in case any of you would want to do that the department will be more than happy to uh support all of you uh so the way we are going to do that is uh this lecture is um uh I'm going to give a overview of how this course will be run then we have Prof Sanjay mahajani he will give a um short presentation and uh we have Professor Rahul naar you all know him he teaches the Fine Chemicals course how many of you have registered for that course okay okay it's better to ask how many of you have not registered almost everybody seems to have raised your hand okay so he's our uh star batsman he's going to do it afterwards and then Professor yra shastri will come and talk um he will talk about um um you know uh sustainability and carbon footprint and you know some of these things okay so these are some of the references that will be used okay and here is um a Texas andm University uh they have given a link so we thought that many of the references in that will be useful so I given the link for that also I want to show you the weekly schedule it's a very very tight course it is not possible to uh postpone any lecture it is not possible to cancel any lecture because we cannot make up for that okay so there is a weekly schedule which I will uh show uh we will put the weekly schedule also on the model so we have shown uh CL 331 and cl 452 separately in case uh there are going to be any differences because of your uh you know previous courses and you know things like that but let me open this CL 452 weekly U schedule so we have um uh the first week on the date is given 14th January 17th January so we will have this class on Tuesdays and Fridays Tuesday afternoon and Friday afternoon and uh in every um class so whatever I'm saying is going to be applicable to the third years as well as the fourth years the class will be divided into two halves one half will do the work and the other half will make the presentation so in other words um so you will have uh PR water this called a b uh you will have two divisions A and B in each class so division a will make presentation and division B will do the work for their presentation on the next class right that division B who does the word they are not presenting they will be here so in this class this is the classroom for both third years and the fourth years who are doing the actual work okay who are not presenting they'll come here and we'll have two Tas here and those who are presenting will be divided into three panels there are going to be two faculty members in charge of each of the panels and uh so we have some of the faculty members here and as you can see the department has uh assigned 12 faculty members to teach this course um six for 331 and six for U 452 each will have three panels okay so it's an important course that's why the department said that they will assign six uh 12 faculty members to teach this course now uh so we'll have um so this written as division a and division B division a will start presenting 14th January and then 17th January division B will make presentation and what they are supposed to do is given here explained as the task literature review and background work then detailed uh flow sheet development here uh I call it as mass balance mass balance means uh you will have to say something like I have this column I expect this kind of split or I have the reactor I expect this amount of conver conversion so you will put that put those numbers and based on that you'll be able to do the mass balance it is not based on detailed calculation rather it is not based on a simulator work simulator is going to come later right you will have to say that this is what I want from this or this is what I see in the patent in the patent they say that I will get a 9010 split so you put that so you'll be able to do a mass balance using that information right similarly for reactor separator so on and so forth mixer whatever you have right so you have to do that kind of mass balance here after that comes steady state St uh flow sheet simulation uh the fourth year students have already been exposed to DW Sim so you may find it convenient to use DW Sim if some of you want to use some other Simulator for whatever reason it's okay for example you might say thermodynamics is better or that property is present in uh Aspen plus but not in DW Sim I'm going to use some other simulator that is okay or some of you might say that I have a difficulty in convergence maybe Asen plus has better model people have reported that there is a problem of course it is possible that if you don't try hard enough it may not converge in which case it it will be a waste of time to shift to a new simulator you would rather make sure you put in the effort in the old simulator and make it work right the third year students have not had a course in DW Sim and um the department said that let them learn dwsim as a part of this course all right otherwise you won't have fourth year free to do whatever you want right that's what you wanted right we wanted to release the free time for you so what we are going to do is by the way dwsim learning is extremely simple and you can learn without any problem and for you for the CL 331 students stents on Friday in this very classroom PRI and his team will conduct a workshop on DW Sim okay so all of you come over and those of you even four five2 students in case anybody wants to be here you're welcome um dwc will be covered and we have learning material through what is known as spoken tutorial which is created for self- Learning and uh so you can figure it out yourself right it's not a it's uh it's very easy I know that you can figure out all new things and DW Sim is no exception right so in this um one of the things that you would also do in this week in week four yeah week four week four of course the dates are given here one of the things that you have to do is you have to compare compare the results obtained from mass balance and simulation and justify the difference remember you did a linear we called it linear mass balance here right perform linear mass balance so you got some values you said I want this split I want this conversion I want this Purity accordingly you came up with a mass balance okay how to arrive at that how did you get that you got it from a reference uh literature uh uh Journal article patent or whatever it is so you put those numbers right so without asking without doing a detailed study of how you are going to get it okay so you have the mass balance energy balance you don't do only mass balance okay but when you go to the steady state flow flow sheet simulation using whatever simulator you are going to use you will do the simulation and then you will compare the results obtained from mass balance and simulation and you have to justify the difference okay so in other words the the steady state simulation the flow sheet based simulation is done to arrive at the splits convergence conversion so on and so forth right that's what this is for then after that you will do parametric study of operating parameters so in this um can you suggest some parameters that you want you would want to uh you want to study can you think of any parameters whose sensitivity you would want to find name some parameters anyone a reactor for example okay so you can think of it as a residence time for example right you can think of it as a Rea temperature feed temperature right you can think of as um um maybe whether it is arotic or operating temperature one is of course Fe temperature the operating temperature so on and so forth you may want to perturb some of these things so that it will tell you for some in some range there is no change at all then it allows you to choose a particular value that is that makes economical sense or sense makes sense from safety point of view and so on right what about a distillation column what do you think reboiler Duty okay so reboiler duty means you will you may say I want to change the purity right in some cases it may be possible some cases if it allows you if it if you can operate in a band then it is okay you can do that okay anything else ah this is what I wanted to hear so reflex ratio is supposing supposing you say that I'm going to do 10 times the minimum reflex ratio will the Purity get better it might right so is there a consequence if you use a very large reflex ratio what will happen let's have the product reboiler Duty what did that person say what will happen to reboiler duty reboiler duty will also increase because you have to reflex you're sending lot of things below and then you have to heat it right so you may say I'm going to get .1% Improvement but your energy cost is going to shoot up so please do not so which means you actually don't have any freedom in working with reflex ratio most of the time the simulator will give you simulator will say I can do a sensitivity study of the distillation column using reflex ratio but please don't do that because if you do that it will say put very large reflex ratio because you will get better Purity but you will go bankrupt right you'll go bankrupt because truly speaking if you want to see the effect you should include the energy cost also but then you may not have done the costing by that time so it's not possible to do that so it is better to stay away from the reflex ratio please all of you remember if anybody perts The Reflex ratio I'm going to flunk you okay anybody comes up with reflex ratio and say I'm going to use 10 times The Reflex ratio and do such uh uh you know meaningless simulation studies you will get at least one grade less if not getting flued is that okay is that clear why you should not use reflex ratio as a sensitiv as a parameter of parameter for sensitivity studies okay so here you see uh look at line number 10 it says evaluation stage one here you will submit a report you have to submit a report until this time so this says on 28th January on 31st January on that day you will submit a report and there will also be a presentation okay and then you have U steady state flow sheet simulation parametric study of operating parameters and then in the in this um week stage two report will be submitted and uh there is nothing additional here but you will complete the specific tasks given by The Faculty panel faculty panel will say do this do that or some of the things you may not have done this week is given to catch up right and after 21st February you're going to come back only on 7th of March why is that mid semester exam and uh uh in fact the mid semester exam will start immediately right in fact all of the next week we could have started on the next Monday itself but then the students will come and say I didn't have time to prepare right so we are we are giving the Monday off so that you have time to prepare so the next presentation will be on 7th March Friday is that clear then it shift then division B comes first and division a comes next okay why is that because in the past division B students have complained uh sorry division a students have complained I have an advantage disadvantage because I'm presenting first so we are going to make them present second after mid semester is that okay so equipment sizing of all equipment economics uh profor Sanjay maaj has has quite a few things to talk about about economics uh detailed design of one equipment that you have to do and then the date is given evaluation stage three then we have environmental uh impact assessment report submission and final presentation and then we have final valuation uh so your classes will uh end on 11th April what we might do we did this last year we might do it this year also we might select one or two um groups maybe two groups from each panel and uh we will forward them to the industry industry assessment and select the top two last year we actually had the industry people coming and looking at all six remember we are going to select best two from each of the three panels and they will go through it and select the top two last year we had a presentation by these six groups to the industry uh experts I'm not sure whether we are going to do it this this time or not because we have to do it for two years and I I don't know whether we have slots okay but we will play it by the year we might still do that but assessment by the industry that we will try to do and that is where the any question on this whatever we discussed just now okay so that was weekly schedule grading pattern okay let me show that so here are the breakup of marks weekly tasks 30% okay weekly task means whatever you are going to present and then evaluation so this means this is only for presentation right PR weekly tasks evaluation stage one 10% this is for the report report and vaa okay so evaluation stage one 2 three and four four we call it final evaluation those marks are separate both presentation and vaa both presentation and the report okay by the way presentation means it is vaa also because we will ask you questions and um uh you know we can have discussion on how the presentation will be made and how we will assess you and so on we can uh talk about it later but the weeks in which you are going to submit the reports will be referred to as evaluation stage 1 2 3 and final evaluation stage okay those together will carry 70% marks all other weeks presentations will carry 30% is that okay and the evaluation stage breakup vaa will carry 60% and report will carry 40% the report will have common Mark for everybody but vaa will have different marks depending on how you present have you whether you have uh done the work not not done the work okay whether you are able to answer the questions and so on and so forth based on that we will give 60% of this which means evaluation stage one six marks will be for vaa four marks will be for the report is it okay 60% of this 10% uh report will be 40% of this 10% stage two and three it will be 60% of 15% and so on uh by the way all the files everything that I'm showing will be uploaded on mood so in case you missed out something don't worry it'll be there um so during the weekly tasks a soft copy of the presentation should be uploaded onto Moodle by 11:00 a.m. on the day of the presentation okay all the presentation should be uploaded onto Moodle by 11:00 a.m. onto the Moodle and that's what will be used and if there is any um late this thing there will be a penalty and uh and it will be that presentation which you will use for presenting you cannot say I made a mistake I have a corrected one will not permit you you better put it by 11:00 a.m. and use that so in other words you do everything ahead of time we don't have time to do all these things it it has to it has to this course has to go as a Clockwork okay we will do a plagiarism check on every report and institute's Norms will be followed in case of any plagiarism extremely important extremely important okay heads of many important people have rolled because they plagiarized or there was a suggestion so we are no exception right so we will use the plagiarism check software that IIT has enabled the plagiarism index has to be less than 20% if it exceeds 20% by x% there will be a penalty of 5x % up to 40% similarity okay so in other words if there is an index of 25% that extra 5% Time 5 so 25% penalty will be applied okay Beyond 40% similarity the report will not even be accepted it will be rejected okay please take the plagiarism extremely seriously next one one of the things people have the habit of copying all kinds of figures unnecessary things you do a literature search some figure came beautiful looking fig figure copy paste it so up to 45 figures can be copied from other sources provided that the source is acknowledged for any figure Beyond this there will be a penalty of 5% for each figure we don't want you to do that you redraw it okay don't put unnecessary figures don't clutter the thing don't make it look jassy with lots of beautiful looking color pictures we are going to penalize if you do it if you w do it we have Tas every panel will have one ta there are six panels for two courses and there will be two Tas here okay they'll also be available for any um Makeup Session and so on as I already told you there will be a dwc workshop for cl 331 on Friday 10th January 2025 in this Hall okay uh report writing Professor sandip R suggested that can we use Google doc so we are we said that it'll be okay um we will use Google do Google doc create a folder for every group and um separate PDF for each stage so that we know what you submitted we know what we looked at in the previous one and of course um you have to submit two physical copies of the report uh by the way this report submission comes four times okay and there is only one copy U you don't have to have there might be six uh people in a group you don't have to submit six copies uh only one copy actually two copies are required one for each examiner there are two examiners in each panel so you have to submit but the Google Doc person say will be only one you it will evolve okay so that will allow that the same Google doc same report is you can look at it at various stages okay is that okay are you comfortable using Google doc for writing the report okay in case somebody doesn't want to do it you would rather use lattic you're welcome okay okay this is an important thing a few years ago I think it was 2020 uh there was a group that found that their chemical was studied in reasonable detail and that a report was already available some European University what the group did was they took it and submitted in stages okay but uh you know some of us have also undergone education like you in institutions like yours right so it was a serious problem we C and they got F okay it was a fourth year batch so it was a problem for them so if such a thing happens what we want you to do is please report it please report it so that you don't get into difficulty it also makes our work totally unpleasant do you think we like enjoy we enjoy giving F we have sleepless nights if you have to give F right it may be possible that we might might allow you to use that we might say okay that chemical is okay good that somebody has done let's add to that it may be possible that's what I meant by reported add to it for example you might say that okay they have done it in this through this route I'm going to take some other roote I'll produce the same chemical it's fine and compare contrast maybe from let's say carbon footprint point of view it may be a lot better the new one that you propose for example right you may want to do p and I diagram for example you may want to do a detailed design of more units because we have in one week you are supposed to do a detailed design of one of the units here you might say do do a detailed design of the whole thing right or you might say that let me do a dynamic simulation of a critical unit there are any possibilities I'm not I'm just giving an example or you might say that I don't want to do this chemical it has already been done Please assign some other chemical that's also fine okay but please don't do that plagiarism you'll get into big trouble Big Time trouble don't want to do that is that okay another thing you'll find kinetics may not be available so Prof Sanjay vajani will help come up with similar chemicals that have the required Property Data okay what if thermodynamics are not available group contribution method Professor sandip Ray will help or other thermodynamics faculty members here will help simulation report simulation support we have professor professor Malik one of the I would say outstanding experts on this topic in the country he'll be here he retired but I have requested him to be with us on Tuesdays on Fridays by the way that's one reason why we kept them together the third year and fourth year together I cannot expect Professor Malik to come from here T four times a week so now he has to come only twice a week he'll be here all your simulation doubts and so on he'll be here to help we will have some uh meetings by industry experts to be organized by I mean our own uh people Professor Rahul nabar may give some talks Sanjay mahini may give some talks um they may also bring in some experts Professor guru's classmates some of them are entrepreneurs he may bring some of them some of the alumni are um extremely passionate about this in fact last year we had one I think 1972 Alum he came and gave a talk and um and you you should listen to them talk and uh you know you feel as if you'll feel that you know this is what made their life I mean designing the plant I mean it's incredible the kind of um enthusiasm they can uh they can transfer to you possibly we should have one some of those courses right in the beginning so that will probably motivate our students so 4:30 p.m. uh Wednesday we will have that so all your questions please ask it will be an optional um uh meeting and um uh the venue has to be identified so we'll have to find a classroom where we can do this so we have some guidelines uh on how the report should be created and so on and the presentation so this is one guideline that uh um we implemented and uh it's very good whenever you make a presentation from the second presentation onwards please find out this point out the suggestions made in the previous presentation you presented the examiners told you do this do this do this make make a note of it and the when next time when you come you say these are the suggestions made and then explain how you attended to them do this as I mentioned earlier at the beginning of every presentation and then go on to the new work that you did okay so that will make it very clear so there is a continuity of what we suggested and what you did next we take up capacity of the plant so I have suggested choose the capacity of your plant as large as the largest plant anywhere in the world when you do a literac search you will find that except when you have strong arguments against it it may be carbon footprint it may be the chemical nobody makes nobody uses whatever it is if you have a strong argument come up with a new set of capacity that is okay but from economics point of view uh you should use the largest plant um so and then of course plants Roots Etc locate the available capacity for your chemical all over the world identify the year of okay here you are going to tabulate you're going to do a literature survey say this chemical uh this is the capacity year of commissioning of each plant what technology is used tabulate all of these okay this is especially use useful for your first week report process flow diagram is extremely important um so I'm going to spend some time explaining what is expected of you this is the most important part of the report every group has to submit uh that has all the information about your project okay creating good PFD is extremely important this presentation gives a set of rules in the creation of PFD and writing the report okay uh use a minimum of 10 point font size so that it is readable when you give the report some of you you know the P PFD will go on becoming bigger and bigger so how do you accommodate you put small font font 9 font 8 font six can't read okay so then how do we accommodate a large PFD that I will tell you split the PFD into Parts okay with 10 point minimum font size constraint the PFD stream data may become large if large split the PFD into more than one page so as to include all streams if possible split the PFD into logical sections reaction section separation section Etc I'm going to give an example so here is um a sample report a submit subed by uh one of your seniors in the year 2020 21 this report by the way will be uploaded as a sample report on mle and um they got the best project uh award in that year so for example so this is PFD 2 part two so this this is the this is a diagram PFD this is the stream data similarly you have PFD part four that's what I mean don't make the font size small by trying to put the whole thing split it right split into if possible split the PFD into logical sections reaction section separation section and so on if that becomes big split that also and do not split the pfds unnecessarily okay just because somebody else has five pfds doesn't mean that there are some people who have done that in two pfds okay without creating too many problems try to use the space efficiently don't leave a lot of white space okay try to put them uh compact them drawing mode use the portrait or landscape mode as appropriate you might use a combination of these what is important is readability of the stream information and listing of all important streams okay provid space for stream information okay for example you might say that this is the space available for drawing PFD this is the space you saw in De Smith's report what they have done okay providing stream information variables on rows streams on columns okay please follow this these are variable uh stream uh numbers 17 18 19 20 because those are the numbers given here 17 18 and so on and then you have the variables face pressure temperature composition of flow rate of each of them these are all flow rates by the way and look at the units look at the units you have to give tons per hour don't give kg per second okay tons unless you have a specialty chemical small number give it in tons so that you have reasonable numbers here and then you should also give total mass flow rate total mass flow rate so that I can do mass balance by just by observation just by observation I can do a mass balance total flow rate and this should be in mass units not in molar units don't do this in molar units do it in mass units you might use molar thing for uh stochiometry and things like that but that's okay but here it should be on mass balance Mass rates mass units so that just by observation I'll be able to do the mass balance I should be able to say this stream is coming in this stream is going these streams are going out take a calculator just quickly add these and check what you are doing okay in fact you may want to do that by yourself somebody is doing the mass balance one of you have six uh people in the team somebody can quickly do the mass balance okay you can do the overall mass balance you can also do the component mass balance where there is only separation you can quickly do that okay so please you will come up with various things please don't do that this is something that we have found to be very useful just follow this so this is what I have I've given an example but then I Illustrated with de smi's report um stream units mention the units of all applicable uh variables units tons per hour uh degre Celsius okay give the temperature in degrees celsius don't give it in Fahrenheit don't give it in ranking don't give it in kelvin okay give it in engine give it in degrees celsius okay okay this is something I have already mentioned give the time units as hours not minutes not seconds uh giving the time units as hours will help you calculate the capacity of the plant for a year that is capacity of the plant right how do you do that how many working hours in a year roughly anybody told you this yeah somebody said that so you can take 3:30 working days about 24 hours so if you multiply that it comes to about 8,000 right so 8,000 hours so one can quickly if you give it in hours one can find the capacity of the plant just by multiplying by 8,000 so give it in hours not minutes not seconds okay temperature should be in degrees celsius not kin not degree F not ranking and so on what streams to include critical streams that help understand the operating conditions of a plant for example Outlet stream of a distillation column immediately as they leave so that I can understand what is a pressure what is a temperature and so on please put that it is possible that at the time of um when you get get it from the patent some information may not be there you might leave it out but you must figure that out and make it available at least subsequently because I need to know we need to know at what temperature this stream is coming out right Outlet streams of reactors outward streams of special units and then streams that help do a quick mass balance of every unit by observation if there are many streams obvious ones or that can be explained in the report can be left out for example supposing the only the pressure changes so you can leave it out okay the pressure increases or temperature only increases it's only a heater nothing else changes so some of these can be left out why you want to do that you may want to do that otherwise there might be too many streams you may want to leave out some of them but don't leave out the important ones that's a message okay in general all streams that matter give numbers to pfds as pfd1 PFD 2 Etc give stream give stream numbers such that we can find out which PFD they belong to I'll show you that here for example look at this DM says from PFD 1 number 17 right this is PFD part two if you go to PFD one look at the 17 here look at the 17 here and it goes to PFD 2 so you say where this is going and where it is coming from okay here it says from PFD to stream 26 if you do that right if you do that without this information PFD stand isolated not get connected they will be hanging loose you to tie them okay and then of course you can give some naming convention you can pfd1 can be numbered as hundreds 100 110 101 whatever uh 200 210 whatever you can do it like this uh it is okay whatever convention you use but please use a consistent notation for the equipment for the streams and so on and so forth okay description of the pfds in the report describe the flow with a special emphasis on the unobvious parts of the pfds for example reasons for a particular choice of equipment or operating conditions for example you might say I use Le chart as principle or series of compressors required to achieve high compression rate ratio I cannot achieve that ratio in one compressor so I'm putting two of them three of them whatever right I'm using low temperature because I want to prevent decompos so that cannot be included in the PFD per se but in the accompanying report you can actually write about that that is how your report should be your report should explain the obvious I mean unobvious not the one that you can easily see in the PFD and leave out the important ones don't do that and then low concentration required to prevent the poisoning of the Catalyst Etc is applicable okay if you do that then your description will be very good and then it'll be very easy for us to read the report and understand what you're doing I would want you to maintain two sets of pfds the approximate PFD with linear mass balance that you had presented that that is there of course we can always go back and check what you have done you would have submitted that report that is there the other PFD is a so you may just want to add a new PFD and this is a new PFD you can take it modify it but keep a copy of it this is what I proposed previously that's linear mass balance and then these are the this is the new one that is evolving one right the second one okay pfds with stream data with values this is the linear mass balance and this is with the simulator okay this is something I have already mentioned compare the results of the above two Mass balances and enter all results in a table if the difference is more than 1 person for any unit explain the reason okay the second set of PFD with stream data from converged simulation has to be used in the rest of the course okay because the first PFD is approximate gut feeling based on linear mass balance and so on that's fine later on you arrived at more concrete more rigorous please use the subsequent one for all future uh uh work so whenever the mass balance can be checked by the observation in the PFD no need to report repeat in the report it's already there I can easily check that right some people have the habit of copy pasting the PFD and putting it here that part of the PFD putting it please don't do all that not required okay I mean it's fine it makes your report maybe look colorful and maybe increases the number of pages but not required right do mass balance only when not obvious from PFD for example calculate and verify reaction stomry if any this is something you must do because in your uh in your table you're giving it in mass flow mass units so here if you want to validate something you might have you might have to you will have to show it in reaction reactors for example and there are many input and output streams you may want to show that do carry out energy balances in the report this may be done after the simulation after the simulation please do energy balance also uh this is what I have said do not copy paste we can read from the PFD itself that's why I keep saying PFD is extremely important try to produce a good PFD and we can go look at it put all your effort to come up with a nice one all the information should be there right yeah it's important to create a good set of pfds and refer to them repeatedly so simulating the flow sheet you might want to say what simulator you used whether it is partially converged fully converged extent of convergence any comment regarding how the flow sheet was converged um for some of you this may not make sense but uh you know do keep this it'll be useful to say what is it you have done details of reactors if possible what are the different reactors what reactor did he use did you use a conversion reactor did use rigorous kinetics so on and so forth equilibrium reactor there are different kinds of reactors you might use distillation shortcut column rigorous column KF column there are different columns that are there in whether it is dwc or S Plus you may just want to mention these are the units uh the equipment number and this is the model and then absorption extractive column and so on so you might say uh equipment list provide summary information of the equipment in a table like this how many pumps heat exchanger compressor whatever you don't have to give the cost uh details here in fact um um one of our previous examiners will say you know don't give the cost here information on pumps uh Delta P head type what fluid do not provide cost information in the above it does not make sense to know about the cost of pumps in a plant for example what is the total cost of all the pumps in a plant she says it didn't make sense it makes more sense to know about the total cost of all the equipment in the section of the plant say the reaction section information on heat exchangers process fluid the fluid that is getting um heat exchanger fluid whether it is water in out what Duty what material and so on column information please mention whether the numbering is from the top or from the bottom okay numbered from Top numbered from bottom right then it becomes very easy for the reader to understand what you're doing okay where is the feed stage okay and where you might have multiple feeds so it'll be better to say that okay validation of the plant cost one of the important things is you will come to the you will calculate the cost of the plant there will be an there is an indirect way there is a second way to validate it with the cost of a similar plant somebody else might have uh come up with a plant and in fact we found interestingly for many of the plants this exercise could be done okay somebody come up somebody inaugurated a new plant started it went into production okay by so and so capacity this so much cost I mean these are all rough numbers published in papers so take the information apply the scaling factor in estimating the cost if it is established at some other year apply the time factor in estimating the cost if it is in some other country apply the country conversion factor so it should be possible to do that and say this is what is the cost and I have arrived at this cost right by doing detailed calculation saying that my I'm using this distillation column you know I'm using this reactor I'm using this pump the cost is this detailing the cost of each unit totaling it this is the cost right and of course there are other rules um as you would see in the in the references that I pointed out operating cost and you know various other cost so on I think this is the we are very close to the end do not increase the pages do not increase the number of pages unnecessarily long report does not mean higher marks okay okay a sample report I already showed uh this is the d smi's report uh if you click this uh it'll take you if you are already logged into Moodle it'll be posted there um is a link to a report that follows these rules whatever I mentioned right so that is the last slide that I have so I try to summarize uh you know the conduct of the course there will be many other things as we go along it's very difficult to uh you know put all of those in the form of rules and regulations um although I said that finally your panel examiners uh decision is final okay because they might say I want to want you to do it in this particular way so that that's perfectly fine okay supposing I had said that use landscape mode for PFD and your panel says no portrait absolutely fine please do portrait so I'm going to go by whatever uh your panel uh your examiners tell you and um um it I I believe that it's a very very exciting course okay very exciting course but uh you know it it might even be um like Dungeons and Dragons right very I don't know how many of you have played Dungeons and Dragons anybody played okay not so bad you don't get killed here right Dungeons and Dragons I used to get killed so many times right but uh and by the way I wanton it once right only once in of course I don't play now I'm too old to play but I used to play when I was young and um lot of uh exciting things lot of opportunities right I think you will like the course if you like chemical engineering you like the course it is possible in fact I would believe that some of you would start liking the liking chemical engineering after doing this course okay it is possible that some of you didn't like chemical engineering so much but after this course it's a very really really exciting course okay so I'm going to stop here thank you
