The statement could be right if you've clear the concepts of subcooling, bubble point and dew point (see below). Please judge the following statement: I will have a total condenser which will only remove latent heat and therefore vapour at its boiling point will go in, liquid at its boiling point will come out. The third advice is to qualify yourself and your scope in such a way that we can understand the best paths to help you.Р”Р„nd now, following your request, I'll try to give some answers: The second advice is to go to your teacher and to ask him the same questions you've written in your post.

I totally agree with Bobby and Art answers and my first advice to you is to take in high and serious consideration what these two 'very-senior-experts' are trying to communicate to you. If it is an assignment, then identify is as such and submit your detailed work to date on this task for the Forum to see where you are making errors or not applying the correct procedure(s). You don't project the basic knowledge of how a column is designed, so it is hard to imagine how you have either been assigned this task or are doing it as general interest. What you seem to seek is the answer to the problem and not the methodology and procedure to resolve the design of a distillation problem - which is what your instructors are charged with teaching you. We on the Forum cannot teach you Unit Operations that is the function of your university. We all have to speak a common language at the same level of knowledge. This will result in hindrance and confusion rather than help. Without knowing the basics, the Forum member are going to be communicating over your head while trying to help you. This comment is not mean to offend you, but rather to help you understand that you seem to lack a lot of basic understandings on a distillation Unit Operation.

Based on your assertions and algorithm, you are displaying little knowledge on how a distillation column operates and how to design it - OR your instructors have failed in teaching you the same. Unfortunately, what Bobby is stating is the honest truth. Then I could also say that Lm is liquid at its boiling point and vm is vapour at its boiling point? By making the assumption of well lagged I should be able toР’В say that there is negligible heat loss across the column.Р”В¬ould I then just do the same thing for the condenser? Ive done the mass balance, so I can calculate the boiling point of the stream? Then assume that it only removes latent heat, so that the temperature of vn = the temperature of Ln and D? So now I know my feed stream temperature. This should be adjusted using perhaps a depriester chart, but as this is initial designs, this should suffice. Individual Boiling points respectively are 125 РІВРЉ ,151 РІВРЉ and 174.1 РІВРЉ. I am aware that I am not a master at this, hence my question.Р”Р„ttached is a very crudely (haha) drawn diagram of a labeled distillation column. Unfortunately that doesn't help in the slightest. I'm really sorry about the explanation, i'm not sure if this will make sense. How should I go about deciding on temperatures of the distillate and bottom?Р”Р„ny help in the right direction would be greatly appreciated.

Therefore if I use a total condenser, then I just remove the sensible heat and latent heat using the condenser until the stream is now at its new temperature which makes it liquid at its boiling point? Say, X2.? Would I be right in assuming that the temperature of the column is the same throughout? And therefore before the condenser the temperature is also X.

I need these temperatures to complete an energy balance.Р”Р‡or the feed I was going to keep it as liquid at its boiling point and therefore just find the temperature of the stream by using the individual components boiling points. My question is for initial design, how do I select temperatures for the Feed, Before/after condenser and before/after reboiler. The reason for 5 is so that the strict properties of petrol can be upheld.

I am designing a total of 5 distillation columns to separate pyrolysis oil into petrol/diesel/benzene/heavy-hydrocarbons.
