For binary flash distillation, we discussed in class that there are 8 variables (F, ZA, V, ya, L, XA, P and T) and 4 equations derived from VLE and mass balances. Thus, we typically require 4 of these variables to be given so that we can obtain a unique solution to the problem. Let's say, your manager tells you that he has a feed mixture with 2 components (given F, za) and he requires you to come up with a flash column that can produce a certain desired amount of Vapor product (thus V, ya are specified). Identity of both components is known and all VLE data has been provided to you. Has the manager given you enough data? If yes, give a step-by-step description of how would you go about designing the flash column (basically find P and T)? If no, why?
