Problem 1 Integrate physical properties with a Mass and Energy balance on a distillation column Consider the distillation separation problem in Assignment 4, problem 4. For the exact conditions that you solved in the mass balance, we will solve the energy balance. The Flow diagram, stream table and T-x-y diagram are shown below. (To refresh your memory, you can find both the question, and the solution on e-class.
