2 **6.1.5 A distillation process is shown in Figure P6.1.5. You are asked to solve for all of the values of the stream flows and compositions. How many variables and unknowns are there in the system? How many independent material balance equations can you write? Explain each answer and show all details of how you reached your decision.
