System ooundary-J/ ndenser Distillate 85% EtOH 15% H20 Feed 35% EtOH 65% H2O Distillation Column Waste 5% EtOH 95% H20
Expert Answer
Let the basis of the process be taken as 100 kg feed (F). Apply material balance on the overall process across the given system boundary. The total mass balance is given by equation (1) and the mass balance on ethanol (EtOH) is given by equation (2).
Solve equation (1) and (2) simultaneously to get the value of D and W as:
Now, calculate kilograms of distillate (...
