Question: c) A feed stream consisting of ethanol (E), butanol (B), and propanol (P) is fed to the distillation column for separation. Component E's mass flow

c) A feed stream consisting of ethanol (E), butanol (B), and propanol (P) is fed to the distillation column for separation. Component E's mass flow rate is 100kmol/s, and the flow rates of components B and P are unknown. The distillate flow rate is 100kmol/s and contains 60kmol/s of component E and 40kmol/s of component B. It has been found that 40% of component E in the feed stream ends up in the bottom stream. The distillate and bottoms flow rates are equal. Draw and label the process flowchart, and perform DFA. [4 marks]
