The feed (F) to a separation process enters at 200 mol/min and contains 40 mol% ethanol and the remainder water. The separator can only process 120 mol/min of input feed; therefore, it is proposed to introduce a bypass stream that contains 80 mol/min of the input feed (same composition) (B) that joins the waste stream after it exits. The product stream (P) is pure ethanol and leaves the overall process at a rate of 2 kg/min. What is the molar flow rate and molar composition of the final waste stream (W) that leaves the overall process? Species ethanol water F Chemical Formula CH5OH HO B Molecular Weight 46.07 18.02 P W a) Draw a complete flowchart for this process and state any assumptions. Label all unknown variables appropriately. b) Write and simplify the general balance equation for this process. c) Solve for the molar flow rate and molar composition of the final waste stream (W).
