Question
A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation column. The bottoms product contains 98.0 mole% X and no B, and 81.0% of the X in the feed is recovered in this stream. The overhead product is fed to a second column. The overhead product from the second column contains 95.5% of the B in the feed to this column. The composition of this stream is 94.0 mole% B and the balance T. Show all the details in flow diagram and label all the stream. Show your solution and write readable. Thank you.
A.) Write three balances and use one constraint for the performance of Still 1 to solve for the following quantities for a process feed ( n) of 300.0 mol/h. Bottoms flow rate (n₂) = i mol/h Overhead fow rate (n3) = i mol/h Benzene mole fraction in overhead (X3B): i Toluene mole fraction in overhead (x37) = i B.) Write three balances and use one constraint for the performance of Still 2 to solve for the following quantities for a process feed (₁) of 300.0 mol/h. Overhead from second still (n) = i mol/h Bottoms from second still (4) = mol/h Benzene mole fraction in bottoms from second still (X4B) = i Toluene mole fraction in bottoms from second still (47) = i
