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 (ing) = i mol/h Bottoms from second still (4) = mol/h Benzene mole fraction in bottoms from second still (X4B) = Toluene mole fraction in bottoms from second still (47) = i

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 (x4T) = i

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.
