Pure ethyl alcohol is produced by feeding a distillation column 40% alcohol solution (the remainder water) mixed with benzene. The benzene serves as a promoter of the process. The distillate from the top of the column consists of 75% benzene, 24%water, and 1% pure ethyl alcohol. The product is pure ethyl alcohol recovered at the bottom. The process must produce 550 kg/hr of pure alcohol. Find the required feeds of 40% solution and benzene and the amount of pure alcohol lost at the top of the column.
Please lemme know an answer as soon as possible, been stuck on this problem for a while.
