Determine the cooling duty, Q for the condenser.

A vapor stream of wt fractions 45% H2O, 40% benzene, 15% acetone flows at 90°C and 1 bar into a condenser at 100 kg/h. The stream is condensed and forms two liquid phases. The water and benzene can be considered to be totally immiscible in one another. The acetone partitions between the benzene and water layer, such that the K-ratio, K = (wt. fraction in the benzene layer)/(wt. fraction in the water layer) = 0.9.a The liquid streams exit at 20°C and 1 bar. Determine the cooling duty, Q for the condenser. Assume the feed is an ideal gas and the liquid streams are ideal solutions once the immiscible component has been eliminated.
