Question 3: Consideration is being given to a system whereby the vapour from the top plate of a distillation column enters a partial condenser, which is operating at a total pressure of 0.8bar. The vapour is condensed to a 35/65 molar ratio mixture of liquid/vapour. The composition of the vapour from the condenser is to be as follows: Benzene = 70mol% Toluene = 25mol% Xylene = 5mol% The condensed liquid is then passed to the top tray as reflux. a) Calculate the approximate temperature in the condenser together with the compositions of the vapour leaving the top tray and the liquid product from the condenser. b) If due to operations in the water cooling system it is possible for the condenser temperature to rise by 3K, estimate, numerically, the effect on the degree of condensation. c) How will this affect the column operation?
