Q2: One kilomol of a mixture of A and B (Z₁=0.5) is passed through a heat exchanger and then flashed to vaporized 30% of the feed .The molar enthalpies of saturated liquid 5°C) may be expressed as: and vapour at 1 atm total pressure (reference temp. HL 9000+ 1000*(x) kJ/kmol; HV 35000 + 8000*(y) kJ/kmol. The relative volatility is aAB = 1.8. Calculate : a) The concentrations and enthalpies of liquid and vapour products, b) The heat supplied to the feed.
