Dew point problem 2) A vapour mixture containing 40% cyclohexane, 20% benzene, 25% toluene, 15% n- heptane is in equilibrium with its liquid at 1 bar. Determine the dew point temperature and liquid composition. Consider the vapour phase as ideal and the liquid phase non-ideality is adequately represented by UNIQUAC model. The volume parameters, interaction parameters are given below.
