1. The feed to a distillation column is a binary mix of liquid and vapor q=1/2, and at 100kmol/h and xF=0.5 A side stream of saturated liquid is withdrawn at 15kmol/h with xS=0.7. If xD =0.95 and xB=0.125, calculate D and B. If L/V=0.7, calculate L'/V' and L/v. Sketch what the operating line will look like under an assumed equilibrium curve. There is no need to calculate the number of stages
