A mixture of 16,500 kg/h of 55 wt% methyl acetate and 45 wt% methanol is to be separated into 99.5 wt% methyl acetate and 99 wt% methanol. Use of one homogeneous azeotropic distillation column and one ordinary distillation column has been suggested. Possible entrainers are n-hexane, cyclohexane, and toluene. Determine feasibility of the sequence. If feasible, prepare a design. If not, suggest an alternative and prove its feasibility.
