Abstract A distillation process for the separation of heat sensitive material is proposed.The equipment for such a process is made up of a cold still pot,a preheat-cool exchanger,a pump,an evaporator,a distillation column and a condenser.The degradation index of such a process is much less than that of conventional batch distillation process.By simulation,the effects of reflux ratio,the area of the preheat-cool exchanger,cool duty of still pot,heat duty of evaporator and the liquid flow recycled by pump on heat sensitive material distillation are studied.
