摘　　要：提出了带有冷存料塔釜的热敏物料间歇精馏流程,该流程包括冷存料塔釜、预热 冷却器、循环泵、蒸发器和精馏塔及冷凝器。该过程的设备降解指数比常规间歇精馏过程小得多。通过模拟计算,研究了回流比、预热 冷却器面积、塔釜冷却量、蒸发器加热量以及泵循环流量对热敏精馏过程的影响。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.
