【Abstract】 A new type of batch distillation process with dynamic accumulation and varying pressure is proposed,and has been used in the industry successfully.The results show that,compared with the conventional type of batch distillation process,the new process shortens the period of operation greatly,improves the separate efficiency apparently and cuts down the operational expenditure.更多还原
