The pulse-control operation technique which alternates between total reflux operation and total efflux operation in batch distillation was studied along with the minimum amount of slop cut. Total reflux time was confirmed by dynamic simulation, and total efflux time was adopted by statistic method. For the mixture of hexane and cyclohexane and the traditional constant reflux ratio operation strategy, the amount of slop cut is 1.8-2.1 times of the minimum amount of slop cut; whereas for the pulse-control operation strategy, it is 1.2-1.4 times of the minimum amount of slop cut. So compared with the traditional constant reflux ratio operation, the pulse-control operation can decrease the amount of slop cut and operation time, and meanwhile, enhance separation efficiency and yield.
