【Abstract】 The operational mode of dynamic accumulative batch distillation was Proposed. The theoretical and experimental results show that the new mode of operation in which the concentration shift in side the column eliminates the fly wheel effect of the process can improve the separation significantly. The experiments recited in the paper shorten the operation time more than 20% and 40% respectively with the comparison to conventionalbatch distillation.更多还原
