| Abstract: | A novel process flow was proposed by using calalyzed rectifying partition wall for the synthesis of ethyl acetate,in which the catalyzed rectifying partiction wall column was used instead of conventional calalyzed rectifying column and ethyl acetate column.Both the new process flow and conventional process flow were simulated with Aspen Plus.Liquid phase composition profile and temperature profile of the two processes were compared.The effect of liquid phase distribution ratio on the performance of the nove... |
