Investigation of ethyl acetate reactive distillation process

摘要

In this paper, an extensive of ethyl acetate synthesis by homogeneously catalyzed reactive distillation is presented . Reactive distillation is a promising operation whereby reaction and separation take place within a single distillation column. The synegistic effect of this conbination has the potential to increase conversion, improve selectivity and facilitate separation tasks. The feasibility of ethyl acetate synthesis is examined using the teactive distillation lines diagram. A completely rate-based simulator DESIGNER developed within the framework of a large European research projects is used in order to predict concentrations, temperatures and other important process variables . In order to validate theoretical predictions, a set of reactive distillation experiments is performed in galss tray column with 80 bubble cap traps. The concentrations and temperature profiles computed by EDSIGNER agree well with the experimental data
