Abstract

This work has been carried out to simulate and analyzethe economic advantagesof the conventional and the reactive distillation process methods used for the production of ethyl acetate throughthe Fischer esterification reaction between acetic acid and ethanol withthe aid of Aspen Plus.The conventional and the reactive distillation models of the process were developed in Aspen Plus environment by employing an equilibrium reactor and a packed RadFrac column having 23 segments including the condenser and the reboiler. For the reactive distillation process method, the main column was divided into three sections, namely the rectifying(upper), the reaction (middle) and the stripping (lower) sections, but in the conventional process method, the main column was only divided into the rectifyingand the stripping sections. The esterification reaction, occurring in the reactor of the conventional method and in the reaction section of the reactive distillation method,of the process was modeled as an equilibrium type. The higher purity of ethyl acetate, the lower total capital cost, the lower operating cost, the lower total utilities cost, the lower equipment cost and the lower total installed cost obtained from the reactive distillation process method have revealed that, inthe production of ethyl acetate using the Fischer esterification,the reactive distillation process method was found to be better than the conventional process method both in giving ethyl acetate in higherpurity and economically
