Rezumat:

A theoretical study of reactive distillation processes to remove acetic acid from its 30 wt% aqueous solution by esterification with n-butanol is presented. Two different column structures were identified, rendering theoretically close to 100% conversion of acetic acid. A model capable of precisely predicting the potential phase splitting is used. Total costs for the new processes are estimated and compared with estimated costs of nonreactive separation process. It is shown that more than 56% costs can be reduced by using the new processes. The dynamic behavior of both the processes is studied through a series of dynamic simulation runs.
