摘要：
In order to solve the problem of low ethanol conversion in the production of ethyl acetate via esterification of acetic acid and ethanol, a pervaporation-esterification coupling technology was proposed. A mathematic model of the pervaporation membrane reactor (PVMR) was established using the Aspen Custom Modeler and verified with the experiment results. Effects of reaction temperature, acid to alcohol ratio and membrane area to reaction liquid volume ratio on process performance were investigated in detail by Aspen Plus. The results show that there is a positive correlation between ethanol conversion increment and reaction temperature. With the increase of acid to alcohol ratio, ethanol conversion increment increases first and then decreased. The performance of PVMR is improved by enhancing the ratio of the membrane area to the volume of the reaction liquid. The optimum conditions were investigated as follows: reaction temperature 90 °C, acid to alcohol ratio 2, and the ratio of the membrane area to the volume of the reaction liquid is 100 m-1. Under the optimal conditions, ethanol conversion was 82.4% in the PVMR process. The results are useful in energy saving integrated PVMR processes for ethyl acetate production. © 2023 Zhejiang University. All rights reserved.
