摘要
Abstract
The dehydration process of crude ethanol vapor with 84.2%(x) C2H5OH through pressure swing adsorption was studied by means of the Aspen Adsorption software. The axial distribution of H2O adsorption quantity at different time was obtained,and the adsorption cycle was determined by solving the utilization level of the adsorption column. The influences of adsorption pressure and adsorbent volume on the adsorption process were investigated. It was showed that,the adsorption cycle of the ethanol dehydration with the pressure swing adsorption was related to the adsorption capacity of the adsorbent column at different time,which was 15 800 s;when the utilization rate of the adsorption column was 1,the adsorption column was saturated and the gas composition at the outlet was the same as the composition of the raw gas;Increasing operating pressure could enhance the adsorption capacity of the adsorption column,but the energy consumption also increased;when the absorbent volume increased, the simulating mass transfer coefficient should be decreased.关键词
