Numerical solution of adsorption cycle in ethanol dehydration process

摘要

A water removal process was investigated by pressure swing adsorption-desorption cycle. Simulation calculations were carried out for the conditions of the dehydration process. The adsorption stage was simulated using a mathematical model based on material and momentum balances for water and for the ethanol-water mixture. The mathematical model of the process was solved by the method of finite differences centered. It is shown that mathematical model adequately describes the process.
