Abstract
Base on the process simulation of hydrogenation of acetic acid to ethanol and the modified NRTL model, the effects of the operating parameters, including the stage number of distillation column, the number of feed stage and reflux ratio, on the separation process were investigated by using Aspen Plus software. The result shows that when ethanol annual outputis0.2 million tons, the optimum operating parameters are as follows: the stage number of distillation column T1 is 43, the feed stage is No.30, reflux ratio (molar ratio) is 0.64; the stage number of distillation column T2 is 40, the feed stage is No.14, the reflux ratio is 11.8;and the stage number of distillation column T3 is 45, the feed stage is No.42, the reflux ratio is 2.9. Under the optimized separation parameters, the reboiler duty can reduced by 39%. The simulation results of temperature and gas-liquid concentration distribution on each column plate can be achieved. It has great significance for further industrialization.关键词
