Process simulation and optimization of reaction unit in bisphenol A plant based on Aspen Plus software
A simulation model for the reaction unit of synthesis of bisphenol A plant by ion exchange resin was built by Aspen Plus process simulation software.The feed temperature,the mass ratio of phenol/acetone and the ratio of acetone to the first stage reactor were investigated.The effects of main operation conditions on conversion rate of acetone,yield of bisphenol A and selectivity were analyzed and optimized.The results showed that the yield of bisphenol A and the conversion rate of acetone in-creased with the increase of feed temperature,the decrease of mass ratio of phenol/acetone,or the in-crease of the proportion of acetone to the first stage reactor under the case of single factor variation.Un-der the optimized conditions of the first and second stage reactors feed temperature of 65,76℃,mass ratio of phenol/acetone of 15.0,and mass ratio of acetone to the first stage reactor of 1.00,the yield of bisphenol A and conversion rate of acetone could be increased by 3.96 and 4.30 percentage points,re-spectively.
