Simulation of tert-butanol dehydration to produce isobutylene by catalytic distillation
摘要
Abstract
With mass fraction 85% tert-butanol (TBA) as feed, the process of TBA dehydration to produce isobutylene by catalytic distillation was simulated. The sulfonic acid cation exchange resin was self-prepared, and kinetics subroutine interface was powered by Fortran. Aspen Plus was used to investigate the TBA conversion of key factors such as number of reaction stage, operation pressure, reflux ratio , number of rectification stage and stripping stage,and feed stage location. In the condition of TBA flow rate 100 kg/h,each reaction stage loaded with 45 kg catalyst and isobutylene produced from the overhead,the simulation results show that TBA conversion is 99. 5% , under the condition of 4 stages in rectification section, 5 stages in reaction section, 4 stages in stripping section, operation pressure 0. 35 Mpa,reflux ratio 1. 5 ,and feed stage 4.关键词
