摘要
利用Aspen Plus模拟软件对C_(4)氧化生产MMA原料预分馏工段工艺流程进行模拟,并利用Aspen Plus中Sensitivity模块对T1001塔进行优化。根据物系性质选择NRTL热力学方程,采用RadFrac模块建立模拟流程并进行计算;考察了操作参数对T1001塔塔顶产品中异丁烯及正丁烷回收率的影响,得到优化的操作参数:理论塔板数97、回流比3.2、塔顶压力5.43 bar、萃取剂进料位置第11块板、萃取剂进料温度45℃,此时塔顶产品中异丁烯的回收率达99.6%,正丁烷的回收率为0.8%。
The raw material pretreatment section of MMA technological process from C_(4) was simulated by using Aspen Plus.The tower T1001 was optimized by using sensitivity module in Aspen Plus.The simulation process was established and calculated by selecting NRTL thermodynamic equation and RadFrac model according to the system properties.The effect of operating parameters on the recovery rate of isobutylene and n-butane in the top product of T1001 tower was investigated.The optimized operating parameters were obtained:97 of theoretical plate number,3.2 of reflux ratio,5.43 bar of tower top pressure,11th plate and 45℃of extractant feeding position.Under the optimized conditions,the recovery rate of isobutylene and n-butane in the top product was 99.6%and 0.8%,respectively.
