摘要:
为了提高异戊二烯萃取精馏装置的工艺设计精度,在运用化工流程模拟软件Aspen Plus,对二甲基甲酰胺法分离异戊二烯的工艺流程进行模拟计算时,引入反应精馏和反应萃取精馏技术,考察各塔内双烯烃微量反应对分离过程的影响。模拟结果与实验数据和传统模拟方法得到的结果进行了比较。结果表明:含反应的流程模拟计算结果更符合实际生产情况; 精馏塔内微量反应对脱重塔的出料组成影响较大,使产品中异戊二烯的质量分数和质量收率分别降低了0.4%、0.5%,无法达到原定设计要求。通过调整脱重塔塔顶出料量,可以使含反应精馏过程的异戊二烯的质量分数和质量收率重新达到设计要求。
Abstract:
In order to improve the design accuracy of dimethyl formamide separation process for polymer-grade isoprene, the reactive distillation and the reactive extractive distillation were introduced when the process was calculated by Aspen Plus software. Besides, effects of diolefins reactions on simulation results of the separation process were investigated. Simulation results and experimental data were compared with results of traditional simulation method. It was found that simulation results of the modified method were more suitable for the practical manufacturing situation. Moreover, the microreactions had a significant impact on product compositions of heavy fraction separation column, and then the quality fraction and yield of polymer-grade isoprene were reduced by 0.4% and 0.5%, respectively. To meet design requirements of the isoprene mass fraction and the yield in product, the overhead outflow of the heavy fraction separation column was ajusted.
