摘　　要：采用Aspen Plus软件对C_(3)选择性加氢能量耦合催化精馏工艺进行模拟与控制,将碳三选择性加氢反应置于丙烯精馏塔内,在分离的同时实现MAPD的加氢脱除,再用丙烯精馏塔的塔顶采出作为脱乙烷塔塔釜再沸器的热源,这样有效地降低了反应过程的能耗,降低了投资成本。结果表明:经过模拟,确定能量耦合催化精馏工艺的总理论板数为15块,进料位置为第7块塔板,回流比为1.15;采用能量耦合催化精馏工艺,使催化加氢选择性提高47%~54%,丙烯产率提高43.94%。Aspen Plus software was used to simulate and control the energy coupled catalytic distillation process of C_(3)selective hydrogenation. The C_(3)selective hydrogenation reaction was placed in the propylene rectification tower, and the hydrogenation and removal of MAPD was realized during the separation. The top of the propylene rectification tower was used as the heat source of the reboiler of the deethanizer tower, which effectively reduced the energy consumption of the reaction process and the investment cost. The results showed that, after the simulation, the total number of theoretical plates for the energy-coupled catalytic distillation process was 15, and the feed position was the seventh plate, and the reflux ratio was 1.15;Using the energy-coupled catalytic distillation process, the selectivity of catalytic hydrogenation was increased by 47%~54%, and the yield of propylene was increased by 43.94%.
