摘要: 用ASPEN PLUS 11.1软件对Fischer-Tropsch合成水相副产物中提取丙酮和甲醇工艺进行了模拟计算。在不同的条件下，对以水作为萃取溶剂的萃取精馏塔和溶剂回收塔进行了模拟和优化，得出了整个流程的最佳工艺。萃取精馏塔：溶剂和原料的体积比为1.00，采出率为4.56%，回流比为2.00，塔板数为36，在第8块塔板和第18块塔板分别进料溶剂水和原料；原料和溶剂的最佳温度325.15K和328.25K。溶剂回收塔：采出率为42.10%，回流比1.00，塔板数为19，在第13块塔板进料。在该工艺条件下进行了实验研究，实验结果和模拟计算相吻合，从而验证了模拟结果的可靠性。

Abstract: The simulation of producing acetone and methanol from water phase product of Fischer-Tropsch synthesis was carried out by the software of ASPEN PLUS(model version 11.1). Under different conditions, the simulation and optimization of the distillation columns were made and the optimal operation parameters of the whole process were obtained. Extractive distillation column: the volume ratio of solvent to feed is 1.00, the mass ratio of distillation to feed is 4.56%, the reflux ratio of mass is 2.00, the numbers of theory stage of extractive distillation column is 36, the numbers of solvent stage of extractive distillation column is 8 and the numbers of feed stage of extractive distillation column is 18, the optimal temperature of feed is 325.15K and one is 328.25K for the solvent water. Solvent recovery column: the mass ratio of distillation to feed is 42.10%, the reflux ratio of mass is 1.00, the numbers of theory stage of solvent recovery column is 19, and the numbers of feed stage of solvent recovery column is 13. Through the comparison of data between simulation and experiments, the reliability of simulation was testified.-
