【Abstract】 In order to optimize heat pump distillation process,the five-hiberarchy strategy of construction heat pump distillation is pro- posed,based on the characteristic and applied area about compressed heat pump distillation.By solving each hiberarchy respectively, the complex is solved in constructing heat pump distillation process.Based on characteristics of crude benzene ethylene tower and pro- posed strategy of heat pump distillation,the tower has been carried on flow-simulation on heat pump distillation flows by using the process simulation software-ECSS.The results verify the establishment of the proposed strategy and algorithm of optimizing design to produce the superior flowsheet of heat pump distillation.更多还原
