摘　　要：某化工装置反应单元需要用到大量甲醇作为溶剂,甲醇回收采用常规精馏工艺能耗过高。研究旨在借助AspenPlus软件进行流程模拟计算,对脱甲醇塔采用热泵精馏技术进行节能优化及经济性评价。结果表明:热泵精馏方案节能效果明显,改进后预计投资回收周期约1.4年,经济效益及应用前景较好。The reaction unit of a chemical plant needs to use a large amount of methanol as a solvent,and the energy consumption of methanol recovery by conventional distillation process is too high.Aspen Plus software was used to simulate the process,and heat pump distillation technology was used to optimize the energy saving and economic evaluation of the demethanol tower.The results show that the energy saving effect of heat pump distillation process is obvious,and the expected investment recovery period after improvement is about 1.4 years,which has a good economic benefit and application prospect.
