| 摘 要： | 以49万t规模甲醇制丙烯(MTP)流程为研究对象，考察了高温醚化+前脱丁烷、高温醚化+前脱丙烷、低温醚化+前脱丁烷、低温醚化+前脱丙烷4种技术组合的经济性能。在4种技术组合中，低温醚化+前脱丙烷的技术组合能耗(502 MW)、公用工程费用(加热冷却公用工程费用622×108 RMB yuan/a)，CO2排放量（2023×109 kg/a），〖JP〗能效(07107)等指标更优，更具有竞争力。产品分离过程的能耗占全流程能耗的50%以上，因此分离单元的优化改进是提高甲醇制丙烯流程能效的关键。

| Abstract: | Based on the 049 million tons scale methanol to propylene (MTP) process, the technology combinations of high temperature methanol to dimethyl ether (MTD) and front end debutanization separation process, high temperature MTD and front end depropanization separation process, low temperature MTD and front end debutanization separation process, low temperature MTD and front end depropanization separation process were studied. In the four combinations, the combination of low temperature MTD and front end depropanization separation has the lowest energy consumption (502 MW), the lowest energy cost (622×108 RMB yuan/a), the lowest CO2 emissions（2023×109 kg/a） and the highest energy efficiency (07107), thus, it is most competitive. The energy consumption ratio of product separation unit exceeded 50%, so that the energy conservation and improvement of this part will be the key point for enhancement of MTP process. |
