【摘要】 为解决甲醇合成塔泄漏带来的相关问题，重庆万利来化工股份有限公司采用绕管型甲醇合成塔实施了效能提升项目。介绍了绕管型甲醇合成塔替换管壳式甲醇合成塔的工程应用情况，包括改造内容、开车运行情况、改造前后能耗及经济性对比，改造后生产运行数据表明：甲醇产量增加10%左右，合成塔及回路压降明显下降，吨甲醇的天然气消耗、电耗都有所降低，可为相关的新建或改建甲醇合成装置提供参考。更多还原

【Abstract】 In order to solve the related problems caused by the leakage of the methanol synthesis tower, Chongqing Wanlilai Chemical Co., Ltd. had implemented an efficiency improvement project by adopting the coil-tube methanol synthesis tower. The engineering application situation of replacing the shell-and-tube methanol synthesis tower with the coil-tube methanol synthesis tower was introduced, including its renovation contents, operation performance, as well as the comparison of the energy consumption and economy before and after the renovation, which showed that the methanol output had increased by about 10%, the pressure drop of the synthesis tower and the loop had decreased significantly, and the natural gas consumption and electricity consumption per ton of methanol had both been reduced. It could provide a reference for the relevant newly-built or reconstructed methanol synthesis plants.更多还原
