贫甲醇液泵在低温甲醇洗中的实践应用

Application of lean methanol liquid pump in Rectisol

介绍了某化工有限责任公司40万t/a乙二醇项目低温甲醇工艺流程,其中贫甲醇泵作为低温甲醇洗工艺系统的主洗泵,以其高利用率、可提供动力,技术成熟等特点被广泛应用于化工工艺设备中,其运行稳定是工艺系统正常运行的关键。

This paper introduced that the low-temperature methanol process flow of a 400 thousand ton/year ethylene glycol project of a chemical limited liability company,in which the lean methanol pump was used as the main wash pump of the low-temperature methanol wash process system,with its high utilization rate,power,mature technology and other characteristics.It is widely used for chemical process equipment,and it is the key to normal the process system operation with its stable operation.
