双吸收低温甲醇洗工艺应用总结

Sum-Up of Use of Double Absorption Low-Temperature Methanol Wash Process

介绍了双吸收低温甲醇洗工艺流程,并对其工艺要点进行分析。结合生产过程中洗涤后的净化气中CO2含量超标、甲醇损失量大、系统甲醇液位波动及系统腐蚀等问题进行分析,提出了相应的解决措施。

The process flowsheet is presented of double absorption low-temperature methanol wash, and an analysis is given of its process essentials. An analysis is carried out of its problems in process, viz., the CO2 content of the purified gas after scrubbing exceeds the standard, loss of methanol is high, liquid level of methanol in the system flutters, and the system is corroded, so relevant measures for their solution are put forward.
