摘要
某石化公司35 kt/a丁二烯装置使用N-甲基吡咯烷酮作为萃取溶剂,在NMP方法生产丁二烯的工艺中,NMP中水含量的控制,对装置的正常生产起到至关重要的影响,水含量过高易造成溶剂选择性能变差、溶剂系统热源不足、主洗塔压差波动等危害,文中对丁二烯装置NMP溶剂中水含量的控制经验进行了总结。
The 35 kt/a butadiene unit of a petrochemical company uses N-methylpyrrolidone as the extraction solvent.In the NMP method for butadiene production,the control of water content in NMP plays a crucial role in the normal production of the unit.Excessive water content can easily cause poor solvent selection performance,insufficient heat source in the solvent system,and fluctuations in pressure difference in the main washing tower.This article summarizes the experience in controlling the water content in NMP solvent of the butadiene unit.
