摘要
介绍了茂名乙烯2号裂解装置自2006年9月投产以来三元制冷系统存在的问题,及在2010年利用大修停车检修时进行的技术改造。对三元制冷压缩机一段吸入罐带液问题,三元制冷系统与乙烯精馏塔系统不匹配和乙烯精馏塔塔压高问题及三元制冷系统与冷却水温度不匹配问题进行了剖析,并提出相应的优化措施。
This article introduces the problems in tertiary refrigeration system for the expanded ethylene plant in Maoming since it was put into production in September 2006 and its technical modification during the overhaul in 2010,analyzes the problems including the accumulation of liquid-level in the first suction drum of tertiary refrigeration compressor,the mismatch between tertiary refrigeration system and ethylene tower,the high pressure in ethylene tower,and the mismatch between tertiary refrigeration system and cooling water temperature,and finally provides corresponding solutions for optimization.
