分子筛脱水单元的高效运行对天然气处理至关重要,分子筛过快失效将严重制约气体处理装置的安全、平稳、高效运行。本篇探讨了大涝坝集气处理站分子筛脱水单元存在的问题,对问题原因进行了分析,并且开展了一系列实践验证工作,发现了原料气含蜡对分子筛失效的重大影响,并有针对性地提出了提高分子筛脱水单元高效运行的措施。 The efficient operation of molecular sieve dehydration unit is essential for natural gas treatment. The rapid failure of molecular sieve will seriously restrict the safe, smooth and efficient operation of the gas treatment unit. This article discusses the Dalaoxba gas processing unit molecular sieve dehydration unit of the existing problems, the causes of the problem were analyzed, and carried out a series of practical verification work found that the feed gas wax on the failure of molecular sieve significant impact, and targeted Proposed to improve the molecular sieve dehydration unit efficient operation measures.
