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。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 effective running of molecular sieve dehydrating unit is very important for natural gas processing. If molecular sieve dehydrating unit becomes invalid too quickly, it will restrict the safe, stale and effective operation of gas processing plant. The reasons for problems in molecular sieve dehydrating unit in the Dalaoba Gas Collection Station are discussed, and a series of practices are carried out. It has been found out that wax brought out by natural gas is harmful for molecular sieve’s efficiency. Some measures to improve the efficiency of molecular sieve dehydrating unit are proposed.
