高H2S高CO2高Cl-天然气压力容器设计

摘要

The basic designing practices of pressure vessels for natural gas field with high H2S ,CO2 and Cl- contents were introduced .Meanwhile ,handling of problems appeared during manufacture and inspection process ,as well as basic situations of the pressure vessels after put into production were explained .These measures ensured the safety of the pressure vessels and the successful start-up of the devices to produce qualified natural gas ,condensate oil and corre-sponding affiliated products .All of above made a breakthrough in the large gas field development both at home and abroad ,and the unit was successfully commissioned abroad .The practices and processing suggestions in the approaches also provided new safe and convenient ways to imple-ment in the development of similar gas field abroad ,and provided references in design and con-struction for similar units .%介绍了三高气田（高H2 S、高CO2、高Cl-）压力容器设计的基本作法，同时对制造检验过程中出现问题的处理和试运投产的基本情况作了说明，确保了压力容器的安全，装置一次投运成功，最终生产出合格的天然气、凝析油、相应附属产品。该压力容器突破了国内外大型气田的开发，在国外一次投产成功，为今后国外三高气田的开发走出了一条安全可靠、便利实施的新路，这些作法和处理意见为同行们今后的设计、施工提供了参考。
