为确保重庆市境内大天池气田的天然气集输工程安全可靠地输送含硫天然气 ,川东开发公司在气田上普遍采用三甘醇 (TEG)脱除进入集输管线的含硫天然气中的水分 ,以实现干含硫气输送。文章介绍具有代表性的安装在天东 9井的 1 0 0× 1 0 4 m3/d引进橇装TEG脱水装置的情况 ,包括装置橇块构成、工艺流程、主要工艺设备和实际运行参数等 ,其中列出了冬、夏干气露点控制 ,TEG浓度、TEG循环量等参数 ,并介绍了自动调节回路和联锁回路。最后 ,对实际运行中出现的问题进行了分析 ,并针对存在问题提出了建议。
In order to ensure the safe and reliable delivery of natural gas to natural gas in the large Tianchi gas field in Chongqing Municipality, Chuandong Development Company commonly uses TEG to remove moisture from natural gas entering the gas gathering and gathering pipelines, In order to achieve dry gas delivery. The article introduces the introduction of a skid-mounted TEG dewatering device, which is installed in a well of Tiandong 9 well, including the structure of the skid block, the process flow, the main process equipment and the actual operating parameters. It lists the winter and summer dry gas dew point control, TEG concentration, TEG circulation and other parameters, and introduced the automatic adjustment circuit and interlock circuit. Finally, the problems in the actual operation are analyzed and suggestions are put forward for the existing problems.
