Abstract: Currently,the flash gas generated during the operation of existing triethylene glycol （TEG） dehydration units in gas field stations is directly discharged through the venting system,which leads to problems such as environmental pollution and the continuous burning of torch pilot lights. This approach fails to meet relevant requirements such as environmental protection standards,affects the full capacity production and restricts the high-quality development of gas fields. This paper discusses the role of flash gas treatment technologies,including optimization of Kimray pumps and pressurization recovery methods,in the optimization and adjustment of natural gas production and gathering systems,so as to facilitate the achievement of zero emission of flash gas.

Key words: gas field, flash gas, pressurization, treatment
