摘　　要：LG气田含硫气田水闪蒸气通过站场低压放空管线接入火炬,利用放空火炬的长明火将其燃烧,会产生CH_(4)、CO_(2)、SO_(2)等温室气体和大气污染物。为了有效应对全球气候变化、实现温室气体净零泄放,对现有含硫闪蒸气泄放工艺进行技术改造,采用智能电动球阀定压间歇泄放自动点火燃烧技术熄灭该气田采集气站场放空火炬的长明火。现场应用表明其CH4管控率可达85.5%以上,节省燃料气费用662.7万元/a,有效减少了LG气田含硫气田水闪蒸气和燃料气的CH4泄放量及燃料气的消耗量,显著提高了LG气田的CH4管控水平,环保、经济效益凸显。The flash vapor of the sulfur-containing gas field water in LG gas field is connected to the flare through the low-pressure venting pipeline of the station.Burning it with the long open flame of the venting flare will produce greenhouse gases such as methane,carbon dioxide,sulfur dioxide,and atmospheric pollutants.In order to effectively respond to global climate change and achieve net zero release of greenhouse gas,it is necessary to carry out technological transformation of the existing sulfur-containing flash gas release process.Intelligent electric ball valve constant pressure intermittent release automatic ignition combustion technology was used to extinguish the open flame of the venting flare in the gas field collection station.Field applications showed that its methane control rate could reach over 85.5%,saving fuel gas costs of 6.627 million yuan per year.This effectively reduced the methane release and fuel gas consumption of sulfur-containing gas field water flash vapor and fuel gas in the LG gas field,and significantly improved the methane control level of the LG gas field.Environmental protection and economic benefits were highlighted.
