防治油气集输过程中烃类污染的主要途径

烃类是油气田主要的大气污染物，主要来源于油气集输过程中的烃类损耗。降低烃类损耗，回收挥发气体，是减少大气污染的重要途径。孤东油田应用大罐抽气、原油稳定、轻烃回收等工艺对烃类进行回收治理，文章介绍了使用的工艺系统，分析了治理技术的经济效益，得出结论：采用大罐抽气、原油稳定和轻烃回收技术防治油气田烃类污染是可行的，技术成熟，工艺较简单，投资少，见效快，效益明显。在油气田全面推广应用，可以大大降低油气田的烃类污染负荷

Primary Approach to Prevent Hydrocarbon Pollution During Collection and Transportation of Oil and Gas

Hydrocarbon is the primary air pollutant in oil and gas fields,most of which comes from the consuming during collection and transportation of oil and gas.A important approach to decrease air pollution is to reduce consuming hydrocarbon and reusing volatile gas.Processes,such as extracting gas using large container,stabilizing the raw oil,and reusing light hydrocarbon,are taken into effect to handle the problem in oil field of Gudong.This paper introduces the technology system and analyses the economic benefit.It is concluded that the processes mentioned above are feasible,with well-developed technology,relatively simply process,and low investment.The benefit appears rapidly and apparently.If extending them widely to the whole fields of oil and gas,the hydrocarbon pollution can be greatly reduced.
