摘要
Abstract
This study investigates the VOCs emission characteristics at six typical oil and gas gathering and transportation stations in an oilfield.Emission concentration monitoring was conducted at the station boundaries,and component analysis was performed on the emission sources.The results show that the primary emission sources at oil and gas gathering stations are the open liquid surfaces of storage tanks,wastewater collection and treatment systems,as well as loading/unloading points and dynamic/static sealing points.The VOCs component composition in both oil and gas fields is similar,predominantly consisting of alkanes,which account for an average of 82.18%.Aromatic hydrocarbons follow with an average proportion of 10.63%,while the remaining compounds are olefins(2.08%),halogenated hydrocarbons(4.57%),and oxygenated organic compounds(0.7%).In the oilfield,the alkanes are mainly in the range of C4 to C12,with significant components including n-octane,methylcyclohexane,n-heptane,undecane,decane,n-nonane,and n-hexane.In the gas field,the alkanes are mainly in the range of C2 to C7,with significant components including isobutane,propane,methylcyclohexane,n-pentane,and ethane.The aromatic hydrocarbons in both oil and gas fields are predominantly benzene,toluene,and xylene.关键词
