油田伴生气轻烃回收装置工艺设计 Title:ProcessDesignofAssociatedGasRecoveryEquipmentinOilfields Abstract: Inoilfieldoperations,associatedgasisoftenproducedalongwithcrudeoil.However,duetovariouslimitations,suchaslackofinfrastructureandeconomicviability,asignificantportionofthisassociatedgasisflaredintotheatmosphere,resultinginenvironmentalpollutionandthewasteofvaluableenergyresources.Toaddressthisproblem,thedesignofassociatedgasrecoveryequipmentplaysacrucialroleinmaximizingtheutilizationofassociatedgas.Thispaperaimstoprovideanoverviewoftheprocessdesignofassociatedgasrecoveryequipmentinoilfields. Introduction: Theextractionofcrudeoilfromoilfieldsoftenresultsintheproductionofassociatedgas,whichisamixtureofvariouslighthydrocarbons.Traditionally,thisassociatedgashasbeenflaredduetotechnical,economic,andregulatoryconstraints.However,flaringhassignificantnegativeimpactsontheenvironment,suchasthereleaseofgreenhousegasesandairpollutants.Moreover,itrepresentsamissedopportunitytoharnessvaluableenergyresources.Therefore,itisessentialtodevelopeffectiveprocessesandequipmentfortherecoveryandutilizationofassociatedgas. ProcessDesign: Theprocessdesignofassociatedgasrecoveryequipmentinvolvesseveralkeyconsiderations,includinggascomposition,flowrate,pressureconditions,andenvironmentalregulations.Thefollowingstepsareinvolvedintheprocessdesignofsuchequipment: 1.GasCompositionAnalysis:Thefirststepintheprocessdesignistoanalyzethegascompositionoftheassociatedgasstream.Thisinvolvesdeterminingthepercentagesofdifferenthydrocarbonsandimpuritiespresentinthegas,suchasmethane,ethane,propane,butane,nitrogen,sulfurcompounds,andwatervapor.Gascompositionanalysisiscrucialforselectingsuitableseparationandpurificationmethods. 2.Separation:Oncethegascompositionisknown,separationmethodscanbechosentoseparatethegasintodifferentcomponents.Themostcommonseparationtechniquesforassociatedgasrecoveryincludecryogenicdistillation,absorption,adsorption,andmembraneseparation.Thechoiceofseparationmethoddependsonfactorssuchasgascompositi
