LNG加气站供销差产生原因分析与管控杨宇栗1刘强2李剑11.内蒙古华油天然气有限责任公司阿拉善左旗分公司2.包头市燃气热力管理处摘要:目的供销差一直是LNG加气站管控的难点,降低LNG加气站供销差,特别是低效LNG加气站的供销差,对于成本控制具有重要意义。方法根据场站实际生产运营情况,从上游计量、销售计量、贸易采购、卸车工艺和储存等方面,全面分析LNG加气站供销差产生的具体原因。对影响加气站供销差较大的一些因素如气源采购、工艺管道设计、绝热保冷施工、潜液泵安装、储罐放散控制和建站方式等针对性地采取管控措施。结果通过工艺改造后的实践数据测定、生产运行的精细化管理,有效降低了LNG加气站的供销差。结论LNG加气站在初始设计和实际运营管理阶段,应根据LNG物性特点,确定场站建设标准和加强管控以降低供销差,从而提高LNG加气站利润。关键词:LNG加气站;供销差;原因分析;管控措施DOI:10.3969/j.issn.1007-3426.2023.04.010引用格式:杨宇栗,刘强,李剑.LNG加气站供销差产生原因分析与管控[J].石油与天然气化工,2023,52(4):61-65.YANGYL,LIUQ,LIJ.CauseanalysisandcontrolofsupplyandsalesdifferenceinLNGfillingstations[J].ChemicalEngineeringofOil&Gas,2023,52(4):61-65.CauseanalysisandcontrolofsupplyandsalesdifferenceinLNGfillingstationsYangYuli1,LiuQiang2,LiJian11.InnerMongoliaHuayouNaturalGasCo.,Ltd.AzuoqiBranch,Alxa,InnerMongolia,China;2.BaotouGasandHeatManagementOffice,Baotou,InnerMongolia,ChinaAbstract:ObjectiveThesupplyandsalesdifferencehasalwaysbeenakeypointinthemanagementandcontrolofLNGfillingstations.ReducingthesupplyandsalesdifferenceofLNGfillingstations,especiallyinefficientLNGfillingstations,isofgreatsignificanceforcostcontrol.MethodsAccordingtotheactualproductionandoperationstatusofthestation,thespecificreasonsforthesupplyandsalesdifferenceofLNGfillingstationsarecomprehensivelyanalyzedfromtheaspectsofsalesmeasurement,tradeprocurement,unloadingprocessandstorage.Forsomefactorsthatenlargingsupplyandsalesdifference,thetargetedcontrolmeasuresshallbetakenfromtheaspectsofgassourceprocurement,processpipelinedesign,thermalinsulationconstruction,submersiblepumpinstallation,tankreleasecontrolandstationconstructionmode,etc.ResultsThroughthemea...
