文档介绍：Selexol脱碳工艺的参数优化及适应性研究张哲1皮艳慧2陈思锭2(;)摘要:对于高含碳、微含H2S的特殊天然气气藏,Selexol脱碳工艺因其溶剂绿色环保、腐蚀性小而受到了越来越多的关注与研究。利用HYSYS2006软件优化Selexol工艺的吸收塔控制参数以及闪蒸再生条件,进一步体现Selexol工艺的适应性。结果表明:吸收塔操作条件为原料气入塔温度-5~5℃,贫液注入量750m3/h左右,注入温度越低越佳,实际运行中不得低于-18℃。闪蒸再生时,优化的三级压力分别为2400kPa、500kPa和50kPa。Selexol工艺适用于CO2含量在60%以下,C4+重烃小于1%(V)的贫天然气脱碳处理。关键词:高含碳天然气,Selexol,脱碳,优化,适应性文献标识码:ATheProcessParameterOptimizationandAdaptiveResearchofSelexoldecarburizationZhangZhe1,PiYanhui2,ChenSiding2(&EngineeringInstitute,Beijing,100083;StateKeyLaboratoryofSouthwestPetroleumUniversity,Chengdu,610500)Abstract:InviewofspecialgasreservoirsofhighcarbonandmicrocontainingofH2S,,-5to5°C,poorliquidinjectionrateisabout750m3/h,thelowerofinjectiontemperaturethebetter,injectiontemperatureintheactualoperationshallnotbelowerthan-18°,%andC4+heavyhydrocarbonsislessthan
