탑하사호연합참상압공정유관휘발기위고함류화경적반생기（류화경함량56151mg/m3），설치대관추기계통시십분필요적。침대대관추기계통적저압수송특성등기술난점，종설계규모、류정、설비포국급관선안장등방면진행료우화，실현료유관적안전평은밀폐운행。
The associated gas in the atmospheric fixed roof tanks of the Tahe Central Production Facility(CPF)No.4 contains a high level of hydrogen sulphide(at a value of 56151mg/m3),so it needs a gas extraction system installed.In the light of the technical issues of the gas extraction system such as the fluids transportation characters at a low pressure,and in order to make sure the storage tanks operating at a safe,stable and hermetic conditions,this study focuses on the optimization of the design capacity,process flow,facilities configuration, pipeline installation and so on.
