Igesi ehlobene ivame ukubhekisela ku-symbiotic yegesi yemvelo namafutha. Ngokusho kombono wokukhiqizwa kwe-hydrocarbon ephilayo, lapho izinto eziphilayo ziguqukela esigabeni sokuvuthwa, ama-hydrocarbon aketshezi nangamagesi akhiqizwa ngesikhathi esifanayo. Amanye aqukethe namagesi angewona ama-hydrocarbon njenge-carbon dioxide, i-nitrogen ne-hydrogen sulfide. Amagesi e-hydrocarbon angagcwalisiwe awavami ukuqukathwa. Ama-hydrocarbon agesi ancibilikiswa kuma-hydrocarbon aketshezi noma akhona engxenyeni engenhla yedamu esimweni sokuvalwa kwegesi.
Ngokusho kombono wokukhiqizwa kwamafutha e-organic, lapho izinto eziphilayo zithuthuka ziye esigabeni sokuvuthwa, ama-hydrocarbon aketshezi kanye nama-hydrocarbon agesi akhiqizwa ngesikhathi esifanayo. I-hydrocarbon egesi, noma encibilikisiwe ku-hydrocarbon ewuketshezi, noma ikhona engxenyeni engenhla yedamu esimweni se-gas cap. Ibonakala ngokuthi okuqukethwe kwezingxenye ezingaphezu kwe-ethane kuphakeme kunokwegesi engahlobene, kanti ezinye ziqukethe namagesi angewona ama-hydrocarbon njenge-carbon dioxide, i-nitrogen kanye ne-hydrogen sulfide, futhi ngokuvamile aqukethe amagesi ambalwa kakhulu e-hydrocarbon angagcwalisiwe. Igesi ehlobene ingasetshenziswa ukukhiqiza igesi kaphethiloli encibilikisiwe, uphethiloli kanye nezinto zokusetshenziswa zamakhemikhali.
Inhloso yokwelashwa kwegesi ehambisanayo ukwelapha igesi ehambisanayo etholakele kanye negesi ezinzile, ukuze kukhiqizwe igesi encibilikisiwe, i-hydrocarbon elula ezinzile kanye negesi eyomile, futhi kuthuthukiswe ukusebenza kahle kokusetshenziswa okuphelele kwemithombo kawoyela negesi. Ukuze kuthuthukiswe izinga lokubuyiselwa kwe-hydrocarbon ekhanyayo yegesi ehambisanayo, inqubo yokwelashwa kwegesi ehambisanayo nayo ishintshwa kusukela enkambisweni yokuhlukaniswa kwe-shallow cold condensation fractionation enomfutho ophakathi kuya enkambisweni yokumuncwa kwe-shallow cold oil enomfutho ophakathi, futhi inqubo yokumuncwa kwe-cold oil ithuthukiswa njalo ukuze kwakhiwe ubuchwepheshe bokugcina umbala bokwelapha igesi ehambisana nensimu kawoyela.
Isigaba I: inqubo yokupholisa okungajulile ngomfutho ophakathi nendawo – indlela yokuhlukanisa i-condensation. Iyunithi yokuqala yokubuyisa i-hydrocarbon ehlanganisiwe yakhiwa esiteshini sokwelapha esiphakathi saseMaling ngo-Okthoba 1981. Icubungula kakhulu igesi ehlobene negesi ezinzile ngaphandle kwesiteshi ukuze ikhiqize igesi encibilikisiwe kanye namafutha okukhanya azinzile. Inqubo yokupholisa okungajulile ngomfutho ophakathi nendawo – indlela yokuhlukanisa i-condensation. Iyunithi yavalwa ngo-1991. Inqubo yokupholisa okungajulile ngomfutho ophakathi nendawo – ukuhlukanisa i-condensation inqubo esetshenziswa kakhulu ekwelapheni igesi ehlobene nensimu kawoyela kanye nokubuyisa i-condensate. Le nqubo isetshenziswa kumayunithi okubuyisa i-hydrocarbon akhanyayo akhiwe ngaphambi kuka-2004.
Isigaba sesibili: inqubo yokupholisa okungajulile ngomfutho ophakathi nendawo - indlela yokumunca uwoyela obandayo. Ngemuva kuka-2004, inqubo yokupholisa okungajulile ngomfutho ophakathi nendawo - indlela yokumunca uwoyela obandayo izothuthukiswa. Yasetshenziswa ngempumelelo kuyunithi yokubuyisa i-hydrocarbon ekhanyayo yesiteshi sokudlulisa imitha i-WANGSHIBA okokuqala, ikakhulukazi iphatha igesi ehlobene ngaphandle kwesiteshi kanye negesi eguquguqukayo evela emathangini kawoyela, futhi ikhiqiza igesi encibilikisiwe kanye nemikhiqizo kawoyela okhanyayo ozinzile. Uma kuqhathaniswa nendlela yokuhlukaniswa kwe-condensation, indlela yokumunca uwoyela obandayo inezici zokukhiqiza okuphezulu kwe-C, inzuzo enhle yezomnotho, ukuzivumelanisa nenqubo ebanzi kanye nokuguquguquka okukhulu kokusebenza. Inqubo yamukelwa kumayunithi alandelayo anegesi ehlobene njengegesi yokuphakelayo.
