Ukwelashwa kwethu kwegesi yomsila engu-120 million Nm3/d kanye nephakheji yokubuyisa i-LPG sekuyasebenza kahle manje edolobheni laseGuizou eShayina
Ukwelashwa kokukhishwa kwegesi yemvelo iyingxenye ebalulekile yemboni yegesi yemvelo, ehlose ukunciphisa ukukhishwa kwezinto eziyingozi kugesi yokukhipha ugesi, ukuvikela imvelo kanye nempilo yabantu. Isitshalo sokuhlanza igesi yemvelo sisebenzisa ubuchwepheshe obuthuthukisiwe bokwelapha igesi yomsila ukuqinisekisa ukuthi izinto ezinobuthi neziyingozi kugesi yomsila zikhishwa ngokuphelele ngaphambi kokuba zikhishwe, ukuze kuhlangatshezwane nezindinganiso zokukhishwa kokungcola nokugwema ukungcola komoya. Nazi ezinye izindlela ezibalulekile zokucubungula kanye nezicelo zobuchwepheshe.
Isimiso sokulawula kanye nokusetshenziswa kwesishisi segesi yomsila: Enqubweni yokwelapha igesi yomsila yezitshalo zokuhlanza igesi yemvelo, isishisi segesi yomsila siyithuluzi elibalulekile, umsebenzi walo oyinhloko ukuxubha ngokuphelele izinto ezinobuthi neziyingozi ezisele kugesi yomsila ngaphambi kokukhishwa. Ngokuthatha izinyathelo eziningana, njengokushintsha isibhamu sokushisa ngokunemba okuphezulu kokuthola ilangabi, ukwandisa izinga lokugeleza kwegesi yokuvikela ukupholisa, kanye nokususa umoya ohlangothini lwesishisi somshayeli, impilo yesevisi yesishisi somshayeli ithuthukisiwe kakhulu, okuqinisekisa ukusebenza okuzinzile kwesishisi somshayeli somsila.
Iphrojekthi yokuvuselelwa kwegesi yomsila: Ukuze kuncishiswe kakhulu ukukhishwa kwezinto eziyingozi kugesi yomsila, iMoxi Natural Gas Purification Plant yenze iphrojekthi yokuvuselelwa kwegesi yomsila yeyunithi yokubuyisa isibabule. Le phrojekthi ihlose ukunciphisa ukugcwala kokukhishwa kwe-sulfur dioxide kusuka kugesi yokukhipha umoya futhi inikeze isiqinisekiso sokuhlinzekwa kwegesi yemvelo ebusika esifundeni. Iphrojekthi yaqedwa futhi yaqala ukusebenza, okubonisa ukubaluleka okuhlobene nokuvikelwa kwemvelo kanye nempilo yomphakathi.
Ukucubungula igesi yemvelo inqubo yokususa umhwamuko wamanzi, i-hydrogen sulfide, i-mercaptan, kanye ne-carbon dioxide kugesi yemvelo. Imishini eyinhloko ihlanganisa iyunithi yokuphelelwa amanzi emzimbeni, iyunithi yokususa i-sulfurization, iyunithi yokususa i-carbonization, futhi ukubuyiselwa kwe-hydrocarbon elula iyunithi.
Ukubuyiswa kwe-hydrocarbon elula kubhekisela enkambisweni yokubuyiswa kwezingxenye ezisindayo zegesi yemvelo, njenge-methane noma i-ethane, ngesimo soketshezi. Phakathi kwazo, ingxube ye-propane butane iba yigesi kaphethiloli encibilikisiwe (i-LPG), kanti i-pentane nezingxenye zayo ezingenhla ziba uwoyela olula. Ukubuyiswa kwe-hydrocarbon elula ngokuvamile kusebenzisa ukugcinwa kwe-propane kanye nokugcinwa okuxubile ukuze kufezwe ukusebenza okuhlukile kokubuyiselwa.
Iphrojekthi: Isitshalo Sokuhlanza Igesi Yemvelo saseJiulongshan, idolobha laseGuizhou, eShayina
Isikali somklamo: Idivayisi yokwelapha igesi yomsila engu-120 Nm3/d isetshenziswa kakhulu ukwelapha igesi yomsila kaClaus yeyunithi yokutakula i-sulfur, kanye negesi engcolile yedamu le-sulfur eliwuketshezi yeyunithi yokutakula i-sulfur kanye negesi engcolile ye-TEG yeyunithi yokudambisa amanzi emzimbeni.
Ngemva kokwelashwa, igesi yomsila ingafinyelela ku-400mg/Nm3.
Isikhathi sokukhiqiza saminyaka yonke sale divayisi singamahora angu-8000,
Ukuguquguquka kokusebenza: 50% -120%.
Umthamo wokucubungula:
Igesi yokukhipha ugesi kaClaus ingu-48.8132 kmol/h,
Igesi yokukhipha i-TEG ingu-2.2197 kmol/h,
Igesi yokukhipha amanzi echibini lesulfure elinguketshezi ingu-0.7682 kmol/h.
