I-CNG Gas Production Plant

Imboni yokukhiqiza igesi ye-CNG (eyaziwa nangokuthi imishini yokukhiqiza ye-CNG) iyisethi ephelele yemishini ehlanganisa ukuhlanzwa kwegesi yemvelo, ukucindezelwa, nokugcinwa.

 

Umgomo wayo oyinhloko ukusebenzisa ukwehlukana ngokomzimba kanye-nobuchwepheshe bokucindezela kwezigaba eziningi: okokuqala, ukususa ukungcola okuyingozi egesini yemvelo eluhlaza ukuze kuqinisekiswe ukuphepha kwezinqubo ezilandelayo; bese, ngokuminyanisa{1}izigaba eziningi, kwenyusa umfutho wegesi ukuya ku-20-25 MPa, wehlise ivolumu ngo-1/200 ukuze kuzuzwe ukugcinwa nokuthutha okuphumelelayo.

 

Ingakhiqiza ngokuzinzile-i-CNG yekhwalithi ephezulu futhi ingenye yezinto ezisetshenziswa kakhulu igesi yemvelo ekuthuthweni nasezinhlelweni zamandla asabalalisiwe.

Inqubo yokusebenza Yesikhungo Sokukhiqiza i-CNG ingafingqwa njengezinyathelo ezinhlanu ezibalulekile: ukuhlungwa kwegesi eluhlaza → ukuhlanzwa (ukukhipha amanzi emzimbeni nokukhishwa kwesulfurization) → -ukucindezelwa kwesiteji → ukuqiniswa kwengcindezi nokugcinwa → ukuphuma komkhiqizo

Esimweni sokusheshisa ukuthuthukiswa kwamandla ahlanzekile, izixazululo zobunjiniyela obucwengekile ziyisici esibalulekile sokuqinisekisa ukusebenza kahle nokuphephile kwezitshalo zokukhiqiza igesi ye-CNG. Inkampani yethu isungule ithimba lochwepheshe bezobuchwepheshe, amalungu alo wonke aneminyaka engaphezu kwengama-20 yokuhlangenwe nakho okungokoqobo emkhakheni wokucindezelwa kwegesi yemvelo nokuhlanzwa, futhi anolwazi emibhalweni eminingi ebalulekile yasekhaya neyamazwe ngamazwe njenge-GB, ISO, ASME, kanye ne-EN. Ngokusekelwe ezicini zegesi eluhlaza (okuhlanganisa nokuqukethwe kwe-methane nokwakheka kokungcola) kwamaphrojekthi ahlukene nezinkomba ezithile zamakhasimende (njengokucindezela kokuphumayo okuqondiwe nesikali sokucubungula sansuku zonke), sihlinzeka ngezixazululo zokwakheka komuntu siqu. Sigxila ekulungiseleleni ukulungiselelwa kwesiteji-se-compressor, ukuhlanganiswa kweyunithi yokuhlanza, nokusebenzisa kahle ukushisa kukadoti, okunganciphisa ukusetshenziswa kwamandla ngo-5%-8% uma kuqhathaniswa nemiklamo evamile. Sihlala sinamathela emcabangweni wokwenza ngokwezifiso, senza ukuthuthukiswa okujulile kwephrojekthi ngayinye, futhi siqinisekisa ukuthi uhlelo luhlangabezana ngokuphelele nezimo zangempela zohlelo lokusebenza.

Kuyo yonke inqubo ephelele yephrojekthi kusukela ekuqalisweni kuya ekulethweni, sizisebenzisa ngokugcwele izidingo ze-ISO9001 Quality Management System, esebenza kuzo zonke izixhumanisi zokuklama izikimu, ukuthengwa kwezinto ezibonakalayo, ukukhiqizwa kwemishini, kanye nokugunyazwa kwesistimu. Esigabeni sokuklama kwenqubo, amathuluzi okulingisa angochwepheshe afana ne-HYSYS asetshenziselwa ukulingisa nokuqinisekisa ukusebenza kahle kokucindezelwa kanye nokusebenza kokuhlanza; ezingxenyeni eziyinhloko ezifana nama-compressor,{2}}amavalvu okucindezela okukhulu, nezisefo zamamolekyuli, izinqubo zokuhlola ezingenayo eziqinile ziyasetshenziswa ukuze kuqinisekiswe ukuthi zihlangabezana ngokugcwele nezicaciso zobuchwepheshe; phakathi nesigaba sokukhiqiza nokukhiqiza, kulandelwa izinqubo ezijwayelekile zokusebenza (ama-SOP), nezindlela eziningi zokuhlola{3}}ezingonakalisi njenge-UT ne-RT zenziwa ezingxenyeni zokushisela ezibalulekile njengamapayipi{4}}okucindezela okukhulu; ngaphambi kokulethwa, isethi ngayinye yezisetshenziswa kufanele iphumelele ukuhlolwa kokuzinza okungaphazamiseki okungamahora angama-72 ukuze kuqinisekiswe ngokugcwele umthamo wayo, ukuhlanzeka komkhiqizo, namandla okulawula ingcindezi. Ngokusebenzisa le modeli yokulawula ehlelekile, siqinisekisa ngempumelelo ukuzinza nokuthembeka kwekhwalithi yomkhiqizo.

Sigxila ekunikezeni amakhasimende{0}}izinto zokusebenza zokukhiqiza ze-CNG eziphezulu. Ukuphathwa kwekhwalithi okuqinile kusetshenziswa ohlelweni ngalunye ngesikhathi sokukhiqiza: i-compressor ihlanganisa ukuqapha okuhlakaniphile nemisebenzi yokulawula ukuze kuqinisekiswe ukusebenza okuqhubekayo nokuzinzile; iyunithi{{2}ephezulu yengcindezi yokulondoloza kanye neyokuthutha yenziwe ngezinto{3}}ezinamandla aphezulu njenge-34CrMo4 nempilo yesevisi yokuklama engengaphansi kweminyaka engama-20; idivayisi yokucubungula igesi iqinisekisa ukuthi i-CNG ekhiqiziwe ihlangabezana ngokugcwele namazinga kazwelonke afana ne-GB 18047, futhi izinga lokufaneleka lomkhiqizo ligcina u-100% ngokungaguquki. Izinkinga ezimaphakathi{10}}zesikhathi sokusebenza samahhala sawo wonke umshini singafinyelela amahora angaphezu kuka-10,000, sinikeze isiqinisekiso esiqinile sokukhiqiza{13}}kwamakhasimende isikhathi eside okuzinzile.

-Ikhwalithi ephezulu futhi ephumelelayo-ukwesekwa kokuthengisa kuyisici esibalulekile sokuqinisekisa-ukusebenza okuzinzile kwesikhathi eside kwezisetshenziswa. Lapho lithola isicelo sesevisi yekhasimende, ithimba lesevisi yezobuchwepheshe lizonikeza impendulo esheshayo engu-24/7 futhi linikeze iziphakamiso zokusingatha kuqala phakathi namahora angu-8 ngezingcingo, impendulo ye-imeyili, noma izinkomfa zevidiyo. Ngamaphutha angaxazululwa ngokusebenza okukude njengokwenza kahle ipharamitha kanye nokucutshungulwa kolwazi lwe-alamu, abasebenzi bezobuchwepheshe bazoqondisa abasebenzisi ukuthi baqedele indawo yenkinga futhi balungise phakathi namahora angu-24; uma inkinga idinga{9}}ukulahlwa kwesayithi, abasebenzisi basekhaya bazothola{10}}onjiniyela besevisi yesayithi phakathi namahora angu-48 ngemva kokuqinisekiswa kwephutha, kanye nabasebenzisi bamazwe ngamazwe phakathi namahora angu-72. Ngaphezu kwalokho, sihlinzeka ngezinsizakalo zokulungisa zokuvimbela ngezikhathi ezithile, okuhlanganisa{14}}ukulungiswa okujulile kwe-compressor kanye nokushintshwa okujwayelekile kwe-adsorbent, ukuze kunwetshwe ngempumelelo iyonke impilo yesevisi yesisetshenziswa.

Imboni yethu yokukhiqiza igesi ye-CNG izuze ukwethenjwa amabhizinisi amaningi ahamba phambili ezimbonini zamandla nezokuthutha ngokusebenza okuthembekile nokusebenza kahle kakhulu kokukhiqiza, okuhlanganisa nezinkampani ezidumile emhlabeni wonke njengeSinopec, PetroChina, TotalEnergies, nezinkampani zamandla ahlanzekile.

Mayelana nokunikezwa kwemishini, asihlinzeki nje kuphela ngesixazululo sokulethwa kwe-turnkey esimboza ukuklama, ukukhiqiza, nokufakwa kodwa futhi sinikeza amamodeli wokubambisana ahlukahlukene njengokuqashisa imishini nokusebenza nokuphathwa kokugcinwa kokunakekelwa ngokwezidingo zamakhasimende, esiza amakhasimende ngokuguquguquka ukukhetha uhlelo olufanele kakhulu lokubambisana olusekelwe ezidingweni zangempela kanye nesabelomali sokutshala izimali.
