Incazelo Yemikhiqizo
Imboni yegesi yemvelo ecindezelwe (eyaziwa nangokuthi isitshalo se-CNG) isethi ephelele yemishini ehlanganisa ukuhlanzwa kwegesi yemvelo, ukuminyanisa, nokugcinwa.
Umgomo wayo oyinhloko owokuqala ukuhlanza igesi yemvelo eluhlaza ukuze kukhishwe ukungcola okuyingozi, bese usebenzisa-ama-compressor esiteji ukuze ukhuphule umfutho ube ngu-20-25 MPa, uyiguqule ibe igesi enomfutho ophezulu ongagcinwa kumasilinda noma emathangeni.
Ingakhiqiza ngokuzinzile-i-CNG yekhwalithi ephezulu futhi ingenye yezinto ezisetshenziswa kakhulu igesi yemvelo ekuthuthweni nasezinhlelweni zamandla asabalalisiwe.
Isimiso sokusebenza
Inqubo yokusebenza yesitshalo se-CNG ingafingqwa njengezinyathelo ezinhlanu ezibalulekile: ukugaywa kwegesi eluhlaza → ukucindezelwa → ukuphelelwa amanzi emzimbeni nokukhishwa kwesulfurization → isitoreji → ukuphuma komkhiqizo
Ukwelashwa kwegesi eluhlaza:Igesi yemvelo eluhlaza (imvamisa ku-0.1-1.0 MPa) ingena kusihlukanisi sokuhlunga ukuze isuse izinhlayiya eziqinile, amanzi awuketshezi, namafutha amahhala (ukuvikela ama-compressor angezansi ekugugeni nasekugqwaleni).
Ukuminyanisa:Uphethiloli ocindezelwe ngaphambilini ucindezelwa-ngezigaba eziningi zokuphindaphinda noma i-screw compressor. Isiteji ngasinye sicindezela igesi ku-4-6 MPa, nge-intercoolers phakathi kwezigaba zokunciphisa izinga lokushisa (ukugwema ukushisa nokuthuthukisa ukusebenza kahle kokucindezela), ekugcineni ifinyelele ukucindezela okuhlosiwe kwe-20-25 MPa.
Ukuphelelwa amanzi emzimbeni kanye ne-desulfurization:Igesi elicindezelwe lingena ohlelweni lokuhlanza. Ukuphelelwa amanzi emzimbeni (ukusebenzisa izisefo zamangqamuzana noma okomisa okomisa) kunciphisa okuqukethwe kwamanzi kube ngaphansi kuka-10 ppm (ukuvimbela ukwakheka kwe-hydrate kumapayipi{2}}okucindezela okuphezulu); i-desulfurization (kusetshenziswa i-activated carbon or amine scrubbers) isusa i-hydrogen sulfide ibe ngaphansi kuka-20 mg/Nm³ (ukugwema ukugqwala kwempahla yokugcina nokulimala kwenjini).
Isitoreji:I-Puified high{{0}CNG yokucindezela kwe-CNG igcinwa{1}kumasilinda okugcina ukucindezela okuphezulu noma amathangi, aklanyelwe ukumelana no-20-25 MPa futhi afakwe amavalvu okuphepha nezikali zokucindezela ukuqapha umfutho.
Okukhipha umkhiqizo:I-CNG evela ezikhungweni zokulondoloza isatshalaliswa kubasebenzisi ngesistimu yokukhipha impahla. Ukuze imoto ifake i-refueling, i-dispenser inciphisa ukucindezela ku-20 MPa kanye namamitha wegesi; ukusetshenziswa kwezimboni, ingcindezi ilungiswa ngokuvumelana nezidingo zomsebenzisi ngokusebenzisa izilawuli zengcindezi.
Izici ezibalulekile
Isitoreji esinengcindezi ephezulu
Isebenza ku-20-25 MPa, ivumela ukuncishiswa kwevolumu okusebenzayo ukuze kube lula ukuhamba nokugcinwa, kulungele izimo zokunikezwa kukaphethiloli weselula.
01
Umthamo oguquguqukayo
Umthamo-owodwa wokucubungula wansuku zonke usukela ku-5,000 Nm³ kuya ku-500,000 Nm³, uvumelana nezidingo-ezincane (amagalaji kaphethiloli) kanye-nobukhulu (amapaki ezimboni).
02
Ukufaka uphethiloli okusheshayo
Ifakwe-izikhiqizo ezigeleza eziphezulu ezingafaka uphethiloli emotweni ye-CNG emizuzwini emi-3-5, ehlangabezana nezidingo zamahabhu okuthutha amatasa.
03
Isakhiwo esihlangene
Imishini eyinhloko (ama-compressors, amasilinda okugcina, ama-dispensers) angahlelwa ngendlela ye-modular, ehlala endaweni encane, efanelekile ukuthunyelwa emadolobheni noma emadolobheni.
04
Ukukhishwa okuphansi
I-CNG inokukhishwa kwekhabhoni ephansi kunophethiloli noma udizili (cishe ukuncipha okungama-20-30%), okwenza imboni ibe yinketho yokuphakelwa kwamandla ekhabhoni ephansi.
05
Izinzuzo zemikhiqizo yenkampani yethu
Namuhla, njengoba ukusetshenziswa kwamandla ahlanzekile kuya kwanda, idizayini yobunjiniyela ecolisisiwe ibalulekile ukuze kuzuzwe ukukhiqizwa okuphumelelayo nokuphephile kwezitshalo Zegesi Yemvelo Ecindezelekile. Sisungule ithimba lonjiniyela elineminyaka engaphezu kwengu-25 yokunqwabelana kobuchwepheshe emkhakheni wokucindezelwa kwegesi yemvelo, elikwazi ngokugcwele izindinganiso ezibalulekile zasekhaya nezamazwe ngamazwe kanye nokucaciswa okufana ne-ISO, API, ASME, kanye ne-EN. Ngokusekelwe ezicini zegesi eluhlaza (okuhlanganisa isilinganiso se-methane nokwakheka kokungcola) kanye nezindawo ezisetshenziswayo (isb., ukufaka amafutha emoto noma ukunikezwa kwegesi yezimboni) zamaphrojekthi ahlukene, sinikeza izixazululo zedizayini eziqondene nawe. Sigxila ekuthuthukiseni ukumiswa kwesiteji se-compressor, ukusebenza kahle kwe-intercooler, kanye nokuxhumana kwesistimu yokuhlanza, okunganciphisa ukusetshenziswa kwamandla ngo-5% -8% uma kuqhathaniswa nezikimu ezivamile. Sihlala sinamathela emcabangweni wokwenza ngokwezifiso ukuze siqinisekise ukuthi isitshalo ngasinye sifana ngokunembile nezidingo zaso zokusebenza ezihlukile.
Kuwo wonke umjikelezo ophelele wephrojekthi kusukela ekuhleleni kuya ekusetshenzisweni, inkampani yethu isebenzisa ngokugcwele amazinga e-ISO9001 Quality Management System kanye ne-ISO14001 Environmental Management System. Esigabeni sokuklama kwenqubo, sisebenzisa isofthiwe yobungcweti njenge-Aspen HYSYS yokulingisa isistimu ye-compressor ukuqinisekisa ukuzinza kwengcindezi yayo yokusebenza. Zonke izinto zokusebenza ezingukhiye, okuhlanganisa ama-compressor,{4}amavalvu okucindezela okukhulu, nemithombo yokugcina igesi, zihlolwa izikhungo ezizimele-zezinkampani zangaphandle ukuze kuqinisekiswe ukuthobelana nezimfuneko zokucaciswa kwemishini yokucindezela njenge-ASME BPVC Section VIII. {{7}Imisebenzi yokushisela yamapayipi anomfutho ophakeme isebenzisa ngokuqinile izinqubo zenqubo eqinisekisiwe, ehlanganiswe- nezindlela zokuhlola ezingabhubhi ezifana ne-Ultrasonic Testing (UT) kanye ne-Penetrant Testing (PT), okuqinisekisa ngempumelelo ukuthembeka kokuvala amalunga. Ukuhlolwa kokuzinza okuqhubekayo kwamahora angu-72 kwenziwa ngaphambi kokuqedwa kwephrojekthi ukuze kuqinisekiswe ngokugcwele ukusebenza kwedivayisi mayelana nokugeleza kokucubungula, ingcindezi yesistimu, nobumsulwa begesi. Leli sethi eliphelele lezinqubo ezijwayelekile linikeza isiqinisekiso esiqinile sokuthembeka kwekhwalithi yephrojekthi kanye nesikhathi sokulethwa.
Izinga lomkhiqizo liyisisekelo esiyisisekelo sokuqinisekisa ukuhlinzekwa okuphephile nokuzinzile kwe-CNG. Isitshalo ngasinye sisebenzisa izindinganiso eziqinile zokulawula ikhwalithi: isistimu ye-compressor ifakwe izivikelo eziningi zokugcwala ngokweqile kanye{1}}nokuqapha kwangempela kwezinga lokushisa kwesikhathi ukuze kuqinisekiswe ukusebenza okuqhubekayo nokuthembekile; amayunithi okugcina igesi enomfutho ophezulu{{2}ekhiqizwa ngokuhambisana ngokuqinile ne-GB 150 noma imininingwane ye-ASME nempilo yesevisi engengaphansi kweminyaka engu-20; idivayisi yokuhlanza igesi iqinisekisa ukuthi i-CNG ekhiqiziwe ihlangabezana ngokugcwele nezidingo zamazinga kazwelonke afana ne-GB 18047, futhi izinga lokufaneleka komkhiqizo lihlala ligcina i-100%. Isilinganiso senkinga{8}isikhathi sokusebenza samahhala sayo yonke isethi yezisetshenziswa sidlula amahora angu-8000, sinikeza usekelo oluqinile{10}}lokusebenza kahle kwesikhathi eside.
Ukuqinisekisa ukunikezwa okuqhubekayo nokuzinzile kwe-CNG, ikhwalithi ephezulu-ngemuva{1}}yesevisi yokuthengisa ibalulekile. Ngemva kokuthola isicelo sesevisi esivela kumsebenzisi, ithimba lethu losekelo lobuchwepheshe lizokwenza kusebenze indlela yokuphendula 24/7 ngokushesha futhi lithembise ukunikeza impendulo yokuqala phakathi namahora angu-8 ngezingcingo, ama-imeyili, noma{6}}ezinhlolovo zesayithi. Ezindabeni ezixazululeka ukude ezifana nokulungiswa kwengcindezi nokuxilongwa kwe-alamu, siyaqinisekisa ukusiza ekuqedeleni umsebenzi phakathi namahora angu-24; uma kuba nokwehluleka kwemishini okudinga{9}}ukulungiswa kwesayithi, onjiniyela bangathunyelwa ezindaweni zasekhaya phakathi namahora angu-48 nasezindaweni zamazwe ngamazwe phakathi namahora angu-72. Ngaphezu kwalokho, sihlinzeka ngezinsizakalo zokulungisa ezihleliwe ezihlanganisa ukushintshwa kukawoyela we-compressor kanye nokuhlanza izihlungi ukuze kunwetshwe ngempumelelo impilo yesevisi yemishini.
Izitshalo zethu Zegesi Yemvelo Ecindezelwe zibonise ukwethembeka nokusebenza kahle kakhulu-ezinhlelweni zokusebenza zezimboni ezinkulu, futhi ziye zaqashelwa amabhizinisi amaningi ahamba phambili ezimbonini zamandla nezokuthutha, okuhlanganisa nezinkampani ezaziwayo emhlabeni wonke njengePetroChina, iSinopec, iGazprom, nezinkampani zikaphethiloli wamandla ahlanzekile.
Ngokwezindlela zokubambisana, asihlinzeki kuphela-isixazululo esigcwele sokulethwa kwe-turnkey esihlanganisa ukuklama, ukufakwa, nokusebenzisa kodwa futhi sinikeza amamodeli aguqukayo afana nokuqashiswa kwemishini noma izivumelwano zokuhlinzeka ngegesi (sibophezelekile ngokusebenza kwemishini nokuhlinzeka nge-CNG kumakhasimende) ngokuvumelana nezidingo zangempela zamakhasimende, ukusiza amakhasimende akhethe uhlelo lokutshala izimali olufaneleka kakhulu ezimweni zawo.
