Incazelo Yemikhiqizo
Iplanti yegesi yemvelo ewuketshezi (eyaziwa nangokuthi isitshalo se-LNG) iyisethi enkulu-yesikali esiphelele sezinto zokusebenza ezihlanganisa ukuhlanzwa kwegesi yemvelo kanye ne-cryogenic liquefaction.
Umgomo wayo oyinhloko owokuqala ukususa ukungcola (amanzi, i-carbon dioxide, izinhlanganisela zesulfure, ama-hydrocarbon asindayo) kusuka kugesi yemvelo eluhlaza, bese apholisa igesi ehlanzekile ibe cishe -ku-162℃ngokusebenzisa isistimu yesiqandisi enezigaba eziningi ukuze iguqule ibe uketshezi, kwehliswe umthamo wayo cishe izikhathi ezingu-600 ukuze igcinwe kahle futhi ihanjiswe.
Ingakhiqiza ngokuzinzile-i-LNG ehlanzekile futhi iyisisetshenziswa esiyinhloko sokuhwebelana kwegesi yemvelo.
Isimiso sokusebenza
Inqubo yokusebenza Yesizinda Sokuxutshwa Kwegesi Yemvelo ingafingqwa njengezinyathelo eziyisikhombisa ezibalulekile: ukucindezelwa kwegesi eluhlaza → ukwelashwa kusengaphambili (ukukhipha amanzi emzimbeni, ukukhishwa kwesulfurization) → ukususwa kwe-hydrocarbon esindayo → ukususwa kwe-mercury → uketshezi olukhalayo → isitoreji se-LNG → ukuphuma komkhiqizo
Ukucindezelwa kwegesi eluhlaza:Igesi yemvelo eluhlaza (imvamisa ku-0.5-5.0 MPa) icindezelwa ku-4.0-7.0 MPa nge-compressor, ihlinzeka ngezimo zengcindezi zokuhlanzwa okulandelayo kanye nokuncibilika.
Ukwelashwa kwangaphambili (ukuphelelwa amanzi emzimbeni, ukuchithwa kwe-sulfurization):Igesi eluhlaza ecindezelwe ingena ohlelweni lokwelashwa ngaphambi kwesikhathi. Ukuphelelwa amanzi emzimbeni (ukusebenzisa izisefo zamangqamuzana) kunciphisa okuqukethwe kwamanzi kube ngaphansi kwe-1 ppm (ukugwema ukwakheka kweqhwa ngesikhathi sokuncibilika); i-desulfurization (ukusebenzisa ukumuncwa kwe-amine noma i-adsorption) kususa i-hydrogen sulfide nesibabule esiphilayo, kwehlisa isamba sesibabule sibe ngaphansi kuka-50 ppm (ukuvimbela ukugqwala kwemishini kanye nobuthi be-catalyst).
Ukususwa kwe-hydrocarbon enzima:Igesi efakwe ngaphambilini ingena embhoshongweni wokuhlukanisa ukuze ihlukanise ama-hydrocarbon asindayo (i-ethane, i-propane, i-butane, njll.) ngomehluko wamaphuzu abilayo, iqinisekisa ukuthi okuqukethwe kwe-hydrocarbon esindayo kugesi yokuphakelayo kungaphansi kuka-0.1% (ukugwema ukuqiniswa ngesikhathi soketshezi).
Ukususwa kwe-Mercury:Igesi igeleza kumbhoshongo we-mercury adsorption (ogcwele isulfur-ikhabhoni efakwe ku-impregnated) ukuze kwehliswe okuqukethwe kwe-mercury kube ngaphansi kuka-0.01 ug/Nm³ (ukuvimbela ukugqwala kwezishintshi zokushisa ze-aluminium alloy).
I-Cryogenic liquefaction:Igesi yemvelo ehlanziwe ingena ohlelweni lokuncibilika (ubuchwepheshe obujwayelekile buhlanganisa i-C3/MRC, AP-X, noma umjikelezo wesiqandisi oxubile). Ishintshana nokushisa ngesiqandisi-esiqandisi sezingxenye eziningi (esakhiwe i-nitrogen, i-methane, i-ethane, i-propane, njll.) ochungechungeni lokushintshisana kokushisa, kancane kancane liphole lisuka kuzinga lokushisa elizungezile liye ku- -162℃, liguqule lisuka kugesi liye ku-LNG ewuketshezi.
Isitoreji se-LNG:Igesi yemvelo ewuketshezi igcinwa emathangini okugcina e-cryogenic avaleleke (ku- -162℃futhi eduze nomfutho womoya) ukuze kuncishiswe ukulahlekelwa ukuhwamuka.
Okukhipha umkhiqizo:I-LNG impontshwa isuka emathangini okugcina iye eziteshini zokulayisha, bese ilayishwa ezithwali ze-LNG noma emalolini amathangi ukuze zihanjiswe. Igesi ehwamukayo (i-BOG, bilisela-igesi) kwinqubo yokubeka iyatholwa futhi iyacindezelwa ukuze iphinde isetshenziswe ohlelweni lokuncibilika noma njengophethiloli.
Izici ze-Liquefied Natural Gas Plant Core
Ukuhlanzeka okuphezulu
Ingakwazi ukukhiqiza i-LNG ngokuzinzile ngokuqukethwe kwe-methane Okukhulu noma okulingana no-99.0%, ngokuqukethwe kokungcola okuphansi (i-nitrogen Ngaphansi noma elingana no-0.5%, i-carbon dioxide Engaphansi noma elingana no-50 ppm) ehlangabezana nezindinganiso zamazwe ngamazwe njenge-EN 1160 ne-GB/T 19204.
01
Umthamo omkhulu wokukhiqiza
Umthamo wonyaka wokukhiqiza wesitshalo esisodwa usukela kumathani angu-50,000 kuya ku-10,000,000, afanele kokubili ukunikezwa kwesifunda kanye nezimo zohwebo zomhlaba.
02
Ukulahleka kokuhwamuka okuphansi
Ubuchwepheshe be-insulation obuthuthukisiwe kanye nezinhlelo zokubuyisela i-BOG ziqinisekisa ukulahlekelwa kokuhwamuka kwesitoreji Ngaphansi noma okulingana no-0.15% ngosuku, kunciphisa ukuchithwa kwamandla.
03
Ukususwa kokungcola okuphelele
Izinqubo eziningi-zokuhlanza isiteji zisusa konke ukungcola okuyingozi, iqinisekisa ukuthi i-LNG{1}ayigqwali futhi ifanele{2}ukugcinwa nokuthutha isikhathi eside.
04
Umjikelezo wokusebenza omude
Uma isizinzile, isitshalo singasebenza ngokuqhubekayo iminyaka engu-2-3, ngokuvalwa okuhleliwe kokugcinwa kwezinto ezibalulekile ezifana nama-compressor nama-heaters.
05
Izinzuzo zemikhiqizo yenkampani yethu
Kumongo wokuhwebelana kwamandla embulunga yonke, idizayini ecolisisiwe ibalulekile ekuqinisekiseni ukusebenza kahle kwezitshalo ze-LNG, ukuphepha, -nokusebenza ngempumelelo kwezindleko. Inkampani yethu inethimba lonjiniyela abaneminyaka engaphezu kwengama-30 yokuhlangenwe nakho kwe-cryogenic liquefaction, ejwayelene namazinga omhlaba afana ne-API, ASME, ISO, kanye ne-EN. Senza ngendlela oyifisayo amadizayini ngokusekelwe ekwakhekeni kwegesi eluhlaza (isb., okuqukethwe kwe-methane, izinhlobo zokungcola) nesikali sokukhiqiza, sithuthukisa amapharamitha omjikelezo wesiqandisi, amanethiwekhi esishintshisi sokushisa, namasistimu okuthola kabusha e-BOG ukuze sizuze ukusetshenziswa okuthile kwamandla Okungaphansi noma okulingana no-0.3 kWh/Nm³ (okungaphansi kwesilinganiso somkhakha). Sigwema izifanekiso ezijwayelekile, siqinisekisa ukuthi isitshalo ngasinye sizivumelanisa nezimo ezihlukile zokuphakelayo kanye nezidingo zokuphumayo.
Inkampani yethu isebenzisa ngokuqinile uhlelo lokuphatha ikhwalithi ye-ISO9001 kanye namazinga okuphathwa kwekhabhoni e-ISO14064 kuwo wonke umjikelezo wephrojekthi, ohlanganisa ukwakheka, ukuthengwa kwempahla, ukwakhiwa, kanye nokugunyazwa. Ngesikhathi sokuklama, ukulingisa kwenqubo kuqinisekisa ukusebenza kahle kwe-liquefaction kanye nemingcele yokuphepha; okokusebenza okubalulekile (izimpindezi, izishintshisi zokushisa ze-cryogenic, amathangi okugcina) zihlolwa{3}}nomuntu wesithathu (okuhlanganisa nokuhlolwa kwengcindezi nokutholwa kokuvuza); ukwakhiwa kulandela izinqubo zokushisela eziqinile zamapayipi e-cryogenic (ngokuhlolwa kwe-UT/RT); ukugunyazwa kubandakanya -amahora angu-100 wokusebenza okuqhubekayo ukuze kuqinisekiswe ubumsulwa be-LNG, umthamo wokukhiqiza, nokusetshenziswa kwamandla. Le ndlela ehlelekile iqinisekisa ukulethwa ngesikhathi kanye nokuhambisana nezinkomba zokuklama.
Sibheka ikhwalithi yomkhiqizo njengesisekelo sokukhiqizwa kwe-LNG ephephile. Isitshalo ngasinye sithola ukulawulwa kwekhwalithi okuqinile: izinto ezisetshenziswayo ze-cryogenic (isb., 304L insimbi engagqwali, i-aluminium alloy 5083) zihlangabezana nezidingo-zokuqina kwezinga lokushisa eliphansi (ukuhlolwa komthelela Okukhulu noma okulingana no-27 J -ku-196℃); izingxenye ezibalulekile (ama-compressor, ama-valve) atholakala ezinkampanini eziphezulu zamazwe ngamazwe anempilo yesevisi Emikhulu noma elingana neminyaka engama-20; imboni ithola izinga lempumelelo yokuqala engu-100% kanye nezinga lokusebenza elizinzile lika-Greater noma elilingana nama-95% (ngaphandle kwesondlo). Sihlinzeka ngamadokhumenti ekhwalithi ephelele, okuhlanganisa izitifiketi zezinto ezibonakalayo, imibiko yokusebenza kwe-cryogenic, nezitifiketi zokuphepha.
Isevisi ephumelelayo iqinisekisa ukukhiqizwa kwe-LNG okuqhubekayo nokuphephile. Lapho lithola isicelo sesevisi, ithimba lethu lobuchwepheshe linikeza impendulo yokuqala phakathi kwamahora angu-12 (24/7) ngefoni, i-imeyili, noma ividiyo. Ezindabeni ezikude (isb., ukwenziwa ngcono kwepharamitha), siqondisa ukulungiswa kungakapheli amahora angama-24; ngezidingo-zesayithi, onjiniyela bathunyelwa emahoreni angu-48 (zasekhaya) noma amahora angu-72 (amazwe ngamazwe). Siphinde sinikeze ngezinhlelo zokulungisa ezijwayelekile (okuhlanganisa ukuhlanzwa kwesishintshi sokushisa kanye nokugcwaliswa kabusha kwesiqandisi) ukuze kuncishiswe isikhathi sokuphumula.
Inkampani yethu ihlinzeka ngamaphrojekthi we-EPC turnkey wePlant Yegesi Yemvelo Encibilikisiwe eyenziwe ngokwezifiso, kanye nezinsizakalo zobuchwepheshe ezifana nokwenza ngcono inqubo nokuqeqeshwa komsebenzisi. Kumakhasimende adinga ukuhlinzekwa kwe-LNG, sinikeza amamodeli ebhizinisi elihlanganyelwe ({1}}ngokutshala imali ezitshalweni nokwabelana ngokukhiphayo) ukuze kwehliswe ingcindezi yokuqala yokutshala imali.
