Isitshalo se-LNG Liquefaction esifakwe ku-micro skid esingu-6 MMSCFD kanye ne-Clean Energy

Igesi yemvelo encibilikisiwe (i-LNG) yigesi yemvelo, ikakhulukazi i-methane, epholile yaba uketshezi ukuze kube lula futhi kuphephe ukugcinwa nokuthuthwa. Ithatha cishe u-1/600th wevolumu yegesi yemvelo esimweni segesi. Sihlinzeka ngezitshalo zegesi yemvelo ezincibilikisiwe ngesilinganiso esincane (esincane) nesincane. Umthamo wezitshalo uhlanganisa kusukela ku-13 kuya ku-200 Tons/ngosuku lokukhiqizwa kwe-LNG (18,000 kuya ku-300,000 Nm3/ngosuku). Igesi yokudla: ● Amasimu egesi aqinile ● Igesi ehlobene / evuthayo ● Igesi ye-biogas ● Igesi yephayiphi Isitshalo esiphelele se-LNG liquefaction sihlanganisa izinhlelo ezintathu: uhlelo lwenqubo, uhlelo lokulawula izinsimbi kanye nohlelo lokusetshenziswa. Ngokusho kwemithombo yomoya ehlukene, singashintshwa. Ngokusho kwesimo sangempela somthombo wegesi, sisebenzisa inqubo engcono kakhulu kanye nohlelo olungabizi kakhulu ukuhlangabezana nezidingo ezahlukene zamakhasimende. Imishini efakwe ezikhiqizweni yenza ukuthuthwa nokufakwa kube lula kakhulu. 1. Uhlelo lwenqubo Igesi yemvelo ephakelwayo icindezelwa ngemva kokuhlunga, ukuhlukaniswa, ukulawulwa kwengcindezi kanye nokulinganisa, bese ingena ohlelweni lwegesi yemvelo ngaphambi kokwelashwa. Ngemva kokususa i-CO2, i-H2S, i-Hg, i-H2O kanye nama-hydrocarbon asindayo, ingena ebhokisini elibandayo le-liquefaction. Bese ipholiswa ku-plate fin heat exchanger, i-denitrified ngemva kokuxuba, bese ipholiswa ngaphansi, i-throttle bese ikhanya ethangini le-flash, bese ekugcineni, isigaba soketshezi esihlukanisiwe singena ethangini lokugcina i-LNG njengemikhiqizo ye-LNG. Ishadi lokugeleza kwesitshalo se-LNG esifakwe ku-skid linje: Uhlelo lwenqubo lwesitshalo se-LNG esicryogenic luhlanganisa: ● Ukuhlunga igesi ephakelwayo, ukuhlukaniswa, ukulawulwa kwengcindezi kanye neyunithi yokulinganisa; ● Iyunithi yokucindezela igesi ephakelwayo ● Iyunithi yokwelapha ngaphambi kokwelashwa (kufaka phakathi ukuqeda i-acid, ukuphelelwa amanzi emzimbeni kanye nokususwa kwe-hydrocarbon esindayo, ukususwa kwe-mercury nothuli); ● Iyunithi yokulinganisa i-MR kanye neyunithi yomjikelezo wokucindezela i-MR; ● Iyunithi yokuxuba i-LNG (kufaka phakathi iyunithi yokususa i-nitrification); 1.1 Izici zesistimu yenqubo 1.1.1 Iyunithi yokwelapha igesi yokuphakelayo Indlela yenqubo yeyunithi yokwelapha igesi yokuphakelayo inezici ezilandelayo: ● Ukuqeda i-acid ngesisombululo se-MDEA kunezinzuzo zokukhipha igwebu elincane, ukubola okuphansi kanye nokulahlekelwa okuncane kwe-amine. ● Ukumuncwa kwesihlungo sama-molecular kusetshenziselwa ukuphelelwa amanzi emzimbeni okujulile, futhi kusenenzuzo ephezulu yokumuncwa ngisho nangaphansi komfutho ophansi womhwamuko wamanzi. ● Ukusebenzisa ikhabhoni esebenzayo efakwe i-sulfur ukususa i-mercury kushibhile ngentengo. I-Mercury isabela ne-sulfur kukhabhoni esebenzayo efakwe i-sulfur ukuze ikhiqize i-mercury sulfide, efakwe kukhabhoni esebenzayo ukuze kufezwe injongo yokususwa kwe-mercury. ● Izinto zokuhlunga eziqondile zingahlunga isihlungo sama-molecule kanye nothuli lwekhabhoni olusebenzayo ngaphansi kwama-5μm. 1.1.2 Iyunithi yoketshezi kanye nefriji Indlela yenqubo ekhethiwe yeyunithi yoketshezi kanye nefriji yi-MRC (mixed refrigerant) cycle refrigerant, okuwukusetshenziswa kwamandla okuphansi. Le ndlela inokusetshenziswa kwamandla okuphansi kakhulu phakathi kwezindlela zokupholisa ezisetshenziswa kakhulu, okwenza intengo yomkhiqizo incintisane emakethe. Iyunithi yokulinganisa i-refrigerant ayizimele kakhulu kuyunithi yokucindezela ejikelezayo. Ngesikhathi sokusebenza, iyunithi yokulinganisa igcwalisa i-refrigerant kuyunithi yokucindezela ejikelezayo, igcina isimo sokusebenza esizinzile seyunithi yokucindezela ejikelezayo; Ngemva kokuba iyunithi ivaliwe, iyunithi yokulinganisa ingagcina i-refrigerant engxenyeni yokucindezela okuphezulu kweyunithi yokucindezela ngaphandle kokukhipha i-refrigerant. Lokhu ngeke nje konge i-refrigerant, kodwa futhi kufinyeze isikhathi sokuqala esilandelayo. Wonke ama-valve ebhokisini elibandayo ahlanganisiwe, futhi akukho ukuxhumana kwe-flange ebhokisini elibandayo ukunciphisa amaphuzu okuvuza okungenzeka ebhokisini elibandayo. 1.2 Imishini eyinhloko yeyunithi ngayinye S/N Igama leyunithi Imishini eyinhloko 1 Iyunithi yokuhlunga igesi yokuphakelayo kanye neyokulawula I-feed gas separator, i-flowmeter, i-pressure regulator, i-feed gas compressor 2 Iyunithi yokwelapha i-Deacidification Iyunithi ye-Absorber kanye ne-regenerator Iyunithi yokuhlanza amanzi I-Adsorption tower, i-regeneration heater, i-regeneration gas cooler kanye ne-regeneration gas separator Iyunithi yokususa ama-hydrocarbon amaningi I-Adsorption tower Iyunithi yokususa nokuhlunga i-Mercury remover kanye ne-dust filter 3 Iyunithi yokukhipha amanzi Ibhokisi elibandayo, i-plate heat exchanger, i-separator, i-denitrification tower 4 Iyunithi yokupholisa i-refrigerant exubile I-refrigerant circulating compressor kanye ne-refrigerant proportioning tank 5 Iyunithi yokulayisha i-LNG Uhlelo lokulayisha 6 Iyunithi yokubuyisa i-Bog regenerator 2. Uhlelo lokulawula izinsimbi Ukuze kuqashwe ngempumelelo inqubo yokukhiqiza yesethi ephelele yemishini, futhi kuqinisekiswe ukusebenza okuthembekile kanye nokusebenza okulula kanye nokugcinwa, uhlelo lokulawula izinsimbi luhlanganisa ikakhulukazi: Uhlelo lokulawula olusabalalisiwe (DCS) Uhlelo lwe-Safety Instrument (SIS) Uhlelo lwe-Fire Alarm kanye ne-Gas Detector (FGS) Ithelevishini ye-Closed-circuit (CCTV) Uhlelo lokuhlaziya kanye nezinsimbi ezinembe kakhulu (i-flowmeter, i-analyzer, i-thermometer, i-pressure gage) ehlangabezana nezidingo zenqubo. Lolu hlelo luhlinzeka ngemisebenzi ephelele yokucushwa, ukuqalwa kanye nokuqapha, okuhlanganisa ukutholwa kwedatha yenqubo, ukulawula okuvaliwe, isimo sokuqapha ukusebenza kwemishini, ukuxhumeka kwe-alamu kanye nesevisi, ukucubungula idatha yesikhathi sangempela kanye nokubonisa, isevisi yezitayela, ukubonisa imidwebo, isevisi yombiko werekhodi lokusebenza kanye neminye imisebenzi. Uma kukhona isimo esiphuthumayo kuyunithi yokukhiqiza noma uhlelo lwe-FGS luthumela isignali ye-alamu, i-SIS ithumela isignali yokuvikela ukuvala ukuze ivikele imishini esesayithini, kanti uhlelo lwe-FGS lwazisa umnyango wabacimi bomlilo bendawo ngesikhathi esifanayo. 3. Uhlelo lwezinsiza Lolu hlelo luhlanganisa kakhulu: iyunithi yomoya wezinsimbi, iyunithi ye-nitrogen, iyunithi kawoyela wokudlulisa ukushisa, iyunithi yamanzi akhishwe usawoti kanye neyunithi yamanzi ajikelezayo okupholisa. Ekupheleni kuka-2025, i-Hengzhong yayinamaphrojekthi angu-32 e-LNG. Lawa maphrojekthi afaka phakathi izitshalo ze-Mini LNG, i-Micro LNG, kanye ne-LNG ezinamazinga okugeleza asukela ku-2 kuya ku-10 MMSCFD, kanti amakhasimende yi-Iran, iRussia, kanye ne-China.
