Isityalo se-LNG Liquefaction esifakelwe kwi-micro skid esi-5 kunye nesityalo se-LNG sokucoca ulwelo
iinkcukacha zemveliso
Igesi yendalo enyibilikisiweyo (i-LNG) yigesi yendalo, ikakhulu i-methane, epholileyo yaya kwimo engamanzi ukuze kube lula ukugcina nokuthutha. Ithatha malunga ne-1/600th yomthamo wegesi yendalo kwimeko yegesi. Sibonelela ngeZityalo zokunyibilikisa igesi yendalo kwi-micro (mini) kunye ne-small scale. Umthamo wezityalo ugubungela ukusuka kwi-13 ukuya ngaphezulu kwe-200 Tons/ngosuku lwemveliso ye-LNG (18,000 ukuya kwi-300,000 Nm3/ngosuku). Igesi yokutya: ● Amasimi egesi aqinileyo ● Igesi edibeneyo / evuthayo ● I-Biogas ● Igesi yephayiphi Isityalo esipheleleyo sokunyibilikisa igesi se-LNG siquka iinkqubo ezintathu: inkqubo yenkqubo, inkqubo yolawulo lwezixhobo kunye nenkqubo yokusetyenziswa. Ngokwemithombo yomoya eyahlukeneyo, inokutshintshwa. Ngokwemeko yokwenyani yomthombo wegesi, samkela inkqubo engcono kunye nesicwangciso esinoqoqosho ukuhlangabezana neemfuno ezahlukeneyo zabathengi. Izixhobo ezifakwe kwi-skid zenza ukuthuthwa nokufakwa kube lula ngakumbi. 1. Inkqubo yenkqubo Igesi yendalo yokufunxa ifakwa uxinzelelo emva kokuhluzwa, ukwahlukana, ulawulo loxinzelelo kunye nokulinganisa, ize ingene kwinkqubo yokufunxa igesi yendalo. Emva kokususa i-CO2, i-H2S, i-Hg, i-H2O kunye nee-hydrocarbons ezinzima, ingena kwibhokisi ebandayo yokufunxa. Emva koko ipholiswa kwi-plate fin heat exchanger, i-denitrified emva kokufunxa, ize ipholiswe kancinci, itshiswe kwaye ikhanyelwe kwi-flash tank, kwaye okokugqibela, isigaba solwelo esahlulweyo singena kwi-LNG yokugcina njengeemveliso ze-LNG. Itshati yokuhamba kwesityalo se-LNG esifakwe kwi-skid yile ilandelayo: Inkqubo yesityalo se-cryogenic LNG ibandakanya: ● Ukuhluzwa kwegesi yokufunxa, ukwahlula, ulawulo loxinzelelo kunye neyunithi yokumitha; ● Iyunithi yokufunxa igesi yokufunxa ● Iyunithi yokufunxa (kubandakanya ukufunxa, ukuphelelwa ngamanzi kunye nokususwa kwe-hydrocarbon enzima, ukususwa kwe-mercury kunye nothuli); ● Iyunithi yokulinganisela ye-MR kunye neyunithi yomjikelo wokucinezela kwe-MR; ● Iyunithi yokufunxa i-LNG (kubandakanya iyunithi yokufunxa); 1.1 Iimpawu zenkqubo yenkqubo 1.1.1 Iyunithi yonyango lwangaphambi kwegesi yokutya Indlela yenkqubo yeyunithi yonyango lwangaphambi kwegesi yokutya ineempawu ezilandelayo: ● Ukususa i-asidi ngesisombululo se-MDEA kuneenzuzo zokufutha okuncinci, ukubola okuphantsi kunye nokulahleka okuncinci kwe-amine. ● Ukufuthwa kwesihluzo se-molecular kusetyenziselwa ukuphelelwa ngamanzi emzimbeni okunzulu, kwaye kusenenzuzo ephezulu yokufuthwa kwamanzi nokuba kuphantsi koxinzelelo oluncinci lomphunga wamanzi. ● Ukusebenzisa ikhabhoni esebenzayo efakwe i-sulfur ukususa i-mercury kubiza kancinci. I-Mercury isabela ne-sulfur kwikhabhoni esebenzayo efakwe i-sulfur ukuvelisa i-mercury sulfide, efuthwa kwikhabhoni esebenzayo ukufezekisa injongo yokususwa kwe-mercury. ● Izinto zokucoca ngokuchanekileyo zinokuhluza isihluzo se-molecular kunye nothuli lwekhabhoni olusebenzayo ngaphantsi kwe-5μm. 1.1.2 Iyunithi yolwelo kunye nefriji Indlela yenkqubo ekhethiweyo yeyunithi yolwelo kunye nefriji yi-MRC (mixed refrigerant) cycle refrigerant, esetyenziswa kancinci ngamandla. Le ndlela inokusetyenziswa kwamandla okuphantsi phakathi kweendlela zolwelo ezisetyenziswa rhoqo, okwenza ixabiso lemveliso likhuphisane kwimarike. Iyunithi yokulinganisa i-refrigerant ayixhomekekanga kwiyunithi yoxinzelelo olujikelezayo. Ngexesha lokusebenza, iyunithi yokulinganisa iphinda izalise i-refrigerant kwiyunithi yoxinzelelo olujikelezayo, igcina imeko yokusebenza ezinzileyo yeyunithi yoxinzelelo olujikelezayo; Emva kokuba iyunithi ivaliwe, iyunithi yokulinganisa inokugcina i-refrigerant kwinxalenye yoxinzelelo oluphezulu lweyunithi yoxinzelelo ngaphandle kokukhupha i-refrigerant. Oku akunakugcina kuphela i-refrigerant, kodwa kunciphise nexesha elilandelayo lokuqalisa. Zonke iivalvu ezikwibhokisi ebandayo zihlanganisiwe, kwaye akukho qhagamshelo lwe-flange kwibhokisi ebandayo ukunciphisa iindawo zokuvuza ezinokubakho kwibhokisi ebandayo. 1.2 Izixhobo eziphambili zeYunithi nganye S/N Igama leYunithi Izixhobo eziphambili 1 Ukwahlulahlula kunye nokulawula i-feed gas filtration Iyunithi yokwahlulahlula kunye nokulawula i-feed gas filter, i-flowmeter, i-pressure regulator, i-feed gas compressor 2 Iyunithi yonyango lwangaphambi konyango Iyunithi yokufunxa kunye ne-regenerator Iyunithi yokufunxa amanzi emzimbeni I-Adsorption tower, i-regeneration heater, i-regeneration gas cooler kunye ne-regeneration gas separator Iyunithi yokususa i-hydrocarbon eninzi I-Adsorption tower Iyunithi yokususa kunye nokucoca i-Mercury remover kunye ne-dust filter 3 Iyunithi yolwelo Ibhokisi ebandayo, i-plate heat exchanger, i-separator, i-denitrification tower 4 Iyunithi yokupholisa i-refrigerant exutyiweyo I-refrigerant circulating compressor kunye ne-refrigerant proportional tank 5 Iyunithi yokulayisha i-LNG Inkqubo yokulayisha 6 Iyunithi yokubuyisela i-Bog regenerator 2. Inkqubo yolawulo lwezixhobo Ukuze kujongwe ngokufanelekileyo inkqubo yemveliso yeseti epheleleyo yezixhobo, kunye nokuqinisekisa ukusebenza okuthembekileyo kunye nokusebenza kunye nokugcinwa okulula, inkqubo yolawulo lwezixhobo ibandakanya ikakhulu: Inkqubo yokulawula esasazwayo (DCS) Inkqubo yeZixhobo zoKhuseleko (SIS) Inkqubo ye-Fire Alarm kunye ne-Gas Detector (FGS) Ithelevishini yesekethe evaliweyo (CCTV) Inkqubo yohlalutyo kunye nezixhobo ezichanekileyo kakhulu (i-flowmeter, i-analyzer, i-thermometer, i-pressure gage) ezihlangabezana neemfuno zenkqubo. Le nkqubo ibonelela ngemisebenzi yoqwalaselo olugqibeleleyo, ukuqalisa kunye nokubeka esweni, kubandakanya ukufunyanwa kwedatha yenkqubo, ulawulo oluvaliweyo, imeko yokujonga ukusebenza kwezixhobo, ukunxibelelana kwe-alamu kunye nenkonzo, ukucubungula idatha ngexesha langempela kunye nokubonisa, inkonzo yefashoni, umboniso wemizobo, inkonzo yengxelo yerekhodi yokusebenza kunye neminye imisebenzi. Xa kukho imeko engxamisekileyo kwiyunithi yemveliso okanye inkqubo ye-FGS ithumela isignali ye-alamu, i-SIS ithumela isignali yokukhusela ukuvala ukukhusela izixhobo ezikwindawo, kwaye inkqubo ye-FGS yazisa isebe lomlilo lasekuhlaleni ngaxeshanye. 3. Inkqubo yokusetyenziswa Le nkqubo ibandakanya ikakhulu: iyunithi yomoya wesixhobo, iyunithi ye-nitrogen, iyunithi yeoyile yokudlulisa ubushushu, iyunithi yamanzi acocekileyo kunye neyunithi yamanzi ajikelezayo okupholisa. Ekupheleni kuka-2025, iHengzhong yayineeprojekthi ze-LNG ezingama-32. Ezi projekthi ziquka izityalo zeMini LNG, iMicro LNG, kunye ne-LNG ezinamazinga okuhamba aqala kwi-2 ukuya kwi-10 MMSCFD, kwaye abathengi yi-Iran, iRashiya, kunye neTshayina.
