Umgangatho oPhakamileyo waseTshayina aBaboneleli beZityalo zeGesi eziNcinane ze-LNG-Eyenziwe ngokwezifiso 2~10×104m3 / D umzi-mveliso wokunyibilikisa igesi yendalo – Iinkcukacha zaseRongteng:

Intshayelelo

Ukwakhiwa kweprojekthi 50 × 10⁴m³/ D iprojekthi yokunyibilikisa igesi yendalo kunye nezibonelelo ezixhasayo kunye ne-10000 m3 LNG enye itanki yomthamo ogcweleyo. Iiyunithi eziphambili zenkqubo ziquka i-feed gas pressurization, i-unit decarbonization, i-dehydration unit, i-mercury kunye neyunithi yokususwa kwe-hydrocarbon enzima, i-liquefaction unit, i-refrigerant storage, i-flash steam pressurization, ifama ye-LNG yetanki kunye nezixhobo zokulayisha.

Lusebenza njani unyango lokunyibilikiswa kwerhasi yendalo kwangaphambili?

Umjelo wequla lokutya kwezityalo ufika ngendlela enegesi ngombhobho. Igesi yendalo ekhutshwe emhlabeni iqulethe ukungcola, amanzi kunye nolunye ulwelo oluhambelanayo, ngoko ngaphambi kokuba i-liquefaction yenzeke, igesi kufuneka ihambe kwinkqubo yonyango ukususa izinto ezingafunekiyo. Irhasi idlula kuthotho lweenqanawa, iicompressors kunye nemibhobho apho irhasi yahlulwe ngokuthe ngcembe kulwelo olunzima kunye nokungcola.

Okokuqala, amanzi kunye ne-condensate ziyasuswa, zilandelweukususwa kwegesi ye-asidi(i-carbon dioxide, CO2), i-hydrogen sulfide (H2S) kunye ne-mercury (Hg). Ezi zinto azifunwa, njengoko zinokubangela ukuvela komkhenkce ngexesha lokunyibilika kunye nokuhlwa kwimibhobho kunye nokutshintsha ubushushu be-LNG. Umxube oseleyo ugqitywe ngaphambili, kunye nezinye, ezinzima, ulwelo lwegesi yendalo ke luhlulwe kumxube ngaphambi kokuba ulwelo lwenzeka. Iihydrocarbons ezisusiweyo zinokugcinwa kwaye zithengiswe ngokwahlukeneyo. Irhasi eshiyekileyo ubukhulu becala iqulathe imethane kunye ne-ethane ethile, ethi yenziwe ukunyibilikiswa.

I-Liquefaction ye-LNG isebenza njani?

Ukuthutha igesi ecinezelweyo imigama emide ngombhobho kunokuba yindleko kwaye idle ixesha, kodwa ngokupholisa igesi yendalo ukuya kwi-162 ° C, ijika ibe yinto engamanzi, kwaye umthamo wayo uyancipha ngamaxesha angama-600. Oku kwenza kube nokwenzeka ukuthutha igesi ngenqanawa, kwaye le nkqubo yenziwa yenzeka kwiplanti yeLNG. I-liquefaction kunye nenkqubo yokupholisa i-LNG isekelwe kwimijikelezo yefriji ye-thermodynamic, kwaye yenzeke kwi-cryogenic heat exchangers, ethatha ubushushu obuvela kwigesi yendalo. Irhasi yeflash kunye neBOG ingasetyenziswa njengamafutha kwiiiturbines ezisetyenziselwa ukwenziwa kombane kwisiza.

Sikakhulu sahlula phakathi kweentlobo ezimbini eziphambili zeenkqubo zokunyibilikisa: inkqubo ye-classical cascade apho iifriji ezahlukeneyo ezifunxayo kumaqondo obushushu ahlukeneyo zisetyenziswa, kunye nomjikelo wefriji oxutyiweyo apho umxube oqhubekayo, omnye weefriji apholiswa. Ngayiphi na indlela, imveliso yokugqibela yi-LNG, egcinwe kwiitanki ze-cryogenic kwisayithi ngaphambi kokuba ihanjiswe.

IsiKhokelo seMveliso esiNxulumeneyo:

Ngoku sineqela lethu lokuthengisa, iqela loyilo, iqela lobugcisa, abasebenzi be-QC kunye neqela lephakheji. Ngoku sineenkqubo ezingqongqo zolawulo lomgangatho ophezulu wenkqubo nganye. Kwakhona, bonke abasebenzi bethu banamava ekushicileleni uqeqesho loMgangatho oPhezulu waseChina ababoneleli beSityalo segesi esiNcinci se-LNG - elungiselelwe i-2 ~ 10 × 104m3 / D isityalo sokunyibilikisa igesi yendalo - iRongteng, Imveliso iya kubonelela kwihlabathi liphela, njenge: Mexico, Algeria, French, Siseke ixesha elide, elizinzileyo kunye nobudlelwane obuhle kunye nobudlelwane beshishini kunye nabathengisi abaninzi kwihlabathi liphela. Okwangoku, sijonge phambili kwintsebenziswano enkulu ngakumbi nabathengi baphesheya kweelwandle ngokusekwe kwizibonelelo ezifanayo. Kufuneka uzive ukhululekile ukuqhagamshelana nathi ngeenkcukacha ezithe kratya.
