Impumelelo ebalulekileyo ifezekisiwe kwi "Gulfstream LNG" yanamhlanjeIsityalo sokunyibilikisa ulwelo se-LNGngokuqaliswa ngempumelelo kwezixhobo zayo eziphambili zokucoca igesi yendalo. Eli nqanaba libalulekileyo liqinisekisa ukuba igesi yendalo engenayo ihlangabezana nemigangatho engqongqo yobumsulwa efunekayo ukuze kubekho ulwelo olusebenzayo nolukhuselekileyo, nto leyo evula indlela yokuqala ukusebenza ngokupheleleyo kwesi sityalo okucwangciselwe kamva kule kota.
Inkqubo edibeneyo yangaphambi konyango iqala ngoiyunithi yokususa igesi ene-asidi, inkqubo ebalulekileyo esebenzisa izinyibilikisi ezisekelwe kwi-amine eziphambili ukucoca igesi yendalo eluhlaza, isusa ngempumelelo izinto ezingcolisayo ezifana ne-hydrogen sulfide (H₂S) kunye ne-carbon dioxide (CO₂). Eli nyathelo libalulekile ukuthintela ukubola kwepayipi kunye nokuqinisekisa ukuba imveliso yokugqibela ye-LNG iyahlangabezana neemfuno zokusingqongileyo nezemarike.
Emva koko, umsinga wegesi uyaqhubeka uye kwiiyunithi yokuphelisa amanzi emzimbeni, esebenzisa ubuchwepheshe besihluzo semolekyuli ukukhupha wonke umphunga wamanzi. Ukususwa kwamanzi kubalulekile ukuthintela ukwakheka kwe-ice hydrates ngexesha lenkqubo ye-cryogenic, apho igesi ipholiswa ukuya kuthi ga kwi--162°C (-260°F) ukuze ibe lulwelo, ngaloo ndlela kuthintelwe ukuvaleka okunokwenzeka kunye nomonakalo kwizixhobo ezintsonkothileyo zokutshintshiselana ubushushu kunye neeturbines zesityalo.
Kwinyathelo elibalulekileyo elongeza ixabiso, esi sakhiwo sikwanazo ne-Ukufunyanwa kwe-NGL kwigesi yendaloinkqubo. Le yunithi isebenzisa iteknoloji ye-cryogenic turbo-expander ukwahlula nokubuyisela ii-Natural Gas Liquids (NGLs) ezixabisekileyo ezifana ne-ethane, i-propane, kunye ne-butane kumjelo we-methane. Ezi NGL emva koko ziyahlulwahlulwa kwaye zithengiswe njengeemveliso ezahlukeneyo, ezinexabiso eliphezulu, nto leyo ephucula ukusebenza kakuhle kweprojekthi ngelixa iqinisekisa ukuba i-methane eseleyo ilungiselelwe ngokufanelekileyo ulwelo.
“Ukuqaliswa okungenasiphako kwezi yunithi zangaphambi konyango bubungqina bobuchule bethu bobunjineli kunye nokusebenza kakuhle,” utshilo uMlawuli weProjekthi yesityalo, uNksz Anya Sharma. “Ngokuqinisekisa ukuba igesi yokufunxa ecocekileyo iphezulu, siphucula ukusebenza kakuhle kunye nokuthembeka koololiwe bethu bokunyibilikisa ulwelo, sibeka iGulfstream LNG njengomthengisi othembekileyo kwimarike yamandla yehlabathi.”
Ukuqaliswa ngempumelelo kwezi yunithi kubonisa impumelelo ebalulekileyo kwiprojekthi ebiza iibhiliyoni zeerandi, ekulungele ukuba negalelo elikhulu ekuthunyelweni kwe-LNG eMntla Melika, ibonelela ngomthombo wamandla othembekileyo nococekileyo kumaqabane aphesheya.
