Advanced ib puag ncig lub teb chaws thoob ntiaj teb tau txhawb nqa kev siv LNG. Dhau li ntawm nws siv roj hauv cov chaw tsim hluav taws xob, chaw tsim khoom, thiab tsev neeg, methane nws muaj tuaj yeem siv los tsim cov chiv, methanol cov kuab tshuaj, thiab ua cov khoom siv raw rau kev sib xyaw acetic acid thiab lwm yam tshuaj. Tsis tas li ntawd, ethane thiab propane nws muaj tuaj yeem tawg los tsim ethylene thiab propylene, cov ntaub ntawv tseem ceeb rau cov khoom siv yas.
Tsis tas li ntawd, cov txheej txheem ntawm cryogenically rhuab LNG hloov mus rau hauv chav tsev -kub gaseous xeev nyob rau hauv atmospheric siab muab ib tug tseem ceeb npaum li cas ntawm lub zog txias. Lub zog txias no tuaj yeem rov qab tau thiab siv rau hauv 6 daim ntawv thov cryogenic: sib cais huab cua los tsim cov pa oxygen thiab kua nitrogen, liquefying carbon dioxide, tsim cov dej khov qhuav, tsim hluav taws xob siv lub zog txias, tsim cov khoom noj khov los yog siv rau hauv qhov txias txias, cryogenic crushing ntawm industrial pov tseg xws li roj hmab, yas, thiab hlau filings, thiab seawater desalination.
Tau ntsib nrog kev ua qias tuaj ib puag ncig hnyav zuj zus, txhawm rau txhawm rau txhim kho kev siv hluav taws xob zoo, txhim kho huab cua ib puag ncig, thiab ua tiav lub tswv yim txhim kho kev lag luam, tib neeg tau xaiv cov roj av ua kom huv, ua tau zoo, thiab eco-tus phooj ywg siab- zoo zog thiab roj. Ob qho tib si kev lag luam thiab kev siv nyob hauv tsev tau dhau los ua kev vam khom rau cov roj ntsha. Liquefied natural gas (LNG) yog cov kua dej ntawm cov nkev ntuj. Hauv qee qhov xwm txheej, xaiv LNG muaj qhov zoo dua li xaiv cov pa roj carbon monoxide. Daim ntawv thov ntawm LNG yog qhov tseem ceeb ntawm daim ntawv thov ntawm cov pa roj, tab sis vim nws cov yam ntxwv, LNG muaj ntau yam kev siv ntau dua li cov nkev.
