Liquefied natural gas ceev: {{0}}.42 ~ 0.46g/cm3. Qhov ceev ntawm gaseous natural gas yog li 1/625 ntawm liquefied natural gas, txog 0.000672 txog 0.000736 g/cm3.
Lub ntsiab tseem ceeb ntawm LNG yog methane, uas tau lees paub tias yog lub zog huv tshaj plaws hauv ntiaj teb. Tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom thiab tsis muaj corrosive, nws qhov ntim yog li 1/625 ntawm tib lub ntim ntawm cov pa roj carbon monoxide, thiab cov roj liquefied ntuj tsuas yog kwv yees li 45 feem pua ntawm tib lub ntim dej.
Cov pa roj carbon monoxide yog cov khoom siv sib xyaw ua ke ntawm cov roj av fossil, cov khoom tseem ceeb yog alkane, ntawm cov methane tso nyiaj rau feem coob, thiab muaj me me ntawm ethane, propane thiab butane. Nws tsuas yog muaj nyob rau hauv cov roj teb, gas teb, thee seams thiab shale formations.
Cov teb chaws thoob ntiaj teb kev tiv thaiv ib puag ncig tau txhawb nqa kev siv LNG. Ntxiv rau kev siv roj rau cov chaw tsim hluav taws xob, cov chaw tsim khoom, thiab cov neeg siv hauv tsev, cov methane muaj nyob rau hauv nws tuaj yeem siv los ua cov khoom siv tshuaj xws li chiv, methanol solvents, thiab hluavtaws acetic acid; Ethane thiab propane tuaj yeem tawg rau hauv ethylene thiab propylene, uas yog cov ntaub ntawv tseem ceeb rau cov khoom yas.
Ultra-tsawg kub LNG tuaj yeem muab ntau lub zog txias hauv cov txheej txheem ntawm kev hloov pauv mus rau qhov kub thiab txias hauv lub xeev nyob rau hauv atmospheric siab. Lub zog txias no tuaj yeem rov qab tau thiab siv tau rau hauv 6 qhov kev siv kub qis: kev sib cais ntawm huab cua los tsim cov pa oxygen, kua nitrogen, liquefaction Carbon dioxide, qhuav dej khov, siv lub zog txias rau lub zog tsim hluav taws xob, tsim cov khoom noj khov los yog siv rau hauv cov khoom khov. , low-temperature crushing treatment of industrial wastes xws li roj hmab, yas, hlau filings, seawater desalination.
