Tuam Tshoj LNG cog Skid Hoobkas - 10 ~ 20 × 104m3 / D kev cai LNG Liquefaction Cog - Rongteng

Nature of LNG

a) Kev sib xyaw

LNG / LCBM yog hydrocarbon sib tov nrog methane ua cov khoom tseem ceeb, uas muaj ib qho me me ntawm ethane, propane, nitrogen thiab lwm yam khoom siv feem ntau muaj nyob hauv cov nkev.

Feem ntau hais lus, cov ntsiab lus methane ntawm LNG / LCBM yog siab dua 80% thiab cov ntsiab lus nitrogen tsawg dua 3%.

Txawm hais tias lub ntsiab lus tseem ceeb ntawm LNG yog methane, lub cev thiab tshuaj lom neeg ntawm LNG tsis tuaj yeem xam los ntawm cov methane ntshiab.

Lub cev thiab thermodynamic zog ntawm methane thiab lwm yam khoom siv roj ntsha tuaj yeem pom nyob rau hauv cov ntaub ntawv siv tau thiab cov phau ntawv qhia txog kev ntsuas ntsuas kub.

b) Qhov ntom ntom

Qhov ceev ntawm LNG / LCBM nyob ntawm nws cov khoom, feem ntau ntawm 430kg / m3 thiab 470kg / m3, tab sis qee zaum nws tuaj yeem siab txog 520kg / m3. Qhov ceev kuj yog qhov ua haujlwm ntawm cov kua kub, thiab nws qhov kev hloov pauv yog li 1.35kg / m3. ℃.
