LNG volume @ STP

[thorangle]

A cubic foot (or M^3) of Liquified Natural Gas. What is its expanded volume at standard temperature and pressure?

Thanks

Roughly 1 m3 of liquid gives 800 m3 gas.

thor - if you wonder how 800 came to be then consider the following:

Density of liquid methane == 600 kg/m3
Molecular weight of methane ==18 kg/kmol
1 Sm3 (15 deg C/1 atm)==0.042 mol

=> 1 m3 liq methane = 600/18/0.042 ==800 Sm3

Standar m3 is actually just another measure of moles
