Process of complete cryogenic vaporization of liquefied natural gas

摘要: Liquefied natural gas is cryogenically vaporized completely while being utilized as a cryogen for cryogenic heat-exchange process by vaporizing the liquefied first vaporization step at temperature lower than -110 DEG C until non-vaporized residue of becomes predetermined amount which in range between critical percentage higher hydrocarbons residual are frozen out therefrom and 8% percentage, separating from gas, conditioning to -40 then, second introducing it into conditioned gas.
