    Abstract: 1,054,149. Liquefaction and re-vaporization of natural gas. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Nov. 8, 1965 [Nov. 9, 1964], No. 47244/65. Heading F4P. Liquefaction of natural hydrocarbon gas or revaporization of the gas in the liquid phase is effected by heat exchange with a refrigerant having a freezing point at atmospheric pressure near the boiling point of methane and having a boiling point above or slightly below ambient temperature. Suitable refrigerants include isobutane, isopentane, isohexane and mixtures thereof. After revaporization of liquid methane transported by tanker, the so-cooled refrigerant is fed into the tanker reservoir, transported back to the supply port and used to liquefy natural gas being loaded into the tanker. The so warmed refrigerant may be used as fuel or transported back to the unloading port.
