Abstract

Method for transporting gas, in particular methane or natural gas, in a liquefied state, comprising the following operations: a) at a point of production, the gas is liquefied by cooling, and is introduced in a liquefied state in a tank; b) the tank thus filled is transported to a point of consumption; c) at the point of consumption, liquefied gas is regasified, placing it in heat exchange with a cold vehicle; d) the cold vehicle, cooled as a result of the operation described in c), is introduced into a tank; e) the tank, filled with cooled chilled vehicle, as described in d), is transported to the production point; f) at the point of production, the gas is cooled according to step a), placing it in heat exchange with the cold vehicle, supplied according to step e); the cold vehicle used being characterized, by a liquid vehicle which does not solidify during the heat exchange process, and which has a boiling point greater than, equal to, or just lower than the ambient temperature, and which contains particles of a substance that undergoes a phase change during the heat exchange process.
