Abstract
A system stores densely dissolved methane-base gas and supplies gas of a predetermined composition. A container (10) stores methane-base gas dissolved in hydrocarbon solvent and supplies it to means for adjusting composition, through which an object of regulated contents is obtained. Preferably, the means for adjusting composition is means for maintaining the tank in a supercritical state, or piping (48) for extracting substances at a predetermined ratio from the gas phase (12) and liquid phase (16) in the container.
