Title: Underground butane store
Inventor: BOULANGER ALAIN
IPC: F25J1/02
Filed: 1983-09-02
Abstract: The method of storing butane underground in a cavern with a non-coated wall is characterised in that the temperature of the store is maintained at a value of -15 DEG C, substantially lower than that of the temperature of liquefaction of butane and lower than that of the freezing temperature of the ground. Furthermore, a gas which is inert with respect to butane is introduced into the gaseous atmosphere of the store in order to obtain a total pressure at least equal to atmospheric pressure. The ground is thus completely frozen and therefore impermeable around the cavern 1. Advantageously, propane from an adjacent propane store is used as the inert gas, the propane furthermore being used for cooling the butane.
