Abstract (en)
The method involves cooling a liquefied petroleum gas bottle between minus 5-minus 10 degrees when the bottle contains butane and between minus 50-minus 55 degrees when the bottle contains propane. A faucet of the cooled bottle is removed. A sealing device comprising an inert gas injection orifice (9) is fitted to a neck (8) of the cooled bottle. Pressurized inert gas e.g. carbon dioxide or nitrogen, is injected by supplying the liquefied petroleum gas to the exterior. The sealing device is withdrawn from the bottle. An independent claim is also included for an installation for evacuation of a liquefied petroleum gas bottle.
