Abstract (en)

[origin: EP0198988A1] 1. A process for emptying containers (1) which have contained liquefied gas derived from petrol and/or the chemical or petrochemical industry, characterized in that it consist of admitting under pressure the gas to be removed (1b, 1c) from these containers into an exchanger (3) with a large exchange surface in counterflow to a liquefied inert gas (3a) introduced into this exchanger and injecting this inert gas, after it has yielded up its cooling power, into the said containers to re-introduce it, at the same time as the gas which is to be recovered, into the said exchanger, thus forming a circulation loop, then to recover at the oulet (3c) of the said exchanger a liquid phase of the gas desired, to be introduced, in its turn, into a storage container (5) or into the container of an appropriate transporter.
