Abstract (en)

[origin: WO9904101A1] The invention relates to a method of recovering oil from water or soil, in which method the oil is cooled by a cryogenic cooling agent and is led into the collecting organs (1, 7, 10). The cooling is effected by leading the cooling agent onto the oil collection surface of the collecting organ (1, 7, 10), from which it has been set to absorb phase change heat of the oil into its own phase change and to be released outwards.
