Abstract

Crude petroleum oil is treated so as to reduce its sludge-forming tendency by heating from a temperature below 100 DEG F. and preferably not higher than 70 DEG F., to an elevated temperature, by dissolving in the oil compressed vapours which have been produced by auto-refrigeration of the oil. The elevated temperature is determined by experiment, and may be for example 140-150 DEG F. If the crude oil is at a temperature higher than 70 DEG F., it may first be cooled by auto-refrigeration, heated to the elevated temperature, and then cooled by auto-refrigeration, the vapours produced by the auto-refrigeration steps being compressed and dissolved in the oil after the first cooling step to provide some or all of the heat necessary for heating the oil. Specification 768,654 is referred to.
