ABSTRACT:
Manipulating a body of crude petroleum to remove foreign matter present therein by introducing crude oil and water into a container and then introduing a mass of material which is at cryothermal temperature to cause freezing of the water and an increase in the surface tension of the petroleum crude. The cryothermal temperature corresponds to the freezing temperature of water and to lower temperatures. The method also provides for heating of the petroleum and frozen water in the container prior to the removal of the treated oil. The method aids in the expulsion of foreign matter from crude petroleum.
