ABSTRACT:
A process for removing water from heavy crude oil uses an inorganic salt which is a Group IA or Group IIA metal halide or nitrate salts. The crude oil is in the form of a water-in-oil emulsion with water content of 8% (by weight) or less. The salt is stirred into the crude oil. The resulting mixture is warmed. A water layer with added salts and an oil layer form. The salts are water soluble and settle out of the crude oil layer with the water.
