Abstract

The present invention provides a method for the desalting of fuel oil by mixing the fuel oil and clean water, thereby separating and eliminating sodium salts and potassium salts contained in the fuel oil, and the method comprises separating a heavy portion including salt-containing water from the fuel oil which is a light portion, this heavy portion separated from the fuel oil being separated into water and a residue by an evaporator, the water being reused as a washing water and the residue being burnt to use the generated heat as a heat source for the evaporator, whereby the residue is decreased in volume and solidified to be made easy in the handling.
