A process is disclosed for the removal of metals contaminants, particularly calcium, from hydrocarbonaceous feedstocks. The process comprises mixing the feedstock with an aqueous solution of a metals sequestering agent, particularly amino-carboxylic acids, their salts, or mixtures thereof, more particularly EDTA, and separating the aqueous solution containing the metals from the demetalated feedstock.
