ABSTRACT:
The present invention describes a process for decreasing the acidity of a starting calcium containing, non-acid treated acidic crude oil by adding such an acidic crude oil to an effective amount of an aqueous base solution at conditions of pH and temperature sufficient to form an unstable emulsion of the acidic crude oil in the aqueous base solution; and breaking the emulsion to form a phase containing treated crude oil having a decreased acidity and aqueous phase residual containing base and neutralized acids. The invention has utility in crude oil processing.
