摘要

"Process to reduce the acidity and the calcium content of a crude oil acid of departure have not pre treated with acid containing calcium.The present invention describes a process to decrease the acidity of a crude oil acid treated with acid containing calcium of departure by the addition of a crude oil acid in a quantityEffective solution of aqueous base under conditions of pH and temperature sufficient to form an emulsion unstable in crude oil acid in the solution of aqueous base; and breaking the emulsion to form aPhase containing crude oil treated with acidity and residue of the aqueous phase decreased by containing base and acids are neutralized. The invention has utility in processing crude oil.
