PROCESS FOR DECREASING THE CORROSIVITY AND ACIDITY OF PETROLEUM CRUDES

摘要

The invention relates to a process for treating acidic crudes or fractions thereof to reduce or eliminate their corrosivity by addition of suitable amounts of Group IA or Group IIA oxides, hydroxides, hydroxides hydrates or naphthenate salts to an acidic, corrosive crude, or by reblending a naphthenate salt-containing crude in appropriate ratios with an acidic corrosive crude. The process has the additional benefits of reducing materials handling problems associated with treating acidic crude oils using liquid solvents and in reducing emulsion formation.
