Abstract
The invention relates to processes for treating acidic crudes or fractions thereof to reduce or eliminate their acidity and corrosivity by addition of suitable amounts of Group IA or Group IIA oxides, hydroxides and hydrates and Group IIA metal naphthenate salts. 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.
