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