摘要:
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.

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.
摘要:
The invention relates to a process for treating naphthenic acid containing whole crudes or fraction thereof to reduce or eliminate their acidity by contacting the acidic whole crude or fractions thereof at a suitable temperature typically of less than 200.degree. C. with a neutralizing amount typically from 0.25:1 up to 10:1 of overbased detergent. The process has the additional benefits of reducing materials handling problems associated with emulsion formation in treated crudes.
摘要:
The present invention is a process to remove a +2 ionic charged, organically bound metal from a petroleum feed. The process includes contacting feed with aqueous carbon dioxide in the essential absence for emulsion formation.
