PROCESS FOR NEUTRALIZATION OF PETROLEUM ACIDS USING OVERBASED DETERGENTS

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 ~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.
