A Study on the Deacidification of High-Acidity Crude Oil by Combined Solvents

摘要

Deacidification of high-acidity crude oil using a combined solvent was investigated by an orthogonal experiment (L_(16)(4)~5). Results indicate that the combined solvent has good deacidification performance to high-acidity crude oil. The combined solvent can be recovered and reused. In addition, the solvent can remove most of the naphthenic acid of crude oil, and the deacidification of crude oil can be reduced significantly.
