Naphthenic acids (NAs) corrosion is a major problem to the oil refinery equipment in the petroleum industry when processed at high temperature of 220-340oC. The acidity level in the crude oil is measured by the Total Acid Number (TAN) value. In this study, a catalytic extraction method was introduce...
