PROGRESS ON INHIBITORS AND ASSESS METHOD FOR HIGH TEMPERATURE NAPHTHENIC ACID CORROSION
高温环烷酸腐蚀抑制剂及评定方法的研究进展

According to patents and literatures world wide,the inhibitors for high temperature naphthenic acid corrosion were classified into three types based on their constitute.Then the effective product of each type inhibitor was emphatically introduced.Among three types of inhibitors,the effectiveness of phosphor series is better than non-phosphor ones,however the compound type is the best in the present.For the assessment,the method of autoclave with metal coupon was usually used to assess the effectiveness of inhibitors.But it is necessary to established methods which may be fast,and also able to reproduce the practical technics conditions.
