| Abstract: | The equipment corrosion and corrosion resistance in processing crude oil with high acid value are reviewed.Research results in this field have been reported but there are still many questions that are not completely understood.Based on the analysis of corrosion mechanism of naphthenic acid,the major factors affecting the naphthenic acid corrosion,including crude oil composition,operation temperature,fluid velocity and flow pattern,pressure and metallurgy of equipment materials,are discussed. The corrosion prevention techniques during the refining of crude oil with high acid value are also introduced. |
