| Abstract: | The trend of processing high acid value crudes and the equipment corrosion in processing operation are discussed. It is pointed that the crude compositions, operating temperature, fluid velocity and flow pattern, pressure and equipment metallurgy are the major factors affecting the naphthenic acid corrosion. The development and application of corrosion prevention technologies for the equipment in processing high acid value crudes are highlighted. The effective measures for mitigating the corrosion are appropriate crude oil blending, selection of corrosion-resistant materials such as 316L and aluminum-diffused steels and injection of corrosion inhibitors etc. |
