Abstract

In this article, the corrosion tests are studied for the high acidic crude oil, desalted crude oil, fractions of crude oil, atmospheric residual oil, crude oil of removing acid, viscosity-decreased residual oil, and fractions of viscosity-decreased residual oil. At the same time, the microanalysis of the test samples is performed, that is to say the surface configuration and surface componential of the test samples are observed and analyzed. Through the research of corrosion rules for the high-acidic crude oil, the selecting of equipment materials and the anti-corrosion scheme can be ensured while refining this kind of the high-acidic crude oil.
