It has become trend that high sulfa content raw oil occupies more and more shares in oil refinery. In this article, the corrosion mechanism of sulfa contented oil and affcets influeneing sulfa corrosion were introdueed. The refining methods for high sulfa content oil and protection measures for the corrosion were also described. Emphatically, the experiences from processing high sulfa content oil in atmospheric and vacuum plant in Maoming were introdueed. At the same limes, the antieurrosion measures and proposals for processing high sulfa content oil in refineries were presented.针对目前高硫等劣质原油在炼厂加工所占比例越来越大的趋势，介绍了原油中硫的分布规律及其危害性，含硫原油的腐蚀机理及影响硫腐蚀的各种因素、阐述近年来高硫原油的加工方法及防护措施，着重介绍了茂名分公司作为高硫原油加工基地常减压装置加工高硫原油的经验，并提出了炼厂加工高硫原油的防腐措施和建议。
