【摘要】 近 10年来 ,随着进口原油的增多 ,石油化工设备的腐蚀重点逐步由环烷酸腐蚀转向硫化物腐蚀。腐蚀研究与防护的重点主要是合理选择抗腐蚀材料与加强表面防护 ,加强原油的电脱盐 /电脱水、注新鲜水 /加破乳剂、注缓蚀剂和注中和剂等。着重介绍了近年来国内研究开发及采用的腐蚀与防护技术和措施更多还原

【Abstract】 With the increase of petroleum importation, the corrosion protection emphases of petroleum chemistry facilities turned from naphthenic acid corrosion to sulfide corrosion in decade. The corrosion protection study emphases are: to facilities material, enhancing the reasonable choice of anticorrosion material and facial protection;enhancing the electrical desalting /dewatering of petroleum, adding the wash water/emulsion breaker, adding inhibitor and neutralizer etc. Research development and application of corrosion protection technique in China are introduced.更多还原
