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。
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.
