摘要
针对目前炼油厂冷换设备各单项防腐技术存在的缺陷,进行了涂料-阴极保护、化学镀-阴极保护、缓蚀剂-涂料、缓蚀剂-化学镀、缓蚀剂-耐蚀金属材料、缓蚀剂-阴极保护、冷却水系统缓蚀剂之间共7项冷换设备防腐技术协同效应的实验室研究。结果表明,炼油厂冷换设备防腐技术协同应用后,无论是技术指标还是经济性,都可以获得几十、甚至上百倍的提高,协同效应产生的是“1+1>2”的效果。随后又进行了2项工业试验,同样获得了良好的技术和经济效果。
Analyzed in this paper are the drawbacks of every single anti-corrosion technology for the heat exchanger in refinery. The laboratory study of the synergistic effect of seven anti-corrosion technologies including coating-cathodic protection, chemical plating-cathodic protection, corrosion inhibitor-coating, corrosion inhibitor-chemical plating, corrosion inhibitor-corrosion resistant metal material, corrosion resistant-cathodic protection and inter-corrosion inhibitor are carried out. The study results indicate that after all the anti-corrosion technologies are applied synergistically, both the technical index and economical index are increased by tens or hundreds of times. The synergistic effect is the effect of 'one plus one is bigger than two'. Subsequently, two industrial tests are performed and the same good technical and economical effects are obtained.
