我厂加口工的鲁宁管输原油,盐和硫的含量均较高。为减缓炼制中漫备的腐蚀,除进行原油电脱盐以外,还在常压塔顶挥发线内注氨、缓蚀剂、急冷水。其中所用的缓蚀剂不沦“4502”,还是“7019”,都是水溶性的,对于低温轻油部位的初凝区,塔内构件,难以发挥保护作用,腐蚀仍比较严重。如果能找到一种既可中和酸性介质形成保护 I plant plus labor Lu Ning Pipeline crude oil, salt and sulfur content are higher. In order to slow down the pervasive corrosion in refining, in addition to the desalination of crude oil, ammonia is also injected into the volatilization line of the atmospheric tower, corrosion inhibitor and quench water. The corrosion inhibitors used therein are not reduced to “4502” or “7019”, and are water-soluble. For the initial condensing zone of low-temperature gas oil, the internals in the tower are difficult to exert protective effect and the corrosion is still serious. If you can find a neutralization of acidic medium can form a protection
