摘要
原油中的氯对炼油生产装置带来危害,特别是由于有机氯在加工过程中分解,即使在原油电脱盐良好的情况下,仍然会在后续加工装置中引起比较严重的氯化物腐蚀、结盐等问题。介绍了目前常见的盐含量、总氯及有机氯含量的测量技术。
The chloridesin in crude oil are harmful to refinery units, especially, even if the inorganic chloride salts were removed well through the crude oil desalination, the corrosion of wet hydrogen chloride and deposition of chloride salts may appear because of hydrolysis and thermal degradation of the organic chlorides in refinery process. The methods generally used to detect the concentrations of salts, total chloride and organic chloride are introduced.
