| 摘 要： | 中国石油化工股份有限公司武汉分公司通过实验室试验及分析检测,确定了催化裂化精制汽油铜片腐蚀试验通不过的原因是多硫化物。对多硫化物产生的原因进行研究表明,汽油铜片腐蚀不合格与精制过程中的纤维膜接触器无关,而与进入精制系统前汽油中所携带的单质硫有关。通过采取一系列措施有效地解决了汽油铜片腐蚀不合格的问题。

| Abstract: | Though laboratory test and analysis,the culprit for failure of treated FCC gasoline copper strip test is polysulfide.The research on presence of polysulfide shows that failure of the gasoline copper strip test has nothing to do with MERICAT treater and it relates to the element sulfur entrained in the gasoline before en- tering treating system.After taking effective measures,the gasoline successfully passes the copper strip corro- sion test. |
