摘要
介绍了CS喷嘴在120×104t/a催化裂化装置的应用情况。工业试验结果表明,在原料油性质、催化剂性质和操作条件基本相同的情况下,使用CS喷嘴后,改善了产品分布,降低装置运行费用。干气收率降低了1.5个百分点;焦炭收率降低了1.2个百分点;液化气产率提高了1.3个百分点;汽油产率提高了1.1个百分点;柴油产率提高了0.3个百分点。CS喷嘴对产物性质无不良影响。年增加综合经济效益6 126万元。
The application of CS type feed nozzle in FCC unit was introduced. The industrial results showed that after the application of CS type feed nozzle, the product distributing was improved with the same raw material, catalyst, operation condition. The operation cost was decreased. The yields of gas and petroleum coke were reduced 1.5 % and 1.2%. The yields of LPG, gasoline and diesel oil were increased 1.3 %, 1.1% and 0.3% respeceively. The products were not affected by CS type feed nozzle. The integrated economy benefit was increased 61.26 million per year.
