CS-Ⅱ型喷嘴在 MIP重油催化裂化装置的工业应用

摘要

介绍了 CS-Ⅱ喷嘴在1.7Mt/a 重油催化裂化装置的应用情况。工业试验结果表明，在原料、催化剂、操作条件不变的情况下，改善了产品分布。使用 CS-Ⅱ喷嘴后液化气收率提高了1.3个百分点；汽油收率提高了1.1个百分点；柴油收率提高了0.3个百分点。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；对产物性质无不良影响。证明 CS-Ⅱ喷嘴能有效地改善产品分布。%Application of CS-Ⅱ type feed nozzle in 1.7Mt/a RFCC unit was introduced. The application results show that, after application of CS-Ⅱ type feed nozzle, the product distribution can be improved with the same raw materials, catalyst, operation conditions; the yields of LPG, gasoline and diesel oil can be increased by 1.3%, 1.1% and 0.3%, respectively; the yields of gas and petroleum coke can be reduced 1.5% and 1.2%, respectively; the quality of products is not affected.
