摘要
中国石油辽河石化分公司采用石油大学(华东)开发、华东设计院设计的两段提升管催化裂化技术,对800kt／a催化裂化装置反应-再生、分馏、吸收稳定等部分进行改造。通过一系列的调整优化,诸如选用适宜的降烯烃催化剂,选择合适的汽油馏分进行回炼并优化回炼比,以及调整操作参数等措施,使改造后的装置较好地发挥了两段提升管技术的优势:汽油烯烃降低,辛烷值损失不大;目的产品收率略有上升,柴汽比得以改善。
The technology of two-stage riser fluid catalytic cracking developed by the University of Petroleum （East China） and designed by the East China Design Institute was applied in the 800 kt/a fluid catalytic cracking unit of Liaohe Petrochemical Company. The revamping of the unit included the reaction/regeneration system, the fractionation system and the absorption /stabilization System. A series of optimal adjustments was conducted, such as selecting suitable catalysts with olefin reduction function, varying the distillation range and amount of recycling naphtha, adjusting other related operation parameters and etc. This optimized process exhibited the flexibility and adaptability of the two-stage riser technology. The production results showed that the olefin content of the naphtha reduced with minimum octane loss; the light products yield and the ratio of LCO/naphtha improved.
