摘　　要：乌鲁木齐石化公司150万t/a重油催化裂化装置的第一、第二再生器的混合后再生烟气中仍然含有体积分数约为2%的CO,对环境造成污染及危害,也增加了装置能耗。通过强化第一再生器烧焦炭能力及改造第二再生器设备结构和烧焦炭方式,使第一、第二再生器催化剂均实现富氧完全再生,现有烟气中的CO完全燃烧,解决了上述问题。首先简要介绍了再生器改造的原因及思路,而后较为详细地论述了再生器改造内容、改造流程、施工的重点项、改造的效果等。实践表明,改造后中压蒸汽增加产量12.5 t/h,折合装置能耗,相当于降低原料能耗4.9 kgoe/t。The mixed flue gas from the first regenerator and the second regenerator of the 1 500 000 t/a heavy oil catalytic cracking unit in Urumqi Petrochemical Company still contains 2% CO, which is harmful to environment and increases en ergy consumption.The problem is solved by this method： enhancing coking ability of the first regenerator and reforming the structure and coking method of the second regenerator,enabling the catalytic agent in both regenerators to realize oxygen enrichment regeneration and CO complete burning. The reformation thoughts,contents,process flow,main construction items and reformation effect are illustrated. The reformation effect shows that the medium-pressure steam increases 12.5 t/h after the reformation,that equals to save the energy consumption of 4.9 kgoe/t.
