摘要:
重油催化裂化焦炭产率较高,会加重再生器负荷,降低剂油比和轻质油收率。对此,在催化裂化装置基础上添加外取热器。通过采用外取热和外甩油浆相结合的方法,实现重油催化裂化轻质油收率的提高。外取热器的作用是为了快速有效将再生器部分过多的热量取走,达到再生催化剂降温的目的。外甩油浆的作用是为了降低焦炭产率,减少烧焦产生热量。热量的降低可以有效提高剂油比,增加轻质油收率。原料残炭值的大小对产品分布有直接影响。原料残炭值越大,催化裂化装置的反应器部分产生焦炭越多,待生催化剂上含碳量也会升高,到达再生器烧焦以后释放大量的热量,热量增加不仅会影响再生器的寿命,也会使催化裂化装置中的剂油比降低,从而降低轻质油收率。通过控制向量参数化方法对CO助燃剂、主风、外取热和外甩油浆进行了不同层次的调控与优化,结果发现,对于重油催化裂化,CO助燃剂、主风的优化影响效果有限,而外取热和外甩油浆相互促进可以有效提高剂油比和轻质油收率。
