摘要
对催化裂化装置干气再吸收塔气体带液的问题进行了分析,认为在以密度较高的催化裂化柴油为吸收剂时,再吸收塔内形成了相对较严重的发泡体系。数套工业运行装置采用顶循环油代替柴油作为吸收剂后,不仅消除了干气携带柴油的问题,而且吸收效果得到明显改善,建议推广以顶循环油代替轻柴油作为干气再吸收塔吸收介质的技术改造。
The problem of LCO absorbent entrainment of dry gas reabsorber in FCCU is analyzed. It is thought that relative serious foam system formed in the reabsorber is the reason for the entrainment when the high density FCC LCO is used as an absorbent. After the replacement of FCC LCO absorbent with top cycle oil, the liquid entrainment of dry gas is eliminated and the absorption efficiency is improved greatly. It is suggested to use top cycle oil as absorbent for FCC dry gas reabsorber to eliminate entrainment and improve absorption efficiency.
