【摘要】 通过对广州分公司蜡油催化裂化装置流化异常现象分析,从流化理论的基本概念着手,分析了产生流化 失常的原因,并提出了解决措施:调节再生催化剂筛分组成,保持催化剂中粒径在40μm以下的细粉含量在10％左 右,适当提高主风量,调整脱气罐的松动点和松动风量,增加待生线路推动力等。更多还原

【Abstract】 The abnormal fluidizing in VGO FCC unit of Guangzhou Company has been analyzed based on the basic concept of fluidization theory and the countenneasures have been proposed as follows: (1) Adjusting the size composition of regenerated catalyst to maintain the content of fines with particle size below 40 μm at about 10% ; (2) Properly increasing the main air quantity; (3) Adjusting aeration point and aeration air quantity of the degasser and enhancing the driving power of waste catalyst pipeline.更多还原
