升高再生器中催化剂界面可改善ＦＣＣ效率和经济性炼油厂往往把ＦＣＣ装置再生器中的催化剂界面控制在尽可能低的水平以尽量减少催化剂藏量。这一界面的低限是旋风分离器料腿的底端，是通过再生器顶和底的压差来测量的。ＦＣＣ装置的一个重要参数是烧焦能力。较高的再生器...
Increasing the catalyst interface in the regenerator improves FCC efficiency and economy Refineries often keep the catalyst interface in the FCC unit regenerator as low as possible to minimize catalyst inventory. The lower limit of this screen is the bottom end of the cyclone leg, measured by the differential pressure between the top and bottom of the regenerator. An important parameter of the FCC unit is the scorch capacity. Higher regenerator ...
