摘要： This disclosure relates to devices, e.g., baffle plate and combination dipleg valve/baffle devices, for use in achieving rapid disengagement of entrained hydrocarbons vapors, especially in high flux spent catalyst flow exiting from a cyclone separator dipleg in a fluidized catalytic cracking (FCC) unit. The baffle plate is preferably located near and typically below the catalyst dipleg of a fluid catalytic cracking reactor or separation zone and comprises a baffle plate body member having a surface, and in preferred embodiments also includes one or more apertures located on at least a portion of the surface. The valve/baffle is located at the outlet of the catalyst dipleg and comprises a combination valve and catalyst baffle in which the valve/baffle is designed to allow the top surface of the valve/baffle to seat against the dipleg outlet until the weight of the catalyst above the valve/baffle forces it to open. This disclosure also relates to FCC units that include the devices, and FCC methods utilizing the devices.
摘要翻译：本公开涉及用于实现夹带的烃蒸气的快速脱离，特别是在流化床催化裂化（FCC）中从旋风分离器三通流出来的高通量废催化剂流中的装置，例如挡板和组合式二通阀/挡板装置，单元。挡板优选地位于流化床催化裂化反应器或分离区的催化剂二段附近并且通常位于其下方，并且包括具有表面的挡板主体构件，并且在优选实施例中还包括位于至少一部分上的一个或多个孔表面。阀/挡板位于催化剂液滴的出口处，并且包括组合阀和催化剂挡板，其中阀/挡板被设计成允许阀/挡板的顶表面抵靠径向出口抵靠直到重量在阀/挡板上方的催化剂迫使其打开。本公开还涉及包括设备的FCC单元以及利用该设备的FCC方法。
