Abstract: A baffle is installed on the wall of a regenerator vessel to push catalyst away from the wall to ensure adequate exposure to regeneration gas and complete combustion of coke from the catalyst. We have found that in deep beds, catalyst can flow down the walls and escape sufficient exposure to regeneration gas and undergo too little regeneration.

Abstract: Methods and apparatuses for regenerating catalysts and methods of inhibiting corrosion in catalyst regenerating apparatuses are provided. An exemplary apparatus includes: a metal vessel configured to receive a spent catalyst stream and contact at least a portion of the spent catalyst stream with an oxygen containing environment at a sufficiently high temperature to burn coke present in the spent catalyst stream; a refractory material overlying at least a portion of an inner surface of the metal vessel; and a corrosion inhibiting material in contact with at least a portion of the inner surface of the metal vessel and disposed between the inner surface and at least a portion of the refractory material, wherein the corrosion inhibiting material is heat stable at a temperature of at least up to about 400° F. (about 204° C.) and inhibits contact of an acid environment with the inner surface of the metal vessel.

Abstract: A regenerator for an FCC apparatus. The regenerator includes a riser inside of a shell. The riser includes a cone and a cone skirt. An annulus is formed between the riser and the shell. A sealing system for keeping catalyst out of a portion of the annulus comprises a first sealing element and a second sealing element disposed above the second sealing element. The second sealing element comprises a ring having one or more plates being movable to accommodate the thermal expansion of the riser.
Abstract translation: FCC设备的再生器。 再生器包括壳内的提升管。 提升器包括锥体和锥形裙部。 在提升管和壳体之间形成一个环。 用于将催化剂保持在环形空间的一部分之外的密封系统包括设置在第二密封元件上方的第一密封元件和第二密封元件。 第二密封元件包括具有一个或多个板的环可移动以适应提升管的热膨胀。
