    摘要: A method and apparatus are disclosed for removing water from a recycle gas stream in a catalyst regeneration process. A recycle gas stream contacts catalyst and the catalyst sorbs water from the recycle gas. Some of the now-dried recycle gas recirculates to the regeneration process, thereby decreasing the water content in the regeneration process. The catalyst containing sorbed water passes to a desorption zone, where water is desorbed from the catalyst and the desorbed water is rejected from the process. This method and apparatus are useful for extending the life of catalyst in catalytic hydrocarbon processes that employ continuous or semi-continuos catalyst regeneration zones.

    摘要: A method is disclosed for decreasing the emissions of chlorine-containing species from a moving bed process for regenerating spent catalyst particles with a recycle gas stream. A recycle gas stream contacts spent catalyst particles at regeneration conditions, thereby producing a flue gas stream. The flue gas stream which contains chlorine-containing species contacts spent catalyst particles at sorption conditions. The spent catalyst particles sorb the chlorine-containing species from the flue gas stream, thereby producing the recycle gas stream. A portion of the recycle gas stream is vented from the process. This method captures and returns to the process the chlorine-containing species that would be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of the process. This method is adaptable to many processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated in a moving bed.

    摘要: A method is disclosed for decreasing the emissions of chlorine-containing species from a process for contacting catalyst particles with a recycle stream containing chlorine-containing species. Prior to contacting the catalyst particles with the recycle gas, an effluent stream that contains chlorine-containing species contacts the catalyst particles at sorption conditions. The catalyst particles sorb the chlorine-containing species from the effluent stream. This method captures and returns to the process the chlorine-containing species that would be lost from the process and that would need to be replaced by the injection of make-up chlorine-containing species. This method results in a significant savings in capital and operating costs of the process. This method is adaptable to many processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.
