Abstract
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.
