Abstract
Vent gases from a catalyst cooler are directed downstream or outside of the catalyst regenerator to avoid sending air to a location where after burn may occur. Vent gases contain oxygen that when contacted with carbon monoxide in regenerator flue gas can cause after burn to occur at a location which lacks sufficient catalyst density to serve as a heat sink. Locating the cooling media supply in the top of the catalyst cooler enables cooled catalyst to drain from the bottom of the catalyst cooler and fitting more cooler tubes in the catalyst cooler.
