Original Abstract Submitted
Processes for regenerating catalyst from a fluidized catalytic process and purifying the flue gas are described. The process involves incorporating a combined quench/polishing column into the catalyst regeneration and flue gas purifying process. The combined quench/polishing column is located after the filtered dry SOx reactor effluent stream is cooled. The cooled effluent stream is quenched in the quench section of the combined quench/polishing column to form a quenched stream, and a second reactant is contacted with the quenched stream in the polishing section of the combined quench/polishing column to form a liquid stream and a purified outlet gas stream with a reduced temperature compared to the cooled effluent stream.
