Abstract:
1. A catalyst regenerator vessel for combusting carbonaceous deposits from catalyst comprising: a first chamber including a catalyst inlet for feeding spent catalyst with carbonaceous deposits to said first chamber and a combustion gas distributor for distributing combustion gas into said first chamber to contact said spent catalyst and combust carbonaceous deposits to provide at least partially regenerated catalyst and generate flue gas; a riser section extending from said first chamber for transporting regenerated catalyst and flue gas, said riser section comprising an outer wall, at least one opening in said outer wall, and at least one disengaging arm radially extending about said opening from said outer wall, said disengaging arm comprising an outer shell that encloses the arm, and an inner shell with a slot for allowing catalyst and flue gas to exit the arm, said outer shell having a horizontal section, a turned section being turned downwardly as its length extends from the horizontal section and a vertical baffle having a lower edge located below said opening in said outer wall, said vertical baffle for directing said catalyst and flue gas downwardly and minimizing radial flow; and a second chamber containing said disengaging arm, said second chamber including a cyclone separator for separating catalyst from combustion gas, a regenerated catalyst outlet and a flue gas outlet.
