ABSTRACT:
An apparatus for regenerating coke-contaminated fluid catalyst which comprises a vertical combustion chamber, an inlet to said chamber for spent catalyst and regeneration gas, a disengagement chamber above and in communication with the combustion chamber, a heat removal chamber below the combustion chamber in which may be maintained a dense phase catalyst bed, heat removal means positioned within the heat removal chamber such that it will be immersed in the catalyst bed, a recycle conduit for passing catalyst from the disengagement chamber to the heat removal chamber, a vertical cooled catalyst inlet conduit connecting the heat removal chamber with the lower portion of the combustion chamber so that catalyst can pass from the former to the latter, and a regeneration gas inlet line connecting with a lower part of the cooled catalyst inlet conduit to enable the flow of cooled catalyst up into the combustion chamber, wherein a control system senses the catalyst level in the heat removal zone, formulates an output signal via a level control means having an adjustable set point, and regulates the flow rate of regeneration gas into the cooled catalyst inlet conduit via transmission of the output signal to a flow control means responsive thereto and thereby controls such level.
