PROCESS AND APPARATUS FOR SIMULTANEOUSLY REGENERATING AND COOLING FLUIDIZED PARTICLES |
摘要 |
FCC catalyst regeneration by introducing a first stream of oxygen-contg. combustion gas and the fluidised catalyst particles into a combustion zone to produce hot fluidised particles; passing these upward into a second zone above the combustion zone and collecting a dense phase bed of hot solid particles in a collection section at the bottom of the second zone; transferring a stream of particles downward through a particle flow means and a vertical transfer conduit into the upper end of a backmixed particle cooling chamber; cooling the particles in a lower portion of the cooling chamber using a heat exchanger entirely within the lower part of the cooling chamber; fluidising the dense phase particle bed by the passage of a controlled flow of a second oxygen-contg. combustion gas, and discharging the second stream of combustion gas into the combustion zone through a conduit above the heat exchanger. |
