ABSTRACT:
Apparatus for regenerating at elevated temperature a fluidized mass of particles, e.g., a catalyst used in treatment of hydrocarbons, e.g., fluidized catalysts cracking of oil, is disclosed.
Several operations can be effected in the apparatus, each of them alone or in various combinations.
An operation basic to the overall operation, always effected by the apparatus, is the continuous circulation of dense phase particles undergoing regeneration from a dense phase or fluidized regeneration vessel to a hot surge vessel and from the latter back into the dense phase bed in the regeneration vessel.
Used catalyst can be in part passed to the hot surge vessel whenever it is tending to cause undue temperature rise in the regeneration vessel.
Fresh or unused catalyst can be fed to the regeneration vessel continuously or intermittently responsive to sensed temperature change in said vessel and/or to said hot surge vessel.
A temperature sensing controller station resets a level controller, controlling regeneration vessel dense phase bed level by controlling the several possible flows or combinations thereof.
