ABSTRACT:
The invention here disclosed is a novel apparatus and method for the separation of solid and fluid phases in a horizontal elongated cyclone separator with a novel inclined solid dropout continuous and uninterrupted slot in the bottom to transfer a solid phase via primary mass separation from either an upflow or a downflow reactor in the initial portion of the cyclone separator to a downcomer which may be equipped with a stripping function. The instant horizontal elongated cyclone separator is constructed to ensure an elongated helical flow path of the vapor phase with a minor portion of the catalyst particles therein from one end of the cyclone separator to a withdrawal conduit to disengage via secondary centrifical separation a minor portion of the solid phase from the fluid phase. The minor portion of the solid phase is thereafter transmitted to the stripping function by a vertical downcomer interconnecting the stripping function and the bottom of the horizontal elongated cyclone separator. The entire apparatus is constructed so that the tangential velocity of the fluid across the upper section or lower section of the reactor tube divided by the superficial axial velocity of fluid across the cross section of the withdrawal conduit is greater than 0.2 which guarantees formation of the vortex in the horizontal elongated cyclone separator.
