Spent catalyst distributor

   
   

The present invention is related to methods and apparatus for improving distributions of both spent catalyst and transport gas into a regenerator of a fluid catalytic cracking unit. Spent catalyst and transport gases move upwardly through a spent catalyst riser and are diverted in a radially outward direction by a deflector cone. The catalyst and transport gas are re-mixed as they move radially outward between two disks before discharging from the outer edges (perimeter) of the distributor into the regenerator in a substantially uniform radial direction. The distributor is adapted to provide continuous discharge from its perimeter so as to cover the entire cross-section of the regenerator.

A invenção atual é relacionada aos métodos e ao instrumento para melhorar distribuições de catalizador gasto e de gás do transporte em um regenerator de uma unidade rachando catalytic fluida. Os gáses gastos do catalizador e do transporte movem-se ascendente através de um riser gasto do catalizador e são desviados em um sentido radial externo por um cone do defletor. O catalizador e o gás do transporte re-mixed enquanto se move radial para fora entre dois discos antes de descarregar das bordas exteriores (perímetro) do distribuidor no regenerator em um sentido radial substancialmente uniforme. O distribuidor é adaptado para fornecer a descarga contínua de seu perímetro para cobrir o cross-section inteiro do regenerator.
