Abstract

Se describe un sistema de selladura de pierna de ciclon separador de solidos en suspensiones gas-solido. Más específicamente, la presente se refiere a unsistema de selladura de piernas de dos estaciones de ciclones en serie utilizadas en los procesos de craqueamiento catalítico fluido (FCC), comprendiendo unaconfiguracion terminal, que comprende el empleo de una curva (31) de radio largo desprovista de partes moviles, que cambia la direccion del flujo másicodescendente del catalizador en fase de nsa, en un plano ortogonal a un flujo gaseoso ascendente que impide una entrada de fase gaseosa hacia o al interior de lapierna (24), promoviendo una selladura eficiente y al mismo tiempo, evitando atrancamiento del lecho denso de particulados.
