Abstract

La presente invencion es aplicable, especialmente, a sistemas de ciclon de tercera etapa, equipo usado normalmente junto con ciclones de cuarta etapa para reducir la concentracion de particulas de catalizador en los gases de combustion de unidades de Termodesintegracion Catalitica de Fluidos (FCC). La invencion se refiere a un proceso donde la corriente de purga del recipiente de tercera etapa de ciclon se remueve continuamente de la parte superior del recipiente de tercera etapa, usando la longitud extensa de este recipiente para introducir un paso de separacion natural, donde las particulas presentes en esta corriente se liberan del gas que asciende al recipiente a baja velocidad, retornando a la parte inferior del recipiente. El material recolectado por los ciclones de tercera etapa se acumula en el cono de recipiente, que se descarta del mismo a intervalos regulares. Este proceso propone incrementar la eficiencia de separacion global del sistema, que es una alternativa de mas bajo costo en comparacion al uso de filtros de bloqueo total.
