Abstract

La presente invención es aplicable, especialmente, a sistemas de ciclón de tercera etapa, equipo usado normalmente junto con ciclones de cuarta etapa para reducir la concentración de partículas de catalizador en los gases de combustión de unidades de Termodesintegración Catalítica de Fluidos (FCC). La invención se refiere a un proceso donde la corriente de purga del recipiente de tercera etapa de ciclón se remueve continuamente de la parte superior del recipiente de tercera etapa, usando la longitud extensa de este recipiente para introducir un paso de separación natural, donde las partículas 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 separación global del sistema, que es una alternativa de más bajo costo en comparación al uso de filtros de bloqueo total.The present invention is applicable, especially, to third stage cyclone systems, equipment normally used in conjunction with fourth stage cyclones to reduce the concentration of catalyst particles in the combustion gases of Fluid Catalytic Thermocracking (FCC) units. The invention relates to a process where the purge stream from the third stage cyclone vessel is continuously removed from the top of the third stage vessel, using the extensive length of this vessel to introduce a natural separation step, where the particles present in this stream are released from the gas that rises to the container at low speed, returning to the bottom of the container. The material collected by the third stage cyclones is accumulated in the container cone, which is discarded therefrom at regular intervals. This process proposes to increase the overall separation efficiency of the system, which is a lower cost alternative compared to the use of total blocking filters.
