Abstract
<B>SISTEMA DE SELAGEM DE PERNA DE CICLONE<D> Descreve-se um sistema de selagem de perna de ciclone separador de sólidos em suspensão gás-sólido. Mais especificamente, a presente invenção diz respeito a um sistema de selegem de pernas de dois estágios de ciclones em série utilizados nos processos de craqueamento catalítico fluido (FCC), compreendendo uma configuração terminal, que faz emprego de uma curva (31) de raio longo desprovida de partes móveis, que muda a direção do escoamento do fluxo mássico descendente de catalisador em fase densa, em um plano ortogonal ao fluxo gasoso ascendente que impede a entrada de fase gasosa para o interior da perna (24), promovendo uma selagem eficiente, evitando o "empacotamento" do leito denso de particulados.
