Abstract

Procédé et appareil pour la séparation de particules à partir d'un fluide les contenant. On fluidise une couche de solides fluidisables au moyen de fluide contenant les fines, dans des conditions telles que ce fluide ne jaillisse pas en jets au sommet du lit, les solides du lit étant de préférence une centaine de fois plus gros que les particules et étant revêtus d'une substance dont le collage se modifie au cours du temps de séjour dans le lit. Les particules adhèrent aux solides momentanement collants et on peut les récupérer pour les réutiliser. Application à l'épuration de gaz poussiéreux et à la récupération de catalyseur entraîné par des gaz de combustion de craquage.
