A method for separating and filtering solid particles from a hydrocarbon slurry liquid includes two or more filter sections in fluid communication with the hydrocarbon slurry. At least one filter section is comprised of one or more filter elements having a mean pore size of less than 10 microns, and at least one other section is comprised of one or more filter elements having a mean pore size of 10 microns or greater. The small pore filter (less than 10 microns) will exclude all or substantially all of the smaller catalyst fines produced by catalyst particle attrition. The liquid product removed from the small pore filters will be substantially free of particulates. The large pore filters (10 microns or greater) will exclude larger catalyst particles, but will allow the smaller fines to pass. The liquid product removed from the large pore filters will contain the fines generated from catalyst particle attrition.
Procédé de séparation et de filtration de particules solides à partir d~un liquide de boue d~hydrocarbure comportant deux ou plus de deux sections filtrantes en communication fluide avec la boue d~hydrocarbure. Au moins une section filtrante se compose d~un ou plusieurs éléments filtrants d~une taille de pore moyenne inférieure à 10 microns, et au moins une autre section se compose d~un ou plusieurs éléments filtrants d~une taille de pore moyenne supérieure ou égale à 10 microns. Le filtre à petits pores (inférieurs à 10 microns) exclura toutes ou sensiblement toutes les plus petites fines catalytiques produites par attrition particulaire catalytique. Le produit liquide retiré des filtres à petits pores sera sensiblement exempt de matières particulaires. Les filtres à gros pores (supérieurs ou égaux à 10 microns) excluront les particules catalytiques plus grosses, mais laisseront passer les plus petites fines. Le produit liquide retiré des filtres à gros pores contiendra les fines générées par l~attrition particulaire catalytique.
