Title
(EN) REMOVABLE FILTER FOR SLURRY HYDROCARBON SYNTHESIS PROCESS
(FR) FILTRE AMOVIBLE POUR PROCEDE DE SYNTHESE D'HYDROCARBURES EN BOUE
Abstract
(EN)
A removable filter for separating and filtering slurry liquid from solid particles includes one or more filter sections connected by a filtrate conduit. Each section comprises a plurality of vertical, hollow, sintered metal filter elements horizontally arranged across a manifold connected to a hollow filtrate conduit. The sections are vertically stacked and connected by the conduit(s) t o form the filter which is removably secured in the slurry by means which permit it to be removed vertically up and out of the top of the reactor. This filter has a high surface area to volume ratio and is useful for removing the liquid hydrocarbon products from a slurry hydrocarbon synthesis reactor and can easily be replaced without having to drain out the slurry.
(FR)
Cette invention concerne un filtre destiné à filtrer et à séparer les particules liquides des particules solides d'une boue, ledit filtre comprenant une ou plusieurs parties de filtre reliées entre elles par un conduit à filtrat. Chaque partie comprend une pluralité d'éléments de filtres en métal fritté, creux et verticaux, qui sont disposés horizontalement à travers un collecteur connecté à un conduit à filtrat creux. Les parties sont empilées verticalement et reliées par le(s) conduit(s) pour former un filtre amovible fixé dans la boue au moyen d'organes lui permettant d'être soulevé verticalement et extrait par le dessus du réacteur. Ce filtre possède un rapport surface/volume important. Il est utile pour éliminer les produits hydrocarbures liquides d'un réacteur de synthèse d'hydrocarbure en boue et il est facile de le remplacer sans avoir à drainer la boue.
