Title (EN) METHOD FOR PROCESSING GASEOUS WASTES CONTAINING ORGANIC COMPOUNDS BY CAPTURING OR CONDENSATION
(FR) PROCEDE DE TRAITEMENT D'EFFLUENTS GAZEUX CONTENANT DES COMPOSES ORGANIQUES PAR CAPTAGE OU CONDENSATION
Abstract:
(EN) The invention relates to a method for processing and depolluting gaseous wastes containing volatile organic compounds (COV) and/or polycyclic aromatic hydrocarbons (HAP) by adsorption and/or condensation by powder mineral particles, consisting (c) in introducing powder alumna particles in a gaseous waste flow, wherein at least one part of the COV and / or HAP are deposited on the particles, (d) in separating the powder alumna particles loaded with the COV and / or HAP from the processed gaseous wastes. The inventive method is characterised in that (1), prior to the stage (c) for introducing the powder alumna particles, at least one stage for pre-cooling the treatable wastes in inserted, and (2) at the stage (c) for introducing the powder alumna particles, the used particles are cooled prior to the introduction thereof.
(FR) L'invention concerne un procédé de traitement de dépollution d'effluents gazeux contenant des composés organiques volatils (COV) et / ou des hydrocarbures aromatiques polycycliques (HAP), par adsorption et/ou condensation par des particules minérales pulvérulentes, comportant successivement : (c) une étape d'introduction de particules pulvérulentes d'alumine dans les flux des effluents gazeux, au cours de laquelle dite étape au moins une partie desdits COV et / ou HAP se déposent sur lesdites particules ; (d) une étape de séparation des particules pulvérulentes d'alumine chargées des COV et/ou HAP et des effluents gazeux traités ; et caractérisé en ce que (1) avant l'étape d'introduction des particules pulvérulentes d'alumine (c), est insérée au moins une étape de pré-refroidissement des effluents à traiter ; (2) dans l'étape d'introduction de particules pulvérulentes d'alumine (c), les particules mises en œuvre sont refroidies avant leur introduction.
