Title (EN) PROCESS FOR TREATING WASTE GASES
(FR) PROCEDE DE TRAITEMENT DE GAZ PERDUS
Abstract: front page image
(EN)In a waste gas washing apparatus having absorption sections to which liquid chemicals are supplied for gas-liquid contact, fresh chemicals are replenished to the absorption section located at the nearest part to a gas outlet, and the chemicals are mixed with the circulating chemicals successively in absorption sections beginning with those closer to the gas inlet. According to this process, the waste gases at their saturation temperatures above 75 C may be treated effectively with a reduced amount of waste water.
(FR)Dans un appareil de lavage de gaz perdus ayant des sections d"absorption sur lesquelles on envoie des produits chimiques liquides en vue d"etablir un contact gaz-liquides, la section d"absorption la plus proche d"une sortie de gaz est alimentee en produits chimiques nouveaux qui se melangent aux produits chimiques circulant successivement dans les sections d"absorption en commencant par celles les plus proches de l"entree du gaz. Selon ce procede, les gaz perdus a leur temperature de saturation au-dessus de 75 C peuvent etre traites efficacement avec une quantite reduite d"eau perdue.
