Re´sume´-É tude du captage du CO 2 dans des gaz de combustion d'un incine´rateur de de´chets al 'aide d'un pilote utilisant un solvant a`base de MEA -L'e´tude e´value la faisabilite´du captage du dioxyde de carbone (CO 2 ) dans des gaz de combustion d'un incine´rateur de de´chets spe´ciaux. Un pilote a`l'e´chelle laboratoire a e´te´mis en oeuvre pour e´tudier le proce´ded 'absorption/de´sorption du CO 2 par un solvant a`base de MonoEthanolAmine (MEA). L'e´tude a e´te´conduite en laboratoire et sur un site industriel. L'installation expe´rimentale est instrumente´e pour obtenir des bilans de matie`re avec pre´cision. Une e´tude parame´trique en laboratoire a permis de mesurer le coefficient de transfert global K G a w pour plusieurs re´gimes de fonctionnement du pilote. Des expe´riences de longue dure´e, en laboratoire et sur site industriel, ont analyse´la re´sistance chimique de la MEA au gaz de combustion d'un incine´rateur. Ces expe´riences ont e´galement permis d'e´tudier l'absorption du dioxyde d'azote NO 2 et du dioxyde de soufre SO 2 dans le solvant de captage. Elles ont abouti a`une estimation de la cine´tique d'accumulation de sels stables dans un solvant a`base de MEA confronte´a`des gaz de combustion d'un incine´rateur.Abstract -Pilot Plant Studies for CO 2 Capture from Waste Incinerator Flue Gas Using MEA Based Solvent -Experimental study of carbon dioxide (CO 2 ) capture from waste incinerator flue gas is presented. A specific pilot plant has been achieved based on absorption/desorption process using MonoEthanolAmine (MEA) solvent. Several experiments have been carried out at laboratory and industrial site. The pilot is fully instrumented to establish precise balances. Laboratory experiments allow to measure overall mass transfer coefficient K G a w for several pilot operating conditions. Long laboratory and industrial runs provide an estimation of MEA chemical resistance against waste incinerator flue gas. The experiments also allowed the analysis of NO 2 and SO 2 absorption through the solvent as well as the accumulation of Heat Stable Salts (HSS) for a full scale CO 2 capture unit fed by a waste incinerator flue gas.
