Pilot Plant Studies for CO₂Capture from Waste Incinerator Flue Gas Using MEA Based Solvent

Abstract

Experimental study of carbon dioxide (CO<sub>2<sub/>) 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 <i>K<i/><sub><i>G<i/><sub/><i>a<i/><sub><i>w<i/><sub/> 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<sub>2<sub/> and SO<sub>2<sub/> absorption through the solvent as well as the accumulation of Heat Stable Salts (HSS) for a full scale CO<sub>2<sub/> capture unit fed by a waste incinerator flue gas.
