Étude de l’effet des impuretés sur la dégradation des alcanolamines utilisées dans un procédé de captage du dioxyde de carbone issu des fumées d’incinérateur de déchets industriels

摘要

In the context of industrial symbiosis, the goal of this project is to reuse the carbon dioxide from the incinerator gas as a commercial substance. The most suitable technology of CO2 capture from postcombustion gas is the chemical absorption by alkanolamines. Some characteristics of waste incinerator gas may affect the performances of CO2 capture process. The composition of gas from industrial waste incinerator plant is characterized by a high concentration of oxygen and the presence of NOx and SOx. The first goal is to determine the influence of pollutants like NOx and SOx on the degradation of the amine and the second objective is to study the impact of pollutants on the CO2 absorption kinetics in a solvent.
