Experimental Study of Carbon Dioxide Capture from Synthetic Industrial Incinerator Flue Gas with a Pilot and Laboratory Measurements

In this study, we evaluate the sustainability of absorption/desorption technology for CO2 capture from a targeted unit specialized in industrial waste incineration. The purpose of our study is to fill in this shortage by using a pilot set-up to investigate chemical interactions between synthetic flue gas and solvents and their impacts on process performance. At the same time, we complete our prospection by laboratory experiments to study the influence of specific degradation products on process performance. In this paper, we choose to focus on gas absorption. First, we provide our feedback on experimental methods for overall mass transfer coefficient (KGaW) measurements for CO2 absorption. Second, absorption of acidic pollutants, leading to heat stable salts formation, was investigated. Therefore, we used laboratory tools to study the influence of these salts on process performance.
