Estudo do processo de absorção de CO2 em soluções de aminas empregando-se coluna recheada.

TL;DRAbstract

The aim of the present work was to characterize and study the mass transfer process of the CO 2 absorption into single and blended alkanolamines in a packed column under atmospheric pressure. For this purpose, two systems were built, one of the columns is a laboratory structure packed column and the other is a pilot random packed column. The absorption of CO 2 into NaOH was performed to determine the effective mass-transfer area and the overall mass-transfer coefficient. The absorption performance was evaluated in terms of the overall mass-transfer coefficient for the absorption of CO 2 in air into single and blended alkanolamines: MEA 25% wt, and MEA-MDEA mixtures, MEA-MDEA (25% /5% wt), MEA-MDEA (20% /10% wt) and MEA-MDEA (15% /15% wt). The CO 2 absorption performance of MEA-MDEA mixture has a high correlation with the proportion MEA-MDEA. Experimental series were designed employing a process simulator for the hydrodynamic checking and determination of gas and liq flow rates. Compari
