Carbon Dioxide Reaction Kinetics and Transport in Aqueous Amine Membranes

VLE data and modelling of aqueous N,N-diethylethanolamine (DEEA) solutions

“…In this context, the reactive absorption of CO 2 by tertiary amine solutions has been investigated. As first proposed by Donaldson and Nguyen (1980), tertiary amines promote the reaction of hydration of CO 2 , leading to bicarbonate formation. The heat of formation of bicarbonates is lower than that of carbamates (formed when using primary and secondary amines).…”

“…As first proposed by Donaldson and Nguyen (1980), tertiary amines promote the reaction of hydration of CO 2 , leading to bicarbonate formation, as in equation 6 2 2 3…”

Dynamic simulation of MEA absorption process for CO2 capture from power plants

“…The reaction mechanism of tertiary amine with CO 2 is described as base-catalyzed hydration as proposed by Donaldson and Nguyen (1980). This can be represented as follows,…”

Reaction kinetics of CO2 in aqueous methyldiethanolamine solutions using the stopped-flow technique

“…In contrast, tertiary alkanolamines do not react directly with CO 2 to form carbamates. In aqueous solutions, tertiary amines catalyse CO 2 hydrolysis to form bicarbonate ions and the protonated amine as was firstly proposed by Donaldson and Nguyen (Donaldson and Nguyen, 1980). Tertiary amines have a high CO 2 loading capacity of 1 mol CO 2 /mol amine.…”
