Kinetic Modelling and Simulation of Carbon Dioxide Absorption into Aqueous Ammonia Solution

Nowadays, the amount of greenhouse gases in the atmosphere is nearly on the verge of alarming and one of the main components which is of highest the abundance is carbon dioxide (CO2). Therefore, it is imperative that its emission be reduced. Through absorption, alkanolamines have been widely focused...
