Using software developed in Matlab and existing knowledge of chemical equilibria, investigations into the fundamental properties of formulated amine solvents and their interaction with CO2 have been carried out. A simple solvent formulation containing equimolar amounts of monoethanolamine (MEA), Amine 1, and a sterically hindered /tertiary amine, Amine 2, has been investigated here. Specifically, the role of Amine 2 in the overall equilibrium behaviour of amine blends is discussed. Systematic variations of the protonation constants and reaction enthalpies of Amine 2 over a range of typical values has revealed that significant improvement can be made in terms of absorption capacity, cyclic capacity, and overall absorption enthalpy in the blends when compared to the standard 5.0 M MEA solvent.]]> Wed 11 Apr 2018 14:03:51 AEST ]]> A systematic investigation of carbamate stability constants by ¹H NMR https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18149 Sat 24 Mar 2018 08:04:41 AEDT ]]>
