The highest bicarbonate formation enables DACH-MDEA blend to reduce the regeneration energy. The DACH-MDEA blend also shows the highest CO2 loading (0.576 mol CO2/mol amine) at low CO2 partial pressure. According to the investigation of corrosion behaviours of these three CO2-loaded amine blends, the corrosion rate is PZ-MDEA ≈ DACH-MDEA ≪ MEA-MDEA. All of the results indicate that the DACH diamine with cyclic structure is a promising promoter. This work investigates the effect of amine structural features on the CO2 absorption performance, which provides more knowledge to design efficient amine solvents for CO2 capture.]]> Wed 03 Aug 2022 14:40:18 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27126 carb=7600M^-1s^-1 at 35°C and Eₐ=38 kJ mol^-1) and similar carbamate stability but with a ~40% larger enthalpy of protonation. It was also found to be less corrosive and have lower viscosity and heat capacity. Significant performance gains relative to MEA 30wt% were predicted by using BZA in a formulation with either MEA or 2-amino-2-methyl-1-proponal (AMP) with predicted reductions in reboiler duty up to 13%, improvements in mass transfer up to 20% and low corrosion potential.]]> Sat 24 Mar 2018 07:41:34 AEDT ]]>
