Using solid phase extraction (SPE) combined with HPLCfluorescence/photodiode array (PDA) detection several low molecular-weight alkylamines (including ethylamine and propylamine) have been detected in the gas-phase, released during the oxidative/thermal degradation of monoethanolamine (MEA), an amine-based postcombustion CO2 capture solvent. In this study, a 30 wt% aqueous MEA solution was degr...

Post-combustion carbon capture is a key component of the fight against global warming and climate change. Amine stripping is currently the leading post-combustion technology, and indeed is employed at the World’s first and only commercial scale carbon capture project applied to a power plant, at Boundary Dam, Canada. Normally, regeneration of the spent amine solution is achieved by stripping wi...

Pregnant Sprague-Dawley rats and New Zealand White rabbits were exposed dermally to 0, 10, 25, and 75 mg/kg/day of monoethanolamine (MEA) for approximately 6 hr/day on Days 6 through 15 (rats) or 6 through 18 (rabbits) of gestation. A fifth dose group of 225 mg MEA/kg/day was evaluated in rats only. Dermal exposure of pregnant rats to 225 mg/kg/day and rabbits to 75 mg/kg/day resulted in signif...

Nano-composite copper-zinc oxide (NCCZO) was deposited on borosilicate glass using a novel sol-gel/doctor-blade technique. The photocatalyst was prepared from copper acetylacetonate, zinc acetylacetonate, monoethanolamine (MEA) and citric acid monohydrate at 75 oC, aged for 1 d and annealed at 650 oC. The properties of the NCCZO nano-composite were investigated by X-ray diffraction (XRD) and fi...

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...
