Abstract
2-amino-2-methyl-1-propanol (AMP) in dimethyl sulfoxide (DMSO) is a
precipitating non-aqueous amine technology that can potentially lower
the energy demand during CO2 removal from industrial flue gases compared
to aqueous amine technologies. However, DMSO is hygroscopic and has a
high possibility of absorbing water from humid flue gases, which can
affect the physical properties of the system, such as the heat capacity.
In this study, the heat capacity was measured for solutions of 25 wt%
AMP in DMSO with 0, 10, and 25 wt% water at 30, 70 and 85°C using a
reaction calorimeter. The heat capacity was not significantly affected
by the temperature; however, the water content of the solution had a... (More)

reaction calorimeter. The heat capacity was not significantly affected
by the temperature; however, the water content of the solution had a
significant effect on the heat capacity. In general, an increased water
content resulted in a higher heat capacity. Hence, the effect of water
accumulation on the heat capacity of this system is something that needs
to be considered when designing heat transfer equipment using this
technology at a larger scale. (Less)
