In this thesis, the saturated solubility, loading value and absorption rate were measured for CO2 in 2-amino-2-methyl-1-propanol?AMP? promoted K2CO3 aqueous solutions. The temperatures ranged from 303.2K to 323.2K. The viscosities of K2CO3-AMP aqueous solutions were also measured and then modeled by using the Weiland equation.Our results show that:?1? At given mass fraction of K2CO3 and temperature, with increasing mass fraction of AMP, the saturated solubility and CO2 loading respectively increases and decreases, however, the absorption rate also obviously increases;?2? At given mass fractions of K2CO3 and AMP, with increasing temperature, both the saturated solubility and CO2 loading decrease but the absorption rate obviously increases;?3? At given mass fraction of K2CO3 and temperature, the viscosity of K2CO3-AMP aqueous solution increases with the increase of the mass fraction of AMP;?4? At given mass fraction of K2CO3 and AMP, the viscosity of K2CO3-AMP aqueous solution decreases with increasing temperature;?5? At given mass fraction of AMP and temperature, the viscosity of K2CO3-AMP aqueous solution increases with the increase of the mass fraction of K2CO3;?6? The Weiland equation is able to correlate the viscosity of K2CO3-AMP aqueous solution, and the correlation agrees with experiment. |
