Abstract

The solubility of CO2 in various aqueous amine based solvents was determined at lower CO2 partial pressures. Cyclic capacity of various potential aqueous amine based solvents at 10 kPa CO2 partial pressure was determined by performing CO2 absorption at 30 ∘C, regeneration at 90oC and at 1 atmosphere. 1,7-Diaminoheptane and 1,6-Hexanediamine, N,N’-dimethyl was found to be having high cyclic loading of 0.81 and 0.85 moles CO2/moles amine respectively. Aqueous solution of 1,6-Hexanediamine, N,N’-dimethyl of 0.5 and 2.55 Mole/L concentration was selected for solubility study of CO2 at different partial pressure ranging from 1 up to 40 kPa, 30 ∘C and at 1 atmosphere. The solubilities of CO2 in aqueous 1,6-Hexanediamine, N,N’-dimethyl at 30oC were compared with those in aqueous solution of MEA with similar solution concentrations. The solubility of CO2 in 2.55 Mole/L 1,6-Hexanediamine, N,N’-dimethyl was found to be higher when compared to the 2.5 Mole/L MEA at lower CO2 partial pressure.
