摘要：The solubilities of CO2 in solvent poly(ethylene glycols) (PEGs) with molecular weights of 150, 200, 300, and 400 were measured over the range of pressure from (100 to 1200) kPa and temperature from (303.15 to 333.15) K. Henry's constant was obtained by linear fitting of the experimental data, and thermodynamic properties of solutions were calculated from the correlation of Henry's constant. It indicates that the solubility of CO2 increases with increasing molecular weights of PEGs. Henry's constant based on mole fraction and the molality of CO2 in PEG400 vary from (4.78 to 7.09) MPa and (1.56 to 2.48) MPa.kg.mol(-1) from (303.15 to 333.15) K, respectively.
