We studied the heats of reaction (ΔHr) and vapor−liquid equilibria for N-methyldiethanolamine and novel absorbents [1,2-dimethylimidazole, 2-methylimidazole, 1-methylimidazole, imidazole, and 4-(2-hydroxyethyl)morpholine] obtained by the pKa-based screening method in our previous work and found a proportional relationship between pKa and ΔHr values. This allows estimation of ΔHr values by measuring their pKa. Measurements of vapor−liquid equilibria of novel absorbents provided important information on the CO2 capacity per absorption/recovery cycle. 1,2-Dimethylimidazole and 4-(2-hydroxyethyl)morpholine would be nominated as candidates suitable to absorb/recover CO2 with partial pressures at 1.6 MPa or higher without loss of a CO2 pressure level, resulting in saving CO2 compression energy in the CCS process.
