The solubility of carbon dioxide in 4.28 and 1.69 M aqueous methyldiethanolamine (MDEA) and 0.287 and 0.115 M N,N-bis(hydroxyethyl)piperazine (BHEP) solutions has been determined experimentally. The experimental conditions were 100–200 °C for MEDA, 40–180 °C for BHEP, and CO2 partial pressures of 172–4929 kPa. Mathematical models for predicting CO2 solubility in MDEA and BHEP solutions are presented. The model correlations agree well with present and previously published data.
