A systematic investigation of the equilibrium solubility of CO2 in aqueous piperazine solutions was conducted in a double-jacketed stirred cell reactor. The solubilities of CO2 in the solution were measured at 20, 30, 40, and 50 °C with CO2 partial pressures ranging from 0.4-95 kPa. Generally the a...
