Abstract

As a new absorbent for carbon dioxide, sodium glycinate (SG) was investigated in this study. The solubilities of CO₂ expressed as loading capacity (mol CO₂/mol SG) in aqueous 10, 20, and 30 mass% sodium glycinate solutions were measured experimentally at 303.15, 313.15, and 323.15 K over the partial pressure of carbon dioxide ranging from 0.1 to 200 kPa in an equilibrium cell. It was found that CO₂ solubility increases with decrease in concentration of sodium glycinate solution and with decrease in temperature. It also increases with an increase in partial pressure of CO₂ for the pressure range studied. The CO₂ solubility in 10 mass% sodium glycinate solutions was found to be better than other aqueous absorbents such as MEA, AEPD, AMPD, and TIPA. The net amount of CO₂ absorbed by 20 and 30 mass% sodium glycinate solution was almost same.
