The experimental study on the mechanism of CO2 absorption and desorption was tested by two kinds of glycinate (SG and PG) with TEA. The absorption and regeneration of CO2 by mixed absorption liquid were tested and compared with each other. The results showed that a low concentration of TEA in the SG and PG increased CO2 absorption capacity of mixed absorption solution. Addin more TEA on PG or SG lowered CO2 absorption capacity of mixed absorption solution. Desorption of PG didnt change with TEA. The low concentration of TEA had a role in promoting the desorption of mixed absorption solution (SG+TEA), and the high concentration of TEA inhibited the desorption of mixed absorption solution (SG+TEA).
