Title: Experimental Study on CO2 Absorption and Regenation of Aqueous Solutions of Potassium Glycinate
Abstract: Absorption of CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> with amines has been extensively studied in recent years because of environmental concern of global warming. The investigation of CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> absorption by potassium glycinate (PG) aqueous solution with different concentrations (1.0~3.0 mol/L) was conducted in a CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> absorber, and the regeneration performance of PG aqueous solution after CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> absorption by means of heating was studied. And the absorption performance difference between PG aqueous solution and several other commonly used aqueous alkanolamine solutions were discussed. The results showed that CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> absorption of PG aqueous solution was higher than that of MDEA aqueous solution and was little lower than that of MEA aqueous solution. The PG aqueous solution with higher concentration had higher absorption capacity, whereas lower absorption liquid CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> loading. Among three kinds of concentration, regeneration rate of 1 mol/L PG aqueous solution was highest. Regeneration rate of PG aqueous solution was better than that of MEA aqueous solution and lower than that of MDEA aqueous solution.
