Popis:	Carbon dioxide was absorbed into aqueous polyacrylamide (PAA) solution containing diethanolamine (DEA) of 0–2 kmol/m 3 in a flat-stirred vessel with the impeller of 0.034 m and agitation speed of 50 rpm at 25 °C and 0.101 MPa to measure the absorption rate of CO 2 . The volumetric liquid-side mass transfer coefficient ( k L a ) was obtained from the dimensionless empirical correlation formula presenting the rheological behavior of aqueous PAA solution. PAA with elastic property of non-Newtonian liquid made the rate of chemical absorption of CO 2 accelerate compared with Newtonian liquid based on the same viscosity of the solution. The estimated value of the absorption rate of CO 2 was obtained from the model based on the film theory accompanied by chemical reaction and compared with the measured value.
