- ABSTRAK This study investigates mass transfer coefficient and reaction rate constant in the absorption of CO2 into aqueous solution of KOH. The experiments were carried out by bubbling CO2 from the bottom of a stirred tank containing KOH solution. The inner diameter of the stirred tank was 14 cm and the depth was also 14 cm. The tank was equipped with 4 baffles each of 2.5 cm in width and 12 cm in height. The stirrer was a flat blade agitator of 5'cm in length and 1.5 cm in width. The sparger was made of copper pipe with the holes diameter of 1.5 mm. The effects of KOH concentration in the solution and operating temperature on mass transfer coefficient and reaction rate constant have been studied. The effect of KOH concentration (GB4O) on the mass transfer coefficient (K1) can be expressed as Kr, = 0.0001 7 In C7,0 + 0.01 79, in the range of CA0 of 0.0752 to 0.3445 gmol/L. The relative mean error for this expression is 1.92%. The correlation between the chemical rate constant ac��) with the operating temperature (T) is k�,� = 107.exp (-11,501.75/RT), for the operating temperature of 303 to 333 K with the relative mean error of 3.78%.
