The theory of absorption accompanied by pseudo first order reaction was used to evaluate effective mass transfer area, a and liquid side mass transfer coefficient, $K_L$ as a function of liquid flow rates and size of packing materials in a randomly packed column. The system used was that $CO_2$ gas was absorbed into carbonate-bicarbonate buffer solutions containing hypochlorite as catalyst.
The experimental results showed that the dependency of interfacial area and mass transfer coefficient on system characteristics were found to be as follows;
$a=1.474L^{0.380} D_p^{-0.754}$
$K_L=1.97\times10^{-2}L^{0.208} D_p^{0.747}$
These values were compared with the data of $k_La$ in literature and found good agreement with each others.
유효 물질 전달 면적 (effective mass transfer area, a) 과 액측 물질 전달 계수 (liquid phase mass transfer coefficient, $k_L$) 를 액체유속 (liquid flow rate, L) 과 충진물의 크기의 함수로 나타내기 위하여 12cm I.D. randomly packed column 에서 pseudo first order reaction 에 의한 흡수이론이 사용되었다. 즉 $CO_2$ gas 를 hypochlorite 를 촉매로 하여 potassium carbonate - bicarbonate buffer solution 에 흡수시키는 방법을 사용하였으며, 실험결과는 물성에 따른 유효물질 전달 면적, a와 액측 물질 전달 계수, $k_L$ 의 변화가 다음 식으로 표시할 수 있었다.
$ a = 1.474 L^{0.380} D_p^{-0.754}$
$ k_L = 1.97 × 10^{-2} L^{0.208} D_p^{0.747}$
그리고 이들 값들은 문헌에 나타난 $k_La$ data 와 비교 검토하였을 때 비교적 잘 일치함을 알았다.
