Adsorption of CO2 into Slurries(III)-The Absorption of CO2 into Laminer Falling Films of Slurries of Kaolin and White Carbon with HaOH-
박상수, 김성수
젖은 벽탑을 사용하여 20℃, 1atm에서 NaOH 수용액에 CO2 기체를 흡수시켜 기-액 접촉 시간을 변화시키면서 CO2의 흡수속도를 측정하였다. 실험결과는 침투설을 근거로 한 반응흡수 이론에 의해 해석하엿으며, 반응촉진 인자의 실험치가 CO2와 OH-와의 비가역 2차 반응을 동반하는 흡수에 대한 대류-확산 방정식의 근사 이론치와 평균 편차 8%이내에서 일치하였다. Power-law 거동을 나타내는 NaOH-kaolin slurry 계와NaOH-white carbon slurry 계의 비뉴튼액체에서의 화학습수기구는 비뉴튼액체의 특성치인 power-law index와 consistency index를 가미한 뉴튼액체에서의 화학흡수기구를 사용하여 설명할 수 있었다.
The absorption rate of carbon dioxide into laminar falling films of aqueous NaOH solution, NaOH-kaolin slurry and NaOH-white carbon slurry was measured by various changes of contact time between gas and liquid using a wetted-wall column at 20℃. The experimental data were analyzed by the penetration theory based on the gas absorption with second-order ir-reversible chemical reaction between CO2 and OH-. The measured reaction enhancement factors were consistant with those predicted by the approximate equation (14) derived by the convective-diffusion equation within an average deviation of 8, 7.8 and 9.3% in the NaOH, NaOH-kaolin slurry and NaOH-white carbon slurry, respectively. The mechanism of gas absorption with reaction into Newtonian liquid could be also used in the case of power-law liquids.
