초록

산업충전물로서 응용 가능성이 큰 망사 충전물의 특성을 파악하기 위하여 차아염소산소다 촉매를 함유한 탄산칼륨-중탄산칼륨 완충용액으로 이산화탄소 흡수 속도를 측정하여 물질전달계수, 기-액간 접촉계면을 살펴보고 액체 체류량, 압력강하 등의 특성을 살펴 보았다. 사용한 망사개공 크기는 검증용 완충용액의 물성을 감안하여, 50, 60mesh의 스테인레스 망사를 사용하였고, 그 형태는 충전물의 표면적을 산출할 수 있도록 구형으로 제작하였다. 구형 망사 충전물은 기존 충전물에 비하여 더 높은 물질전달속도를 보였고, 본 검증용액 물성에 대해서는 60mesh 가 더 유리하고 큰 개공의 것이 불리하였다.

To investigate the characteristics of screen-packing for industrial application, measurements of absorption rates of carbon dioxide into potassium carbonate-bicarbonate buffer solution containing sodium hypochlorite as a catalyst in the screen packing column were carried out. The mass transfer coefficient and gas-liquid interfacial area of the screen packings were obtained, and also the pressure drop and liquid hold-up in the screen packing column were measured. In consideration of physical properties of the solution, 50 and 60 mesh spherical packings were used. It was found that the spherical screen packing showed the higher mass transfer rate than the ordinary commercial packings, and that the 60mesh spherical packings was better than 50mesh packings for the absorption.
