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.
