Abstract

전보에 발표한 충전 기포탑 연구의 일환으로서 본 연구에서는 이미 정하여진 최적치수의 spiral wires로 충전하고 기액 접촉 물질전달계에서의 제 특성인자들을 중심으로 실험하였는바, 물질전달계의 기액계면적, 물질전달계수 및 축방향 혼합계수 등을 측정하여 spiral wires의 충전효과를 규명하였다. 그 결과 충전계의 기액계면적과 물질전달계수는 비충전계보다 각각 2배, 4배 증가하였고, 축방향 혼합계수는 비충전계의 1/2로 감소하였다.
The behavior of the gas-liquid contact was studied in a bubble column packed with spiral wires to increase the contact effects. Carbon dioxide-air mixture was passed into potassium carbonate-bicarbonate buffer solution. Under the optimum condition (D=6 ㎜, P/D=2) of the spiral wire packing, the interfacial area for the packed column became approximately two times of that for the column without spiral wires and the liquid-side mass transfer coefficient for the packed column was approximately four times of that for the unpacked column. The axial mixing coefficient of the packed system decreased to one half of the unpacked system.
