이중관 기포탑내에서 CMC 수용액중의 기액간 물질전달 = Mass Transfer between Gas and Liquid through CMC Solutions in a Bubble Column with a Draught Tube

다국어 초록 (Multilingual Abstract)

The gas holdup ε_g and volumetric liquid-phase mass transfer coefficient K_La in a bubble column with a draught tube were studied experimentally with variation of the concentration of CMC solutions, gas velocity and diameter and height of the draught tube. The gas holdup ε_g increased with decreasing concentration of CMC solutions and increasing the diameter ratio of the draught tube to column diameter but was not affected by H/H_7. The volumetric liquid-phase mass transfer coefficient K_La decreased with increasing concentration of CMC solutions and the height ratio of the draught tube to column height but was not affected by the diameter ratio of the draught tube to column diameter. Dimensionless equations of the gas holdup ε_g and the volumetric liquid-phase mass transfer coefficient K_La were proposed from the experimental results.
