ABSORPTION IN A ROTATING-DISK GAS-LIQUID CONTACTOR

[摘要] References(3)Cited-By(8)Rates of oxygen absorption into water were studied in a rotating-disk gas-liquid contactor, in which liquid films were formed on the surface of disks rotating around the horizontal axis. When plain disks were used, values of the liquid-phase mass transfer coefficient kL were lower than those predicted from the penetration model. However, with disks made of appropriate wire mesh, kL, values agreed quite well with prediction by the penetration model for the range of gas-liquid contact time from 0.2 to 1.5 seconds.This type of gas-liquid contactor equipped with wire mesh disks seems to be a useful apparatus for studies of liquid-phase mass transfer in gas absorption.
