GAS HOLDUP AND PRESSURE DROP IN A MULTISTAGE VIBRATING DISK COLUMN WITH COCURRENT GAS-LIOUID FLOW

[摘要] References(6)Cited-By(18)The gas holdup and pressure drop of a multistage vibrating disk column with cocurrent gas-liquid flow are measured and the effects of column geometry and operating variables are determined for the evaluation of column performance. Among the operating variables, the vibrating speed of the disks Av (amplitude A multipled by vibrating frequency v) has a definite effect on the gas holdup and pressure drop at speeds higher than a certain critical speed Avr. At speeds lower than Avc, disk vibration has little effect on gas holdup and pressure drop. The gas holdup and pressure drop are correlated successfully by the addition of increased values due to disk vibration to those in the absence of vibration.
