A new gas-liquid contacting device has been developed, having a movable perforated plate located upon a fixed perforated plate to improve the efficiencies in gas-liquid contacting. The state of the movable plate, the pressure drop across the tray, liquid hold-up on the plates and the fractional gas hold-up are investigated, providing a basis of operation and design for the new plate column. The movable plate operates differently depending upon gas velocity, and its state is classified into three typical regions : the stationary, floating, and well-floating regions. The pressure drop and the liquid hold-up are correlated, considering the behavior of the movable plate in each region, and equations are developed which predict the transitional gas velocities between regions. No appreciable effect of the movable plate on gas hold-up is found, and it is found that the correlation for gas hold-up on the ordinary tray can be applied to the plate column in this work.
