In establishing a relationship between the plate efficiency and point efficiency for perforated plates, splashing of the liquid was considered as an entirely new mechanism for the mixing of the liquid phase in the direction of the flow. Actual splashing measurements were reported and correlated here, under different conditions of flow rates, weir height, kinematic viscosity of the liquid and some aspects of tray geometry.
Plate efficiencies for the desorption of ammonia by air were reported for a perforated plate 36 inches long and 3 inches wide. Concentration gradients across the plate were also measured for the ammonia desorption case and for backward distribution of sodium chloride by splashing. These concentration gradients have been related to the splashing measurements.
