This unit consists of a column of transparent plastic material equipped with two sieve trays and of a bubble cap tray. The upper sieve tray will distribute gas and liquid onto the bubble cap tray installed below. Three pressure taps along the column supply the pressure drops to the bubble cap tray and to the lower sieve tray. The unit also includes a tank for the water, a pump that recycles the water to the column top, and a blower connected with the column bottom. The water flow rate is measured by a variable area flowmeter, whereas the air flow rate is measured by an electronic anemometer. The big diameter of the column (600 mm) enables to observe the operation of the different types of tray easily in the various testing conditions.
