Abstract
An improved bubble tray for use in a vertically or horizontally oriented absorber, contactor or fractionation vessel for intimately contacting a gas with a liquid, the gas traveling upwardly in the vessel while the liquid flows downwardly, including a horizontal tray dividing the vessel into an upper and lower zone, the tray having a plurality of spaced apart openings, a vertical tube for each opening, the lower end of each tube being secured to the horizontal tray, a horizontal washer received on each of the tubes at a location spaced below the tube upper end and above the horizontal tray and an inverted cup for each of the tubes, each cup having a closed upper portion and a open lower end that is affixed to a washer so that a tube upper end extends within each inverted cup. Each inverted cup has spaced apart elongated vertical openings therein that cause the formation of very small gas bubbles that percolate upwardly through the downwardly flowing liquid.
