Abstract (en)

An apparatus for dissolving gas in a downflow of liquid, the apparatus comprising an outer vessel (14) including an upper end having an inlet (20), and a lower end having an outlet (24), the outer vessel defining a flow chamber for conducting the downflow between the inlet and the outlet, a funnel member (38) including a tubular portion which defines at least part of the inlet, and which cooperates with the outer vessel to define a collection well, and a downwardly diverging portion extending downwardly into the flow chamber from the tubular portion, the downwardly diverging portion including an outlet end, and defining a bubble contact chamber, and a mechanism (52) for introducing bubbles of gas into the downflow, the mechanism for introducing including a source of gas under pressure, and a bubble dispersing device (60) connected to the source, and positioned within the flow chamber adjacent the outlet end of the downwardly diverging portion so that the bubbles travel in a countercurrent direction into the bubble contact chamber and toward the inlet, and wherein the bubbles are sized to have a buoyant velocity greater than the downflow velocity of the liquid exiting the outlet end, and wherein the downflow velocity of the liquid in the tubular portion is greater than the buoyant velocity of the bubbles. <IMAGE>
