Abstract: A method for removing at least a portion of dissolved gases from a liquid dispersion utilizing a closed, cylindrical tower with an inlet in its upper portion, a tank at the bottom of the tower for collecting liquids, a central pipe in the tower open at each end, the upper end extending above the inlet and the lower end terminating above the level of the collected liquids in the tank and a plurality of inclined surfaces mounted around the central pipe and providing a flow path for the dispersion, each of the plurality of inclined surfaces being shaped and positioned to reverse the direction of flow and dimensioned to form an annular gap between the inclined surfaces and the wall of the tower, the inclined surfaces forming an angle of about 45.degree. to 80.degree. with the central pipe.
