Abstract

The invention relates to an apparatus and a method for enhancing dissolution of gas in liquid. The apparatus comprises an outer structure and at least one inner structure, at least one gas inlet for injecting gas to a gas space between the outer and inner structures, a wall of the inner structure having holes with the gas arranged to flow through the holes into the inner structure, at least one liquid inlet for feeding liquid into the inner structure to provide a swirl flow arranged to capture gas bubbles of the gas from an inner surface of the wall to form a liquid-gas mixture, and the inner structure designed such that volume of space inside the inner structure increases in the direction of the liquid flow, and at least one outlet for discharging the liquid-gas mixture out from the apparatus. Further, the invention relates to the use of the apparatus.
