Abstract

Method of dissolving a gas in a liquid, of the kind in which a mass of the liquid is subjected to the action of a centrifugal force of rotation, in which said liquid mass flows from a corresponding feed end to the part of said closest mass to the axis of rotation, where the separate admission of the gas and liquid is effected, towards a discharge end corresponding to a part of said liquid mass farther from the axis of rotation than the entrance end, where the gas evacuation is effected. Less dissolved part and the liquid, characterized in that a controlled speed path of said liquid mass is ensured between the feed and discharge ends, on the one hand, developing a back pressure acting on a downstream part of the path of said mass, and on the other hand, feeding by default said mass with a controlled flow of said liquid, so that a pre-food area is formed the liquid is placed between the axis of rotation and said feed end, in which liquid and gas are simultaneously admitted, and where the liquid admitted to the gas to be dissolved is divided, and the liquid divided to said feed end is projected.
