Method and Device for Dissolving Gas in a Liquid

摘要

This invention relates to a method of dissolving a gas entrained by a liquid under pressure and circulating in a venturi (or other similar device), characterized in that at the outlet of the venturi, the dissolving liquid charged with the gas to be dissolved is conveyed in a duct in which the liquid circulates under turbulent conditions, the said duct discharging at the base of a vertical decanter, from which are extracted a liquid phase saturated in gas on the one hand, and at the top of the decanter, the excess undissolved gas on the other. This gas can be recycled to the venturi. The invention also relates to the device which can be used for implementing the said method. 2 figs. (ERA citation 11:020672)
