Process for dissolving gas into a liquid

A process for dissolving a gas into a liquid, comprising the steps of:

• pressurizing the liquid to a predetermined level;
• selecting a hydrocyclone having an inlet aperture size and configuration and a barrel diameter and length optimized for liquid particle movement through a liquid vortex stream thereof;
• directing the pressurized liquid into the hydrocyclone to form a vortex stream having an evacuated central area;
• injecting the gas into the evacuated area for adsorption into the liquid;
• directing the liquid from the hydrocyclone and into a diffusion column;
• directing the liquid from the diffusion column into a pressure chamber having an upper gas region and a lower liquid region to collect non-adsorbed gas;
• and
• directing the gas within the upper gas region of the pressure chamber back into the evacuated area of the vortex stream.

• pressurizing the liquid to a predetermined level;
• selecting a hydrocyclone having an inlet aperture size and configuration corresponding to the liquid pressure and a barrel diameter and length optimized for liquid particle movement through a liquid vortex stream thereof;
• directing the pressurized liquid into the hydrocyclone to form a vortex stream having an evacuated central area;
• injecting the gas into the evacuated area for adsorption into the liquid;
• directing the liquid from the hydrocyclone and into a diffusion column;

• directing the gas within the upper gas region of the pressure chamber back into the evacuated area of the vortex stream;
• and
• sensing the level of gas within the pressure chamber, and adding pressurized gas into the pressure chamber when the gas level of the pressure chamber falls below a predetermined level.
