Process for enriching a liquid with a gas and enriched product

A method of making a liquid enriched with a high concentration of dissolved gas, comprising:

• a. providing a closed reservoir container with a quantity of liquid to a pre-selected level;
• b. providing a quantity of pressurized gas to the closed reservoir container to establish a pre-selected pressure within the container;
• c. enriching the liquid in the closed reservoir container with the pressurized gas using a mixing device, to form a gas-enriched liquid having gas molecules physically bonded to the liquid;
• and
• d. expanding the gas-enriched liquid in a lower pressure system comprising a series of pressure reduction vessels, such that the pressure in the series of pressure reduction vessels is initially equal to that of the closed reservoir and is subsequently reduced in slow incremental fashion, thereby forming a liquid enriched with a high concentration of dissolved gas;
• wherein the method further comprises transporting the gas-enriched liquid from a first pressure reduction vessel into another pressure reduction vessel in the series, maintaining the same pressure in the respective pressure vessels during transport;
• wherein the initial pressure in the first one of the pressure reduction vessels in the series is created by the flow of an overpressure of gas from the closed reservoir container into the first pressure reduction vessel;
• and
• wherein the flow of an overpressure of gas into the first one of the pressure reduction vessels in the series is closed off from the closed reservoir container, and the overpressure of gas in the first pressure reduction vessel is subsequently directed through an outlet to a next pressure reduction vessel in the series.
