Abstract
A system and method of injecting a gas enriched and/or emulsified first liquid into a second liquid is disclosed. The injection can cause generation of a high density of bubbles having a mean diameter of a selected size. The mean diameter of the bubbles can be selected and varied based on the characteristics of the injection system.
Claims23
A method of treating a receiving volume of a first liquid, comprising:
- saturating a transfer liquid with a gas at a pressure of at least 6 bar in a containment vessel;
- releasing the transfer liquid from the containment vessel;
- passing the released transfer liquid through a tube;
- generating a Reynolds number in the effluent from the tube in a range from about 2,220 to about 100,000;
- and
- generating a population of micro-nanobubbles from the tube with the generated Reynolds number having an average diameter that is about 50 microns or less in the receiving volume of the first liquid.

(canceled)
A method of injecting of gas filled bubbles into a liquid, comprising:
- spraying an aqueous liquid into a vessel pressurized to at least 8 bar with gas to create an gas-enriched first liquid;
- and
- piercing a second liquid with the gas-enriched first liquid as a liquid lance having a density at the distal end of a delivery tube substantially similar to the density of the aqueous liquid.
A system for injection of a gas enriched first liquid as a liquid lance into a second liquid comprising:
- a) an elongated small bore tubing with uniform internal dimensions along a length of the tubing;
- b) a proximal end of the tubing for receiving the gas enriched first liquid at pressure elevated above an ambient pressure;
- and
- c) a distal end of the tubing for delivering the gas enriched first liquid into the second liquid at ambient pressure;
- and
- wherein the length and the internal dimension of the tubing are selected to deliver a selected desired mean size bubbles less than about 50 microns delivered to or formed within the second liquid.
