Abstract
An apparatus and method for dispersing a gas in a liquid and for increasing gas pressure of a gas from a supply pressure to a delivery pressure. A first pump pumps the liquid to produce a pressurized liquid stream. The gas is injected into the pressurized liquid stream through for instance, a piping tee. The gas injection produces a pressure drop within the gas and as a result, the first pump pumps the liquid stream so that it has a static pressure no greater than the injection pressure. A second pump pumps the resultant pressurized gas-liquid stream so that an outlet liquid stream is produced with the liquid having a greater head than that of the pressurized liquid stream and the gas having the increased delivery pressure.
