Therefore at reasonable pressures if there is no i th gas in the atmosphere but is in the fluid, that i th gas will be stripped out of the fluid and into the atmosphere in contact with the gas. For example, if methane gas is dissolved in water as is the case where some gas wells are drilled thru an aquifer. Since there is no methane in the injected air, methane should come out of the water until tl-ie partial pressure of the methane in the atmosphere is in equilibrium with the pressure of methane in the water, effectively stripping methane from the water. A phase separation device can be used to get rid of the saturated gas above the water and the process repeated to further reduce the dissolved methene levels. A modification of the in line mixer can be located downstream of the injection mixer.
Any free atmosphere is reinjected into the water stream.
In present applications nitrogen is being stripped from water due to the injection of oxygen. One test indicates that the combination of the two mixers establishes equilibrium between the dissolved gas in the water and the molal concentrations of gas in the atmosphere.
