Abstract
Abstract The concentration of gas in a liquid is diluted to prevent effervescence and loss of dissolved gas, by introducing a diluent to a liquid emerging from a plug flow chamber within which the liquid is supersaturated with gas by recirculation of the liquid through a closed loop including the plug flow chamber and a gas transfer device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
In combination with the transfer of a relatively compressible fluid to a relatively incompressible fluent material by intermittent recirculation thereof between a transfer device and a collecting zone during which the fluent material is maintained pressurized at a relatively high level, followed by displacement of the fluent material with the compressible fluid absorbed therein from the collecting zone under a relatively low level pressure; the method of minimizing effervescence of the compressible fluid resulting from outflow of the fluent material from the collecting zone, including the steps of: supersaturating the fluent material with said compressible fluid during said recirculation; and supplying a liquid diluent to the fluent material after supersaturation thereof with the compressible fluid.
Claim 2
Dependent Claim
115 words
In combination with the transfer of a relatively compressible fluid to a relatively incompressible fluent material by intermittent recirculation thereof between a transfer device and a collecting zone during which the fluent material is maintained pressurized at a relatively high level, followed by displacement of the fluent material with the compressible fluid absorbed therein from the collecting zone under a relatively low level pressure; the method of minimizing effervescence of the compressible fluid resulting from outflow of the fluent material from the collecting zone, including the steps of: supersaturating the fluent material with said compressible fluid during said recirculation; and supplying a liquid diluent to the fluent material after supersaturation thereof with the compressible fluid.
Claim 3
Dependent Claim
38 words
The method of claim 1 wherein said diluent is the fluent material with a low concentration of the compressible fluid dissolved therein as compared to a higher concentration of the compressible fluid dissolved in the supersaturated fluent material.
Claim 4
Dependent Claim
23 words
The method of claim 2 wherein said step of supplying the diluent includes introducing the diluent into the collecting zone during outflow therefrom.
Claim 5
Dependent Claim
40 words
The method of claim 3 wherein the diluent is introduced into the collecting zone only when the pressure therein is reduced below said relatively high level during said displacement of the fluent material therefrom under the relatively low level pressure.
Claim 6
Dependent Claim
23 words
The method of claim 1 wherein said step of supplying the diluent includes introducing the diluent into the collecting zone during outflow therefrom.
Claim 7
Dependent Claim
40 words
The method of claim 5 wherein the diluent is introduced into the collecting zone only when the pressure therein is reduced below said relatively high level during said displacement of the fluent material therefrom under the relatively low level pressure.
Claim 8
Dependent Claim
144 words
In a method of transferring a relatively compressible fluid to a relatively incompressible fluent material, the steps of: inducing a continuous flow of the fluent material through a transfer device under a relatively high pressure; directing said flow for recirculation of the fluent material through a closed loop between the transfer device and a collecting zone within which the concentration of the compressible fluid within the fluent material increases; intermittently displacing the fluent material from the collecting zone under a relatively low pressure when the concentration of the compressible fluid therein has increased to a predetermined value, and rapidly diluting the concentration of the compressible fluid in the fluent material at said predetermined value with a liquid diluent to prevent effervescence in response to displacement of the fluent material from the collecting zone by a reduction in pressure thereof from said relatively high pressure.
Claim 9
Dependent Claim
144 words
In a method of transferring a relatively compressible fluid to a relatively incompressible fluent material, the steps of: inducing a continuous flow of the fluent material through a transfer device under a relatively high pressure; directing said flow for recirculation of the fluent material through a closed loop between the transfer device and a collecting zone within which the concentration of the compressible fluid within the fluent material increases; intermittently displacing the fluent material from the collecting zone under a relatively low pressure when the concentration of the compressible fluid therein has increased to a predetermined value, and rapidly diluting the concentration of the compressible fluid in the fluent material at said predetermined value with a liquid diluent to prevent effervescence in response to displacement of the fluent material from the collecting zone by a reduction in pressure thereof from said relatively high pressure.
Claim 10
Dependent Claim
25 words
The method of claim 7 wherein said step of diluting includes: introducing said diluent to the collecting zone during said displacement of the fluent material.
