       FIELD OF THE INVENTION 
       [0005]    One or more embodiments of the invention generally relate to fluids systems. More particularly, the invention relates to a system for removing entrained gas from a liquid. 
       BACKGROUND OF THE INVENTION 
       [0006]    The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon. 
         [0007]    Degas valves are utilized to remove gas from a liquid/gas dissolved mixture in a pressurized vessel or pipe that requires venting to atmosphere. One specific example of a dissolved gas in a liquid is water treatment utilizing ozone gas in a pressurized contact tank, vessel, or pipe. The reaction between the ozone gas and liquid being treated with ozone gas takes place in the contact tank, vessel, or pipe. The contact tank, vessel or pipe must be vented to prevent over pressurization and it also aids in the removal of bubbles in the liquid. The degas valve is typically mounted directly on top of the contact tank, vessel, or pipe. By moving the degas valve to the floor a height limiting factor affecting the contact tank, vessel, or pipe is eliminated. Other methods of degassing involve heating, vacuum, and sonication. 
         [0008]    In view of the foregoing, it is clear that these traditional techniques are not perfect and leave room for more optimal approaches.

         [0029]    It is to be understood that any exact measurements/dimensions or particular construction materials indicated herein are solely provided as examples of suitable configurations and are not intended to be limiting in any way. Depending on the needs of the particular application, those skilled in the art will readily recognize, in light of the following teachings, a multiplicity of suitable alternative implementation details. 
         [0030]    A preferred embodiment of the present invention and at least one variation thereof provide a method for removing entrained gas from a liquid with a floor-mounted degas valve. Many preferred embodiments are implemented for removing entrained gas from a vessel or a pipe when the degassing device is mounted below the elevation of the vessel or the pipe. Many preferred embodiments comprise a pump, a venturi, a degas valve, and a small vessel. 
         [0031]    An object of many preferred embodiments is to enable the degas valve to be installed away from the vessel or the pipe that it is degassing. Another object of many preferred embodiments is to allow for the degassing of tall vessels or pipelines where the maintenance of the degas valves may otherwise be difficult or dangerous. Yet another object of many preferred embodiments is to provide a system for removing entrained gas from a liquid that reduces the overall height of a vessel that needs to be degassed by allowing the degas valve to be mounted on or near the floor. This may be useful when the degas vessel is being used for both solubilizing a gas and acting as a contact vessel as it enables the full available height of the vessel to be used, and thus more volume may be added to the vessel. 
         [0032]      FIGS. 1A and 1B  illustrate an exemplary degassing system, in accordance with an embodiment of the present invention.  FIG. 1A  is a schematic view of the system, and  FIG. 1B  is a diagrammatic front view of a portion of the system. In the present embodiment, the degassing system comprises a pump  104 , a venturi  105 , a degas valve  101 , and a small vessel  102 . The system is typically used to remove entrained gas from a liquid within a vessel  103 . Degas valve  101  is installed in order to operate while located below the top level of vessel  103 . Referring to  FIG. 1B , degas valve  101  is shown mounted to the top of small vessel  102 , which is mounted on the floor. Referring to  FIG. 1A , pump  104  provides the motive force for venturi  105  to create a low pressure in small vessel  102  and initiate gas/liquid flow from the top of vessel  103  to small vessel  102 . Pump  104  is used in conjunction with venturi  105 ; however, in alternate embodiments the pump may be used by itself to provide the motive force, as shown by way of example in  FIGS. 3 and 4 . The selection of pump  104  is often a function of the chemical properties of the gas/liquid mixture. Since venturi  105  is included, without limitation, in the present embodiment, the design of venturi  105  is also typically considered when choosing the design of pump  104 . Those skilled in the art, in light of the present teachings, will readily recognize that a multiplicity of suitable pumps may be used in various embodiments of the present invention. For example, without limitation, the pump can be a centrifugal pump or a derivative of a centrifugal pump such as, but not limited to, pumps that are separately or closed coupled, pumps with open impellers or closed impellers, turbine pumps, etc. The pump may also be a positive displacement pump or a derivative of such including, without limitation, piston pumps, diaphragm pumps, peristaltic pumps, lobe pumps, gear pumps, screw pumps, progressive cavity pumps, etc. The pump may also be comprised of multiple components such as, but not limited to, a mechanical means for the pumping action and a separate means for powering the mechanical means. The powering means may be, but not limited to, an electric motor or other motive source coupled to the mechanical means with, but not limited to, a shaft, gears, pulleys, hydraulics, or combinations thereof, etc. Additionally, the powering means may be, but not limited to, configured to operate at a constant power level, may be configured to operate a various power levels, or may configured to operate at varying power levels under control from a digital or analog control system. Furthermore, a multiplicity of suitable materials may be used for the construction of the pump such as, but not limited to, various different metals or plastics depending on various factors including, but not limited to, how corrosive the gas/liquid mixture is, the flow rate of the system, the system operating pressure, etc. 
         [0033]    In the present embodiment, venturi  105  creates a lower pressure in small vessel  102  than in vessel  103  being degassed. This pressure differential induces gas/liquid flow from the top of vessel  103 . Venturi  105  may be a standard commercial or custom made venturi to be utilized in conjunction with pump  104  to provide the motive force to cause the gas/liquid mixture from the top of vessel  103  to small vessel  102 . Those skilled in the art, in light of the present teachings, will readily recognize that venturis of various different shapes, sizes and configurations may be used in many embodiments of the present invention. The selection of the venturi is typically a function of the chemical properties of the gas/liquid mixture. Also, the pressure drop/flow across the venturi generally dictates the amount of vacuum developed at a vacuum port of the venturi, and the amount of gas/liquid mixture to be removed from vessel  103  typically determines the amount of vacuum needed at the throat of the venturi, and the amount of vacuum needed at the throat typically determines the size of the venturi. Furthermore, various different materials may be used for the construction of the venturi deepening on factors such as, but not limited to, the chemical properties of the gas/liquid mixture and the system operating pressure. Corrosive mixtures typically require materials such as, but not limited to, stainless steel or chemically compatible plastics. For non-corrosive mixtures the choices of materials are broader including, but not limited to, brass, bronze, cast iron, mild steel, plastics, etc. Systems with higher operating pressures may require the use of metals or reinforced plastics, and unreinforced plastics may be used for systems with lower operating pressures. 
         [0034]    In the present embodiment, degas valve  101  is mounted near the floor and is utilized to relieve and vent the gas portion of the gas/liquid mixture while generally preventing the liquid within small vessel  102  from being vented to the atmosphere. Degas valves are commercially available devices of various sizes and materials. The selection of degas valve  101  is typically a function of the chemical properties of the gas/liquid mixture, if the degas valve is to continuously or occasionally vent gas and the pressure of the gas/liquid mixture. Commercial degas valves usually rely on float actuated valves to separate the gas from the liquid stream and are sensitive to the specific gravity of the liquid and the formation of foam, both of which can affect the operation of the degas valve. Custom degas valves may be used in some embodiments. Some embodiments may comprise custom degas valves under automated control that monitors, parameters such as, but not limited to, gas levels, pressures, specific gravity, etc. 
         [0035]    The size and shape of small vessel  102  is typically a function of the amount of gas/liquid mixture to be degassed, if the degassing is continuous or sporadic and the pressure of the gas/liquid mixture. Those skilled in the art, in light of the present teachings, will readily recognize that the small vessel in various embodiments can take on many shapes such as, but not limited to, cylindrical, spherical, cubical, etc. In the present embodiment, small vessel  102  comprises three openings, an inlet, a gas outlet at the top and a liquid outlet at the bottom, which connects to the throat of venturi  105 . In alternate embodiments where multiple vessels or pipes are being degassed, the small vessel can have multiple inlets. In other embodiments the multiple vessels or pipes may be individually selected either manually or under remote control. The selection of the construction material for the small vessel is often a function of the chemical properties of the gas/liquid mixture. Another design parameter that may be considered for the small vessel is the operating pressure of the overall system. This may dictate the method of construction and thickness of the materials to be used for the small vessel. The small vessel design is custom manufactured for each system utilizing off the shelf parts cut and welded together in order to meet the design requirements for each application of the invention. The vessel is constructed with an inlet and outlet on each end, and a discharge at the top for attachment of the degas valve. 
         [0036]    In typical use of the present embodiment, the operation of degas valve  101  is based on the motive force provided by the combination of pump  104  and venturi  105 . Pump  104  circulates liquid from vessel  103  through venturi  105 . Venturi  105  creates a vacuum at its vacuum throat, which is connected to small vessel  102 . This creates a pressure differential between small vessel  102  and vessel  103  to be degassed and induces a flow of the gas/liquid mixture that accumulates at the top of vessel  103  through a conveyance  106  such as, but not limited to, a pipe or tube into small vessel  102 . In small vessel  102  the gas in the gas/liquid mixture separates from the liquid. The gas being lighter rises and is vented through degas valve  101  and the liquid being heavier sinks to the bottom of small vessel  102 . The liquid leaves small vessel  102  through a conveyance  107  such as, but not limited to, a pipe or tube, and due to the lower pressure created at the throat of venturi  105  the liquid flow is induced into venturi  105 . Once the liquid enters venturi  105 , it mixes with the liquid circulating from vessel  103  by circulating pump  104  through conveyances  108  and  109  and this liquid returns to vessel  103  through a conveyance  110  to mix with the fluid in vessel  103 . 
         [0037]    Referring again to  FIG. 1B , the overall height of vessel  103  to be degassed can be reduced with the use of floor mounted degas valve  101 . Mounting small vessel  102  and degas valve  101  to the floor also enables vessel  103  to make use of the full available height within the confines of the particular system. The present embodiment can also be employed in a design application of an integrated system of limited height with a vessel needing to be degassed that would not allow the degas valve to be mounted on top of this vessel. 
         [0038]      FIG. 2  illustrates an exemplary degassing system, in accordance with an embodiment of the present invention. In the present embodiment, a degas valve  201  is installed in order to operate while located below the top level of a pipe  203 . The system comprises degas valve  201 , a small vessel  202 , a pump  204 , and a venturi  205 . The system is typically used to remove entrained gas from a liquid within pipe  203  and functions similarly to the embodiment shown by way of example in  FIG. 1 . Pump  204  provides the motive force for venturi  205  to create a low pressure in small vessel  202  and initiate gas/liquid flow from a high spot in pipe  203  through a conveyance  206  into small vessel  202  where the gas/liquid mixture is degassed. The gas is released through degas valve  201 , and the liquid flows into venturi  205  through a conveyance  207 . The liquid from small vessel  202  then combines with the flow of liquid being circulated from pipe  203  by pump  204  through conveyances  208  and  209  in venturi  205  and returns to pipe  203  through a conveyance  210  to mix with the liquid in pipe  203 . 
         [0039]      FIG. 3  illustrates an exemplary degassing system, in accordance with an embodiment of the present invention. In the present embodiment, the degassing system comprises a degas valve  301 , a small vessel  202  and a pump  304 . The system is typically used to remove entrained gas from a liquid within a vessel  303 . Degas valve  301  is installed in order to operate while being below the top level of vessel  303 . Pump  304  provides the motive force to create a low pressure in small vessel  302  and initiate gas/liquid flow from the top of vessel  303 . Since no venturi is used, the design of pump  304  is typically driven by the amount of motive force required to move the gas/liquid mixture from vessel  303 , and the type of pump chosen, for example, without limitation, centrifugal or positive displacement, is typically driven by the same requirement and the need to prime the system. A positive displacement pump is generally a good choice for pump  304 , when the system does not utilize a venturi to provide the motive force for the gas/liquid mixture, as, during start up, a centrifugal pump may be subject to cavitations if the system is not properly primed. 
         [0040]    In typical use of the present embodiment, the system operates similarly to the embodiment shown by way of example in  FIG. 1 ; however, since no venturi is used, the fluid flow is induced into the inlet of pump  304  by the low pressure at this inlet, and the liquid is directly returned to vessel  303  from pump  304 . By generating a low pressure within small vessel  302 , pump  304  creates a pressure differential that induces the flow of the gas/liquid mixture from the top of vessel  303  through a conveyance  306  such as, but not limited to, a pipe or tube that is connected to small vessel  302 . At small vessel  302  the gas separates from the liquid and is vented out degas valve  301 , and the liquid exits the bottom of small vessel  302  back to pump  304  through a conveyance  307 . Pump  304  returns the liquid to pipe  303  through a conveyance  310 . 
         [0041]      FIG. 4  illustrates an exemplary degassing system, in accordance with an embodiment of the present invention. In the present embodiment, the degassing system comprises a degas valve  401 , a small vessel  402  and a pump  404 . The system is typically used to remove entrained gas from a liquid within a pipe  403  with degas valve  401  installed below the top level of pipe  403 . Pump  404  provides the motive force to create a low pressure in small vessel  402  and initiate gas/liquid flow from a high spot in pipe  403 . In typical use of the present embodiment, the system operates similarly to the embodiment shown by way of example in  FIG. 3 . By generating a low pressure within small vessel  402 , pump  404  creates a pressure differential that induces the flow of the gas/liquid mixture from a high spot in pipe  403  through a conveyance  406  such as, but not limited to, a pipe or tube that is connected to small vessel  402 . At small vessel  402  the gas separates from the liquid and is vented out degas valve  401 , and the liquid exits the bottom of small vessel  402  back to pump  404  through a conveyance  407 . Pump  404  returns the liquid to pipe  403  through a conveyance  410 . 
         [0042]    Those skilled in the art, in light of the present teachings, will readily recognize that degassing systems in alternate embodiments may be implemented in a multiplicity of suitable arrangements. For example, without limitation, some alternate embodiments may comprise additional components such as, but not limited to, additional pumps, venturi injectors, small vessels, degas valves, vessels, etc. Some alternate embodiments may have the components in various different configurations. For example, without limitation, the conveyances may be connected to the components in various different locations or the degas valve and small vessel may be located in various different locations such as, but not limited to, on the floor, on the side of the vessel or pipe to be degassed, on various different components in the system, etc. In one alternate embodiment, the pump circulates water from the small vessel to the vessel or pipe to be degassed. The pump inlet creates a low pressure at its inlet, which is connected to the small vessel. This creates a pressure differential between the small vessel and the vessel or pipe to be degassed and induces a flow of gas/liquid mixture that accumulates at the high spot in the vessel or pipe into the small vessel. In the small vessel, the gas/liquid mixture separates; the gas being lighter rises and is vented through the degas valve, and the liquid being heavier sinks to the bottom of the small vessel. The pressure differential between the small vessel and the pump, which is low at the inlet of the pump and higher in the small vessel, induces the liquid to flow into the pump. The liquid from the small vessel is then sent to the vessel or pipe by the pump to mix with the fluid in the vessel or pipe. 
         [0043]    In another alternate embodiment, the entire system is fabricated on a single base, with only two connection points on the system, plus the electric power for the pump. The inlet of the system is connected to the outlet at the top of the vessel or pipe to be degassed. The inlet of the system is where the gas/liquid mixture leaves the vessel or pipe to be degassed, and the outlet is where the degassed liquid is returned to the vessel or pipe. This single base system may be used with a venturi or without a venturi. The single base system may be configured to mount on a floor, attach to a side of the vessel or pipe, hang from the pipe, or any placed in any other available space. 
         [0044]    In various other alternate embodiments manual control systems, automatic control systems, or combinations thereof may be utilized. Various analog or digital sensors such as, but not limited to, pressure sensors, vacuum sensors, flow sensors, gas sensors, temperature sensors, etc. may be used to monitor and or provide inputs to control systems. Some embodiments may further comprise controllable flow valves or pressure release valves. In some embodiments the operations of the pump may be controlled dependant on readings from various sensors. Other embodiments may also comprise alarm or warning systems to indicate operating parameters outside of safe limits. Still other embodiments may also comprise automated shutdown controls to prevent damage or dangerous situations. 
         [0045]    All the features disclosed in this specification, including any accompanying abstract and drawings, may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features. 
         [0046]    Having fully described at least one embodiment of the present invention, other equivalent or alternative methods of providing a degassing system according to the present invention will be apparent to those skilled in the art. The invention has been described above by way of illustration, and the specific embodiments disclosed are not intended to limit the invention to the particular forms disclosed. For example, the particular implementation of the system may vary depending upon the particular type of fluid mixture being degassed. The systems described in the foregoing were directed to gas/liquid implementations; however, similar techniques are to degas various different types of fluid mixtures such as, but not limited to, mixtures of gas and viscous liquids, gas/sludge mixtures, gas/particle mixtures, mixtures of multiple gasses, etc. Implementations of the present invention for use with various different types of mixtures are contemplated as within the scope of the present invention. The invention is thus to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the following claims.
