In accordance with at least one aspect of this disclosure, a system for dissolving gases into a liquid without side-stream pumping includes a pressure vessel defining a liquid inlet and a liquid outlet, a gas inlet device disposed within an internal chamber of the pressure vessel, a gas source in selective fluid communication with the gas inlet device and the internal chamber of the pressure vessel through a gas control valve and configured to provide a gas pressure, a liquid inlet pipe in selective fluid communication with the liquid inlet of the pressure vessel through a liquid inlet valve, and an outlet pipe in selective fluid communication with the liquid outlet through a liquid outlet valve for discharging the liquid from the internal chamber of the pressure vessel. The gas pressure both facilitates the dissolving of the gas in the liquid and forces the liquid out of the pressure vessel when the liquid is exposed to the gas pressure.

1. A system for dissolving a gas into a liquid, comprising: a pressure vessel defining an internal chamber configured to hold a liquid and to provide a gas head space above the liquid, the pressure vessel also defining a liquid inlet and a liquid outlet;a liquid inlet pipe in selective fluid communication with the liquid inlet of the pressure vessel through a liquid control valve;a liquid source in selective fluid communication with the liquid inlet pipe of the pressure vessel to supply liquid at atmospheric pressure to the internal chamber;a gas inlet device disposed within the internal chamber of the pressure vessel and configured to allow gas to enter the pressure vessel;a gas source in selective fluid communication with the gas inlet device and the internal chamber of the pressure vessel through a gas control valve to supply a pressurized gas to the pressure vessel to pressurize the internal chamber and dissolve at least a portion of the gas into the liquid; andan outlet pipe in selective fluid communication with the liquid outlet through a liquid outlet valve for discharging pressurized and gasified liquid from the internal chamber of the pressure vessel, wherein gas pressure resulting from the supply of the pressurized gas both facilitates the dissolving of the gas in the liquid and forces the liquid out of the pressure vessel when the liquid is exposed to the gas pressure and the liquid outlet valve is open. 2. The system of claim 1, wherein the gas inlet device is configured to introduce pressurized gas into the liquid. 3. The system of claim 2, wherein the surface area of the gas inlet device is at least half of the surface area of a bottom of the pressure vessel. 4. The system of claim 1, further comprising an energy recovery device, wherein the energy recovery device is associated with at least one of the liquid inlet and the liquid outlet of the pressure vessel. 5. The system of claim 4, wherein the energy recovery device is a micro-turbine. 6. The system of claim 1, wherein the outlet pipe and the inlet pipe are the same pipe and the liquid inlet and the liquid outlet valve are the same valve. 7. The system of claim 1, further comprising a plurality of pressure vessels connected in a series and configured to supply a constant flow output. 8. The system of claim 7, further comprising an energy recovery device connected to at least one of the plurality of pressure vessels. 9. The system of claim 1, further comprising a control system, wherein the control system is configured to: open the liquid inlet valve to allow liquid to flow into the internal chamber until a first predetermined condition occurs;open the gas control valve after closing the liquid inlet valve to pressurize the internal chamber with the gas until a second predetermined condition occurs; andopen the liquid outlet valve to effuse the liquid from the internal chamber. 10. The system of claim 9, wherein the first predetermined condition includes at least one of a time or a fill level of the internal chamber. 11. The system of claim 9, wherein the second predetermined condition includes at least one of a time, a pressure of the internal chamber, a dissolution rate of the gas into the liquid, or a gas content of the liquid. 12. The system of claim 1, further comprising a venturi disposed in fluid communication with the liquid outlet pipe and configured to add the gas from the gas head space to an outlet flow. 13. A system, comprising: a floating vessel including a submerged portion configured to sit below a water level of a body of water; anda pressure vessel disposed within the submerged portion and defining an internal chamber configured to hold a liquid and to provide a gas head space above the liquid, the pressure vessel also defining a liquid inlet and a liquid outlet;a liquid inlet, pipe in selective fluid communication with the liquid inlet of the pressure vessel through a liquid control valve;a liquid source in selective fluid communication with the liquid inlet pipe of the pressure vessel to supply liquid at atmospheric pressure to the internal chamber;a gas inlet device disposed within the internal chamber of the pressure vessel and configured to allow gas to enter the pressure vessel;a gas source in selective fluid communication with the gas inlet device and the internal chamber of the pressure vessel through a gas control valve to supply a pressurized gas to the pressure vessel to pressurize the internal chamber and dissolve at least a portion of the gas into the liquid; andan outlet pipe in selective fluid communication with the liquid outlet through a liquid outlet valve for discharging the pressurized and gasified liquid from the internal chamber of the pressure vessel, wherein gas pressure resulting from the supply of the pressurized gas both facilitates the dissolving of the gas in the liquid and forces the liquid out of the pressure vessel when the liquid is exposed to the gas pressure and the liquid outlet valve is open. 14. The system of claim 13, wherein the gas source is also disposed within the submerged portion of the floating vessel. 15. The system of claim 13, wherein the submerged portion connects the liquid inlet of the pressure vessel to the body of water.
