A method for controlling the saturation level of gas in a liquid discharge includes obtaining temperature and pressure measurements of a solvent in a mixing vessel and obtaining a pressure measurement of a source feedstock in a feedstock tank, correlating the temperature and pressure measurements of the solvent to baseline data to generate a theoretical uptake rate for the source feedstock into the solvent and a theoretical flow rate of the source feedstock into the mixing vessel, and determining a required opening setting for a feedstock valve in the feedstock input line in order to achieve a desired liquid displacement in the mixing vessel. The method includes determining an uptake duration and achieving an uptake displacement equivalent to the reverse of the desired liquid displacement. The method includes generating a valve operating control law for how the feedstock valve should function in a cycle.

A discharge system includes a mixing vessel and a feedstock input in fluid communication with the mixing vessel. A solvent input is in fluid communication with the mixing vessel. A discharge output is in fluid communication with an outlet of the mixing vessel to discharge effluent. A method for generating turbulence on a liquid surface within a discharge system includes supplying a mixing vessel with feedstock fluid and solvent fluid to generate a liquid mixture and a gas pocket in the mixing vessel. The method includes supplying an impinging solvent fluid through a nozzle extending from a first end of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture.

A machine and process for providing a gas liquid mixture are described. The process can include providing a pressurized fluid stream that includes a mixture of a gas and a liquid; and subjecting the fluid stream to a series of alternating flow regions that include a plurality of laminar flow regions and turbulent flow regions. The machine can include a pressure vessel that includes, above a mid-line, a gas nozzle adapted for the addition of a gas to an interior volume of the pressure vessel and a liquid atomizer adapted for the addition of a liquid to the interior volume of the pressure vessel; below the mid-line, a fluid outlet positioned above a bottom of the pressure vessel and a clean-out port positioned at or adjacent to the bottom of the pressure vessel; and a means for determining a fluid level within the interior volume of the pressure vessel; and a flow path fluidly connected to the fluid outlet, the flow path including a plurality of alternating flow characteristic regions. Further described is the production and storage of the gas liquid mixture.
