SYSTEMS AND METHODS FOR GAS DISPOSAL
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.
