Systems and methods for gas disposal

A discharge system, comprising:

• a mixing vessel including a nozzle proximate to a first side of the mixing vessel;
• a feedstock input line defining a feedstock flow path in fluid communication with the mixing vessel;
• a solvent input line in fluid communication with the mixing vessel;
• a discharge output in fluid communication with an outlet of the mixing vessel;
• and
• a feedstock valve on the feedstock input line to control the flow of a feedstock being fed into the mixing vessel to dissolve within a solvent thereby generating an effluent discharge solution having a known gas solubility saturation, wherein the solvent input line is operatively connected to the nozzle to direct the solvent toward a gas pocket generated by the gas entering with the feedstock through the feedstock input line, wherein the solvent input line is split into two lines, wherein a first of the two lines defines a flow path to the mixing vessel through the nozzle, and wherein a second of the two lines defines a flow path to the mixing vessel through an inlet on a second side of the mixing vessel.
