Abstract: The present invention relates to systems and processes for utilizing produced water and captured carbon dioxide to produce high-value products. The system includes a produced water processing system, a carbon capture system, an electrolyzer, and a conversion chamber. The electrolyzer includes a first chamber, a second chamber, and a semi-permeable membrane and first electrode in the first chamber and a second electrode in the second chamber. The first chamber receives treated saturated produced water. The second chamber is operated at a second operating pressure that is less than the first operating pressure and facilitates the passage of sodium ions across the membrane. A current is applied to the electrodes such that the first electrode functions as an anode and the second electrode functions as a cathode, producing hydrogen gas and sodium hydroxide in the second chamber and chlorine gas in the first chamber. The polarity of the electrodes and the flow of reagents into the first and second chambers and the flow of products out of the first and second chambers may be reversed.

Abstract: The invention is a system and method of reducing, reacting, and/or removing an oxidant or unwanted chemical species from a chemical stream. Particularly, the system and method include the use of one or more reductants that react with the undesired chemical species. The reductant and the chemical stream are added to a reactor and allowed to react for a desired amount of time. The reductant will reduce, react with, and/or remove the chemical species from the stream. The excess reductant and reaction products are then removed from the reactor, as described in more detail herein below.
