Method and System for Processing a Fluid

A process for treating a feed stream in a manner that results in converting a carbon constituent into a carbonate constituent, the process comprising:

• providing the feed stream to a first treatment step, the feed stream being aqueous and comprising:
• at least one ppm to no more than ten percent (by volume) of a hydrocarbonaceous component, and no more than 50,000 ppm of an impurity comprising a metal, a hard mineral, or combinations thereof;
• providing a first treated stream from the first treatment step to a secondary processing step;
• using electrolysis in the secondary processing step to produce a treated aqueous stream comprising at least one percent to no more than thirty percent (by volume) of a hydroxide constituent.

• at least one ppm to no more than ten percent (by volume) of a hydrocarbonaceous component, and no more than 30,000 ppm of an impurity comprising:
• a metal, a hard mineral, or combinations thereof;
• using electrolysis to react the feed stream via the treatment step to produce a treated aqueous stream consisting of at least one percent to no more than thirty percent (by volume) of a hydroxide constituent;
• providing the treated aqueous stream and an air stream comprising the carbon constituent to a neutralization reactor, wherein the carbon constituent and the hydroxide constituent are reactive to a point whereby at least some of the carbon constituent is converted to the carbonate constituent,
• wherein the feed stream comprises produced water, waste water, brine, and combinations thereof,
• wherein the hydroxide component comprises one of potassium hydroxide, calcium hydroxide, sodium hydroxide, and combinations thereof,
• wherein the air stream comprises atmospheric air consisting of at least 200 ppm to no more than 500 ppm carbon dioxide, and
• wherein the carbonate constituent comprises one of potassium bicarbonate, calcium bicarbonate, sodium bicarbonate, and combinations thereof.
