A treatment process for remediating contaminants in a mixture of contaminated fluids, including at least one liquid fluid and at least one gaseous fluid, includes the steps of: preparing a liquid treatment composition containing at least 80 volume % of an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 weight percent, and at least one of fulvic acid and humic acid at a collective concentration of 0.1-5 wt % of the treatment composition; adding a dosage of the treatment composition to a mixture of contaminated fluids including a liquid portion and a gaseous portion; and allowing the treatment composition to react with the mixture of contaminated fluids for at least 10 minutes, wherein a pH of the treatment composition is at least 13.0 and the aqueous solution contains at least one of NaOH and KOH.

A carbon capture system is used to remove carbon dioxide from flue gas emissions. The system consists of a first scrubbing column, a carbonating tower, and a separation system. In the first scrubbing column, nitrates and sulfates are removed from the flue gas, producing a purified flue gas and a bottoms product containing the sulfates and nitrates. The purified flue gas is then transferred to a carbonating tower, where it is contacted with a solution (such as brine, ammonia, or a weak base) to remove carbon dioxide, producing a lean brine solution. The lean brine solution is then filtered to recover sodium bicarbonate or soda ash.
