1. A system for effectively reducing pollutants from a gas stream comprising:

  • a first set of mixing equipment adapted to admix a hydroxide with the gas stream to create a first admixture in which carbon dioxide in the gas stream can react with a hydroxide to produce a bicarbonate product or a combination of bicarbonate and carbonate products in a first liquid outflow anda second set of mixing equipment adapted to admix a hypochlorite and the bicarbonate product or the combination of bicarbonate and carbonate products with the gas stream to create a second admixture in which nitrogen-based or sulfur-based acid gases can react with the hypochlorite and the bicarbonate product or the combination of bicarbonate and carbonate products to produce nitrate or sulfate products in a second liquid outflow,wherein the gas stream flows through the second set of mixing equipment before at least a portion of the gas stream flows through the first set of mixing equipment.
