Claim:
1. A sodium carbonate-producing system, comprising: (a) an electrical cell electrolysis reactor comprising a cathode chamber and an anode chamber separated by a membrane, a sodium chloride solution inlet connected to the anode chamber, a water inlet connected to the cathode chamber, an outlet connected to the anode chamber that collects gas comprising chlorine from the anode chamber, and an outlet connected to the cathode chamber that collects an aqueous solution comprising sodium hydroxide from the cathode chamber; (b) a reactor comprising an inlet that receives aqueous solution collected from the cathode chamber in (a), an inlet that receives gas comprising chlorine collected from the anode chamber in (a), and an outlet that delivers sodium hypochlorite; and (c) a carbonation reactor comprising an inlet that receives aqueous solution collected from the cathode chamber in (a), an inlet that receives sodium hypochlorite produced in (b), an inlet that receives a gas comprising carbon dioxide, and an outlet that delivers sodium carbonate.
