Supercritical Water Oxidation to Treat Biomass and Organic Waste to Produce Chemical Products and Sodium Formate

A method for Sodium Formate production, comprising:

• producing steam, utilizing a small modular nuclear reactor power plant system;
• producing first Carbon Dioxide via supercritical water oxidation using a supercritical water oxidation reactor;
• receiving the first Carbon Dioxide into a solid oxide electrolysis cell;
• producing a Carbon Dioxide and Carbon Monoxide gas mixture via the solid oxide electrolysis cell;
• producing Carbon Monoxide from the Carbon Dioxide and Carbon Monoxide gas mixture via a pressure swing adsorption process;
• producing second Carbon Dioxide from the Carbon Dioxide and Carbon Monoxide gas mixture via a pressure swing adsorption process;
• producing a Sodium Hydroxide solution via a chlor-alkali membrane process;
• converting the Sodium Hydroxide solution, via a Sodium Hydroxide dehydration process, to a Sodium Hydroxide solid;
• receiving the Sodium Hydroxide solid into a reaction chamber, the reaction chamber receiving a portion of the steam;
• receiving the Carbon Monoxide into the reaction chamber;
• converting the Sodium Hydroxide solid and the Carbon Monoxide into a Sodium Formate solution;
• receiving the Sodium Formate solution into a dehydrator;
• and
• dehydrating the Sodium Formate solution into a Sodium Formate solid.
