Sustainable plasma nitrophosphate process for production of nitrogen and phosphorous products and for carbon sequestration

A method for producing nitrophosphates and mineralized carbon, the method comprising:

• (a) producing nitric acid in a plasma-nitrogen fixation system;
• (b) contacting the nitric acid produced in step (a) with a phosphate source in an acidulation reactor to produce nitrophosphoric acid;
• and
• (c) combining the nitrophosphoric acid from step (b) with carbon dioxide, water, and ammonia in a third reactor, thereby producing a solution comprising nitrophosphates and mineralized carbon.

A system for production of nitrophosphates and mineralized carbon, the system comprising:

• (a) a plasma-nitrogen-fixation system comprising:
• i. a plasma reactor for producing oxidized nitrogen species;
• and,
• ii. an absorber fluidly coupled to the plasma reactor for producing nitric acid from the oxidized nitrogen species;
• (b) an acidulation reactor fluidly coupled to the absorber for combining the nitric acid produced in the absorber with a phosphate source, ammonia, water, and carbon dioxide, thereby producing nitrophosphates and mineralized carbon;
• the acidulation reactor also fluidly coupled to the plasma-nitrogen-fixation system for recycling NOx gases produced in the plasma reactor and the acidulation reactor.
