Abstract
An electric power generating system includes an autoclave coupled to a natural gas source, an oxygen source, and having a pressure reducing outlet valve. A high-pressure pump provides a solution of ammonium hydroxide and ammonium carbonate solution under pressure to the autoclave. An exothermic reaction generates high-pressure steam for electrical power generation. A crystallizer receives ammonium carbonate from the reaction for the formation of crystallized ammonium carbonate fertilizer.
Claims21
An electric power generation system comprising:
- an autoclave coupled to a natural gas source, an oxygen source, and having a pressure reducing outlet valve;
- a high-pressure pump coupled to the autoclave for providing a solution of ammonium hydroxide and ammonium carbonate solution under pressure to the autoclave thereby creating an exothermic reaction forming an ammonium carbonate solution;
- a heat exchanger coupled to the autoclave for generating high-pressure steam from heat created by the exothermic reaction;
- and
- an electrical power generator coupled to the heat exchanger for receiving the high-pressure steam to generate electrical power.
