  • Patent number: 11905172
    Abstract: A novel concept for a high energy and material efficient nitric acid production process and system is provided, wherein the nitric acid production process and system, particularly integrated with an ammonia production process and system, is configured to recover a high amount of energy out of the ammonia that it is consuming, particularly in the form of electricity, while maintaining a high nitric acid recovery in the conversion of ammonia to nitric acid. The energy recovery and electricity generation process comprises pressurizing a liquid gas, such as air, oxygen and/or N2, subsequently evaporating and heating the pressurized liquid gas, particularly using low grade waste heat generated in the production of nitric acid and/or ammonia, and subsequently expanding the evaporated pressurized liquid gas over a turbine. In particular, the generated electricity is at least partially used to power an electrolyzer to generate the hydrogen needed for the production of ammonia.

  • Patent number: 11906227
    Abstract: An apparatus includes a captured carbon dioxide input. The captured carbon dioxide input is coupled to receive captured carbon dioxide from a direct air capture system. The apparatus uses the captured carbon dioxide as a low global warming refrigerant to provide cooling functionality in automotive, commercial, and industrial applications, or other operations involving low global warming refrigerants. In various embodiments, the apparatus is a refrigeration apparatus or a heat pump apparatus. Low global warming carbon dioxide refrigerant is natural, non-toxic, non-flammable, and abundant when obtained from a direct air capture system. Moreover, carbon dioxide refrigerant has a high heat transfer coefficient and has a global warming potential (GWP) of one. Carbon dioxide refrigerant is a more sustainable and efficient coolant option than common refrigerants, such as R22, R152, R404a, and R1234yf refrigerants.

  • Patent number: 11904273
    Abstract: A method for capturing carbon from a source of volatile pollutants includes the steps of capturing a mixture of volatile pollutants and air from the source of volatile pollutants, transporting the volatile pollutant-air mixture to an oxidizer module, converting the volatile pollutants into carbon dioxide within the oxidizer module, transporting the carbon dioxide from the oxidizer module to a contactor, loading the carbon dioxide onto sorbents within the contactor, and separating the carbon dioxide from the loaded sorbents to produce a concentrated carbon dioxide product stream. The step of separating the carbon dioxide from the loaded sorbents may optionally include the steps of passing the loaded sorbents to the oxidizer module, and then heating the loaded sorbents in the oxidizer module with the combustion of the mixture of volatile pollutants and air within the oxidizer module to produce the concentrated carbon dioxide product stream while regenerating the sorbents.
