  • Systems and methods for removing carbon dioxide from a combustion flue gas and/or air
    Patent number: 12097465
    Abstract: Systems and methods for removing carbon dioxide from a combustion flue gas and/or air by using a high-pressure aqueous ammonia solvent and a plurality of liquid driven ejectors to absorb and remove the carbon dioxide for carbon capture utilization or storage. The aqueous ammonia solvent is regenerated at a high pressure to save potential compression energy required for the absorption and removal of carbon dioxide.

  • Low Energy Ejector Desalination System
    Publication number: 20240270607
    Abstract: Systems and methods for treating a raw wastewater feed stream using a low energy ejector, which works as a heat pump to increase the pressure and temperature of a two-phase distillate stream used, in part, to heat the raw wastewater feed stream. The systems and methods utilize heat from a liquid distillate stream and a concentrated liquid wastewater stream to pre-heat the raw wastewater feed stream and produce a liquid distillate product stream.
