  • Carbon dioxide recovery
    Patent number: 10493397
    Abstract: Carbon dioxide is separated from flue gas by scrubbing the gas with an aqueous solution of ammonia and salt, and the CO2 is therefore released from the solution by heating. The scrubbing step is performed with a co-current stream of an aqueous solution of ammonia and a salt.
    Type: Grant
    Filed: April 30, 2018
    Date of Patent: December 3, 2019
    Inventor: John E. Stauffer
  • Carbon dioxide recovery using an absorption column in combination with osmotic filters
    Patent number: 10293304
    Abstract: A process for the removal of CO2 from flue gases using a co-current flow absorption column followed by one or more serial osmotic filters. The permeate is heated to strip out the CO2. Both sides of the filters are fed back to the column input.

  • Method of producing an electrical potential
    Patent number: 9147912
    Abstract: A method of producing an electrical potential by way of a rechargeable battery with a positive electrode of lead and a negative electrode of highly pure zinc. The electrolyte is an aqueous solution of an alkali metal bisulfate.
