  • Publication number: 20220403321
    Abstract: An algae cultivation medium includes a growth medium and at least one of an amine additive and a water-soluble biomimetic catalyst. A related method of increasing carbon shuttling in an algae cultivation medium includes adding at least one of the amine additive and the water-soluble biomimetic catalyst to the algae cultivation medium.

  • Patent number: 11207634
    Abstract: A method and apparatus are provided for recovering an amine solvent from an acid gas stream. The apparatus includes a water wash recovery column, a nozzle for spraying water wash and an amine nucleation agent into the water wash recovery column and an inlet port for introducing acid gas into the water wash recovery column adjacent the lower end thereof. The method includes the steps of treating the acid gas stream in the water wash recovery column with a counter-current flow of water wash in an amine nucleation agent, discharging treated acid gas from an upper end of the water wash recovery column and collecting water wash, amine nucleation agent and entrained amine solvent from the acid gas stream and a sump at a lower end of the water wash recovery column.

  • Patent number: 10702826
    Abstract: A method of removing and capturing an acid gas from a fluid stream includes exposing the fluid stream to an aqueous scrubbing solution in the presence of a packing element including alternating hydrophobic and hydrophilic features or zones. A related apparatus is also disclosed.

  • Patent number: 10589214
    Abstract: The present invention relates to methods for improving carbon capture by providing particles within an amine solvent. The particles provide for increased turbulence at the interface between the counter-flowing gas and solvent, which allows for increased amine and carbamate salt diffusion between the liquid film and bulk.

  • Patent number: 10322367
    Abstract: The present invention relates to methods for improving carbon capture using entrained catalytic-particles within an amine solvent. The particles are functionalized and appended with a CO2 hydration catalyst to enhance the kinetics of CO2 hydration and improve overall mass transfer of CO2 from an acid gas.

  • Publication number: 20180079660
    Abstract: The present invention relates to a method and system for removing nitrosamines from amine-based carbon capture systems by circulating waterwash through a filter of activated carbon. Nitrosamine emission control strategies are critical for the success of amine-based carbon capture as the technology approaches industrial-scale deployment. Waterwash systems are used to control volatile and aerosol emissions, including nitrosamines, from carbon capture plants, but it is still necessary to remove or destroy nitrosamines in the circulating waterwash to prevent their subsequent emissions into the environment. The circulation of the water over a sorbent bed of activated carbon provides a cost-effective approach to selectively remove nitrosamines from the waterwash effluent to reduce the environmental impact associated with amine-based carbon capture.
