Abstract
Systems and methods of capturing and sequestering carbon dioxide, comprising mixing a substantially non-aqueous solvent and an alkali such that the solvent and alkali form a solvent suspension, mixing water and a flue gas containing carbon dioxide with the solvent suspension such that a reaction occurs, the reaction resulting in the formation of a carbonate, water and heat.
Claims11
A carbon capture and sequestration system comprising:
- a carbon capture assembly comprising a mixing vessel in which an alkali is mixed with a substantially non-aqueous solvent to form a suspension and at least one reaction vessel, the reaction vessel fluidly connected to the mixing vessel such that the reaction vessel receives the suspension of alkali and solvent from the mixing vessel through a first input, receives flue gas containing carbon dioxide through a second input and receives water through a third input such that carbonic acid, carbonate, water and heat are formed in the reaction vessel;
- and
- a solvent regeneration assembly fluidly connected to the reaction vessel, the solvent regeneration assembly comprising at least one heat exchanger, a cryogenic drying vessel fluidly connected to the heat exchanger, and a hot distillation vessel fluidly connected to the cryogenic drying vessel.
