Patent ID: 8252242

Claim:
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 by one or more valves 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 by one or more valves, the solvent regeneration assembly comprising a serial arrangement including at least one heat exchanger for cooling a mixture of solvent and water from the reaction vessel, the at least one heat exchanger being connected to the reaction vessel, a cryogenic drying vessel for separating a portion of the solvent from the water, the cryogenic drying vessel being fluidly connected to the at least one heat exchanger, and a hot distillation vessel for separating remaining portions of the solvent from the water, the hot distillation vessel being fluidly connected to the cryogenic drying vessel; wherein the separated solvent is recycled to the mixing vessel and the separated water is recycled to the third input of the reaction vessel.
