Abstract

See full text

A process is proposed that captures, separates, and enriches carbon dioxide for sequestration after removal from water in equilibrium with air. The proposed process recognizes that carbon dioxide is more soluble in water than other atmospheric gases in air resulting in the proportion of carbon dioxide adsorbed in water from the atmosphere (relative to the other atmospheric gases) being higher than the proportion of carbon dioxide naturally occurring in air. To capitalize on this “convenient truth,” the proposed process aerates (dissolves) in water carbon dioxide gas with other atmospheric gases originating from air in an aerator (aeration) according to Henry's gas law of solubility and then deaerates (strips) these dissolved atmospheric gases from the water in a deaerator (deaeration). The process of aeration and deaeration of these atmospheric gases is repeated multiple times in series until the separated and enriched carbon dioxide gas concentration purity is sufficient for sequestration.
