Recovery of [CO2]T from seawater/aqueous bicarbonate systems using a multi-layer gas permeable membrane

The present invention is generally directed to a system for recovering CO2 from seawater or aqueous bicarbonate solutions using a gas permeable membrane with multiple layers. At elevated pressures, gaseous CO2 and bound CO2 in the ionic form of bicarbonate and carbonate diffuse from the seawater or...

Beschreibung
Zusammenfassung:	The present invention is generally directed to a system for recovering CO2 from seawater or aqueous bicarbonate solutions using a gas permeable membrane with multiple layers. At elevated pressures, gaseous CO2 and bound CO2 in the ionic form of bicarbonate and carbonate diffuse from the seawater or bicarbonate solution through the multiple layers of the membrane. Also disclosed is the related method of recovering CO2 from seawater or aqueous bicarbonate solutions.
