Abstract

A method for recovering carbon dioxide from acidified seawater using a membrane contactor and passing seawater with a pH less than or equal to 6 over the outside of a hollow fiber membrane tube while applying vacuum or a hydrogen sweep gas to the inside of the hollow fiber membrane tube, wherein up to 92% of the re-equilibrated [CO2]T is removed from the natural seawater.
