Abstract
The present invention generally relates to systems and methods for the separation and removal of carbon dioxide from a liquid, for example, seawater. The systems include an extraction system that collects carbon dioxide from the seawater through a medium, and removes carbon dioxide from the medium; the extraction systems comprising a reactor and a membrane. Alternatively, the extraction system includes a reactor, a membrane and a catalyst.
Claims23
An extraction system for separating and removing carbon dioxide from a liquid, the system comprising:
- a reactor;
- and,
- a membrane capable of allowing the liquid to flow back and forth across the membrane until equilibrium is established with an air gap from which the carbon dioxide is removable, separated and sequestered;
- wherein the membrane comprises a membrane material permeable to carbon dioxide and water;
- whereby the system converts bicarbonate ion into dissolved carbon dioxide to replace the carbon dioxide which is removed from the liquid.

- and,
- a catalyst;
- wherein the catalyst comprises a catalytic enzyme which converts bicarbonate ion into dissolved carbon dioxide;
- wherein the membrane comprises a membrane material permeable to carbon dioxide and water and comprising pores with sizes from about 5 angstroms to about 40 angstroms;
- whereby the system converts bicarbonate ion into dissolved carbon dioxide to replace the carbon dioxide which is removed from the liquid.
