Abstract
Aspects of the invention include methods of contacting carbon dioxide with an aqueous mixture. In practicing methods according to certain embodiments, a subterranean brine may be contacted with carbon dioxide to produce a reaction product, which may or may not be further processed as desired. Also provided are methods in which a brine or minerals are contacted with an aqueous composition. Aspects of the invention further include compositions produced by methods of the invention as well as systems for practicing methods of the invention.
Claims40
A method comprising:
- contacting CO2 with a subterranean brine to produce a first reaction product comprising carbonic acid, bicarbonate, or carbonate or mixture thereof;
- and
- at least one of:
- i. placing the reaction product in an subterranean location;
- or
- ii. producing a solid material from the reaction product.
A method comprising:
- contacting CO2 with an aqueous mixture to produce a first reaction product comprising carbonic acid, bicarbonate, or carbonate or mixture thereof;
- contacting the first reaction product with a subterranean brine to produce a second reaction product;
- and at least one of:
- i. placing the second reaction product in an underground location;
- or
- ii. producing a solid material from the second reaction product.
A system comprising:
- a) a first source of a subterranean brine;
- b) a source of CO2;
- and
- c) a reactor wherein the reactor is operably connected to the source of brine and the source of CO2, and wherein the reactor is configured for contacting the brine with CO2 to produce a reaction product comprising carbonic acid, carbonate, or bicarbonate, or a combination thereof,
- wherein the system comprises at least one of:
- i. a first conduit for placing the reaction product in a first subterranean location
- ii. a conduit for producing a carbonate-containing solid material from the reaction product.
A carbonate-containing solid material comprising carbon wherein the carbon has a δ13C of −10‰ or less and at least one rare earth element.
