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.
Claims50
A method of assessing a region for suitability of sequestering carbon dioxide comprising;
- a) creating a representation of the region comprising a combination of
- i. physical data wherein the physical data comprises data indicative of the presence or absence of sources either of divalent cations or alkalinity and
- ii. anthropogenic data comprising data indicative of the presence or absence of sources of anthropogenic carbon dioxide, and
- b) determining the proximity of the sources either of divalent cations or alkalinity to the sources of anthropogenic carbon dioxide.
A method for determining the probability that a subterranean brine in a region is suitable for at least one of the following processes;
- i. absorption of gaseous carbon dioxide;
- ii. reaction with an aqueous solution comprising dissolved carbon dioxide, carbonic acid, carbonate or bicarbonate or any combination thereof, the method comprising;
- a) determining one or more properties of the subterranean brine, and
- b) contacting the subterranean brine with carbon dioxide and or the aqueous solution.
A method for determining the source of components of a carbon containing reaction product comprising:
- a) creating a first profile of a carbon containing reaction product;
- b) obtaining a second profile of a subterranean brine;
- c) comparing the first profile to the second profile;
- and
- d) determining whether the carbon containing product was made with the brine.
A system comprising:
- a. a source of one or more subterranean brines;
- b. a source of a carbon dioxide;
- c. a detector configured for determining the composition of the one or more subterranean brines;
- and
- d. a reactor for adjusting the composition of the one or more subterranean brines, wherein the reactor is operably connected to the source of one or more subterranean brines and the source of carbon dioxide and wherein the detector is operably connected to the reactor.
