A process and system for separating COfrom a flue gas stream is disclosed. The process involves (a) contacting a flue gas stream containing water vapor and COwith an ionic absorbent under absorption conditions to absorb at least a portion of the COfrom the flue gas stream and form a CO-absorbent complex; wherein the ionic absorbent comprises a cation and an anion comprising an amine moiety; and (b) recovering a gaseous product having a reduced COcontent.

Process for the separation of carbon dioxide from flue gas

An aqueous ionic absorbent solution is disclosed containing (a) about 15 wt. % to about 80 wt. % of one or more diluents, based on the total weight of the aqueous ionic absorbent solution; and (b) an ionic absorbent containing a cation and an anion comprising an amine moiety.

Aqueous solutions of amine functionalized ionic compounds for carbon capture processes

Disclosed herein is a method for improving the total energy demand required to separate carbon dioxide (CO) from an aqueous ionic absorbent solution in a post-combustion carbon capture process. The method involves (a) contacting a flue gas stream containing COwith an aqueous ionic absorbent solution under absorption conditions to absorb at least a portion of the COfrom the flue gas stream and form a CO-aqueous ionic absorbent solution stream, wherein the aqueous ionic absorbent solution comprises one or more diluents and an ionic absorbent containing a cation and an anion comprising an amine moiety; and (b) subjecting at least a portion of the CO-aqueous ionic absorbent solution stream to desorption conditions to form a CO-rich stream and an aqueous ionic absorbent solution stream having a reduced COcontent.

One aspect of the present invention relates to amine-functionalized task-specific ionic liquids (TSILs). In certain embodiments, the ionic liquids of the invention comprise beta-hydroxy amines, aryl amines or tertiary amines. The TSILs may be used for gas capture, capitalizing on their non-volatile nature. In certain embodiments, the captured gas is selected from the group consisting of CO, SO, CS, and NO. Another aspect of the present invention relates to a library of CO-philic salts, which library facilitates reactive gas separation. In certain embodiments, the CO-philic salts are CO-reactive TSILs. In certain embodiments, the CO-philic salts are resinous or plastic in nature.

Carbon dioxide scrubbing using ionic materials

One aspect of the present invention relates to ionic liquids comprising a pendant Bronsted-acidic group, e.g., a sulfonic acid group. Another aspect of the present invention relates to the use of an ionic liquid comprising a pendant Bronsted-acidic group to catalyze a Bronsted-acid-catalyzed chemical reaction. A third aspect of the present invention relates to ionic liquids comprising a pendant nucleophilic group, e.g., an amine. Still another aspect of the present invention relates to the use of an ionic liquid comprising a pendant nucleophilic group to catalyze a nucleophile-assisted chemical reaction. A fifth aspect of the present invention relates to the use of an ionic liquid comprising a pendant nucleophilic group to remove a gaseous impurity, e.g., carbon dioxide, from a gas, e.g., sour natural gas.

Functionalized ionic liquids, and methods of use thereof

One aspect of the present invention relates to amine-functionalized task-specific ionic liquids (TSILs). In certain embodiments, the ionic liquids of the invention comprise beta-hydroxy amines, aryl amines or tertiary amines. The TSILs may be used for gas capture, capitalizing on their non-volatile nature. In certain embodiments, the captured gas is selected from the group consisting of CO, SO, CS, and NO. Another aspect of the present invention relates to a library of CO2-philic salts, which library facilitates reactive gas separation. In certain embodiments, the CO-philic salts are CO-reactive TSILs. In certain embodiments, the CO-philic salts are resinous or plastic in nature.

The present invention relates to novel ionic liquids comprising a docusate, docusate variant, or other sulfonate anion. The ionic liquids may be conveniently made via, for example, metathesis. The ionic liquids are often hydrophobic and useful in many hydrocarbon compositions, polymer compositions, and in supercritical carbon dioxide applications. The ionic liquids are capable of hindering static electricity buildup in the hydrocarbon compositions and can therefore minimize flammability and/or explosiveness.

Ionic liquids containing a sulfonate anion

One aspect of the present invention relates to 'boronium' ions that are stable, hydrophobic, room-temperature ionic liquids. In certain embodiments, ionic liquids of the instant invention are represented by the formula [XBY](n&#x2212;1)Z, wherein X refers to a Lewis base, Y refers to a substituent covalently bonded to boron, Zis a charge diffuse anion, and x is 2, 3 or 4. In certain embodiments, the ionic liquids of the instant invention are of the general type [XBY]TfN, wherein each X is independently a tertiary amine, a N-alkylimidazole or a pyridine; and each B&#x2014;X bond is a B&#x2014;N bond.
