Patent number: 9028785Abstract: A CO2 amine scrubbing process uses an absorbent mixture combination of an amine containing a primary amino group CO2 sorbent in combination with a non-nucleophilic relatively stronger base. The weaker base(s) are nucleophilic and have the ability to react directly with the CO2 in the gas stream while the relatively stronger bases act as non-nucleophilic promoters for the reaction between the CO2 and the weaker base. Two moles of CO2 can be taken up by the primary amine groups in a dicarboxylation reaction, affording the potential for a highly efficient scrubbing process.Type: GrantFiled: September 9, 2011Date of Patent: May 12, 2015Assignee: Exxonmobil Reseach and Engineering CompanyInventors: Pavel Kortunov, Lisa S. Baugh, David C. Calabro, Michael Siskin

Patent number: 8845886Abstract: This invention relates to a process for separating a hydrocarbon stream via a filtration process to produce an upgraded permeate stream with decreased Conradson Carbon Residue (“CCR”) content. The invention involves the modification of a porous ceramic filter by functionalizing the surface of the ceramic filter with an multi-ring aromatic-diimide polymer. Preferably, the multi-ring aromatic-diimide polymer is comprised of a multi-ring aromatic monomer component. The functionalized filters of the present invention can be used in a process to selectively separate components of a hydrocarbon stream to produce an improved permeate (or “filtrate”) product stream with a lower CCR content and improved processing capabilities.Type: GrantFiled: May 16, 2012Date of Patent: September 30, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: David C. Calabro, Dennis G. Peiffer, Benjamin A. McCool, Stanley E. Jakubowicz

Publication number: 20140178278Abstract: Systems and methods are provided for performing CO2 sorption and regeneration processes that can take advantage of phase changes between solutions of amine-CO2 reaction products and precipitate slurries, where the slurry particles can include solid precipitates formed based on the amine-CO2 reaction products. An amine solution can be used to capture CO2 from a gas phase stream. During this initial capture process, the amine-CO2 reaction product can remain in solution. The solution containing the amine-CO2 reaction product can then be exposed to a set of conditions which result in precipitation of a portion of the amine-CO2 reaction product to form a slurry. The precipitate slurry can be passed into one or more release stages where the conditions for the slurry are altered to allow for release of the CO2.Type: ApplicationFiled: November 22, 2013Publication date: June 26, 2014Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Michael Siskin, Patrick L. Hanks, Pavel Kortunov, Robert B. Fedich, Patrick P. McCall, Hans Thomann, Daniel Leta, Lisa S. Baugh, David C. Calabro, Harry W. Deckman

Patent number: 8715397Abstract: A CO2 amine scrubbing process uses an absorbent mixture combination of an amine CO2 sorbent in combination with a non-nucleophilic, relatively stronger, typically nitrogenous, base. The weaker base(s) are nucleophilic and have the ability to react directly with the CO2 in the gas stream while the relatively stronger bases act as non-nucleophilic promoters for the reaction between the CO2 and the weaker base. The sorption and desorption temperatures can be varied by selection of the amine/base combination, permitting effective sorption temperatures of 70 to 90° C., favorable to scrubbing flue gas.Type: GrantFiled: September 9, 2011Date of Patent: May 6, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Pavel Kortunov, Lisa S.

Publication number: 20120063978Abstract: Ionic liquids are capable of acting as solvents for amine CO2 absorbent compounds in CO2 separation processes and when so used enhance the sorption of the CO2 by the amine. A cyclic sorption process for separating CO2 from a gas stream, such as flue gas or natural gas, brings the gas stream into contact with an absorbent solution of an amine CO2 sorbent in an ionic liquid solvent followed by desorbing the CO2 to regenerate the amine.Type: ApplicationFiled: September 9, 2011Publication date: March 15, 2012Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Lisa S.

Publication number: 20120061614Abstract: A method is described for separating CO2 and/or H2S from a mixed gas stream by contacting the gas stream with a non-aqueous, liquid absorbent medium of a primary and/or secondary aliphatic amine, preferably in a non-aqueous, polar, aprotic solvent under conditions sufficient for sorption of at least some of the CO2. The solution containing the absorbed CO2 can then be treated to desorb the acid gas. The method is usually operated as a continuous cyclic sorption-desorption process, with the sorption being carried out in a sorption zone where a circulating stream of the liquid absorbent contacts the gas stream to form a CO2-rich sorbed solution, which is then cycled to a regeneration zone for desorption of the CO2 (advantageously at <100° C.). Upon CO2 release, the regenerated lean solution can be recycled to the sorption tower. CO2:(primary+secondary amine) adsorption molar ratios >0.5:1 (approaching 1:1) may be achieved.Type: ApplicationFiled: September 9, 2011Publication date: March 15, 2012Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: David C.
