Publication number: 20240017204Abstract: Systems and methods are provided for operating a combined cycle power plant while enhancing the CO2 content of the flue gas generated by the power plant. The CO2 content is enhanced by using a combination of exhaust gas recycle and oxygen-enriched combustion. The oxygen-containing flow for performing the oxygen-enriched combustion can be generated by an integrated pressure swing adsorption process that allows for production of a commercial grade nitrogen stream (95 vol % or more of N2) while also providing an oxygen-containing stream with an oxygen content between 25 vol % and 48 vol % with high 02 recovery.Type: ApplicationFiled: July 10, 2023Publication date: January 18, 2024Inventors: David C. Calabro, Edward W. Corcoran, JR., Neel Rangnekar, Yu Wang

Publication number: 20230182064Abstract: This disclosure relates to the adsorption and separation of carbon dioxide in a feed stream (e.g., natural gas) using zeolite ITQ-55 as the adsorbent. A process is disclosed for removing impurities such as carbon dioxide and nitrogen while producing a hydrocarbon product. The process involves passing a feed stream through a bed of an adsorbent comprising zeolite ITQ-55 to adsorb carbon dioxide from the feed stream, thereby producing a product stream depleted in carbon dioxide. The zeolite ITQ-55 has a mean crystal particle size within the range of from about 0.1 microns to about 100 microns. The feed stream is exposed to the zeolite ITQ-55 at effective conditions for performing a kinetic separation, in which the kinetic separation exhibits greater kinetic selectivity for carbon dioxide than for methane or nitrogen. The system and method of this disclosure are particularly suitable for use with feed streams in excess of 10 MMSCFD utilizing rapid cycle PSA operations by tuning crystals size.Type: ApplicationFiled: July 26, 2022Publication date: June 15, 2023Inventors: Yu Wang, Edward W. Corcoran, JR., Avelino Corma Canos

Publication number: 20230183589Abstract: This disclosure relates to the adsorption and separation of nitrogen in a feed stream (e.g., natural gas) using zeolite ITQ-55 as the adsorbent. A process is disclosed for removing impurities such as nitrogen while producing a high pressure hydrocarbon product. The process involves passing the feed stream through a bed of an adsorbent comprising zeolite ITQ-55 to adsorb nitrogen from the feed stream, thereby producing a product stream depleted in nitrogen at pressure as feed condition without need of recompression. The zeolite ITQ-55 has a mean crystal particle size within the range of from about 0.01 microns to about 40 microns. The feed stream is exposed to the zeolite ITQ-55 at effective conditions for performing a kinetic separation, in which the kinetic separation exhibits greater kinetic selectivity for nitrogen than for methane. The system and method of this disclosure are particularly suitable for use with feed streams utilizing rapid cycle PSA operations.Type: ApplicationFiled: July 26, 2022Publication date: June 15, 2023Inventors: Yu Wang, Edward W.

Publication number: 20230182066Abstract: This disclosure relates to the adsorption and separation of fluid components, such as oxygen, in a feed stream, such as air, using zeolite ITQ-55 as the adsorbent. A process is disclosed for adsorbing oxygen from a feed stream containing oxygen, nitrogen and argon. The process comprises passing the feed stream through a bed of an adsorbent comprising zeolite ITQ-55 to adsorb oxygen from the feed stream, carrying out an equalization step to improve recovery, thereby producing a nitrogen product stream depleted in oxygen as well as a waste stream can be collected to have enriched oxygen. The kinetic selectivity and related mass transfer rates can be tuned by varying the mean crystal particle size of zeolite ITQ-55 within the range of from about 0.1 microns to about 40 microns, or by varying the adsorption temperature within the range from about -195° C. to about 30° C., or by varying the adsorption pressure within the range from about 1 bar (~14.7 psi) to about 30 bar (~435 psi), or combinations thereof.Type: ApplicationFiled: July 26, 2022Publication date: June 15, 2023Inventors: Yu Wang, Edward W. Corcoran, Jr., Pavel Kortunov, Avelino Corma Canos

Publication number: 20190300801Abstract: Systems and methods are provided for performing multistage naphtha reforming with intermediate separation of aromatics using a swing adsorption process. Use of a swing adsorption process can allow aromatics to be selectively removed from the intermediate reforming effluent while reducing or minimizing the energy costs for cooling and subsequent reheating of the intermediate reforming effluent. The resulting aromatics-rich stream generated from swing adsorption can have a substantially higher aromatics content than an aromatics-rich stream generated by conventional separation methods during multi-stage naphtha reforming. In some aspects, selective thermal purging (either hot or cold) can be used to further facilitate adsorption or desorption of components by the adsorbent in the swing adsorption vessel.Type: ApplicationFiled: March 19, 2019Publication date: October 3, 2019Inventors: Narasimhan Sundaram, Hans Thomann, Edward W. Corcoran, JR.

Patent number: 10143960Abstract: A staged complementary pressure swing adsorption system and method for low energy fractionation of a mixed fluid. Two beds in a four-column PSA system are selective for component A, and another two columns are selective for component B. The cycle creates an intermittent A and B product, using the purge effluent from the complementary product fed at an intermediate pressure. This intermittent product is used as purge gas for low-pressure purged elsewhere in the cycle using appropriate storage tanks. The use of an intermediate pressure in this cycle enables continuous production of purified component A and B without the use of compressors. Columns may also be configured to enable pressure to equalize between complementary columns.Type: GrantFiled: November 1, 2016Date of Patent: December 4, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Narasimhan Sundaram, Hans Thomann, Edward W. Corcoran, Jr.

Patent number: 10071337Abstract: Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a staged complementary swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.Type: GrantFiled: November 1, 2016Date of Patent: September 11, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Narasimhan Sundaram, Hans Thomann, Edward W.
