Publication number: 20230127859Abstract: A carbon dioxide (CO2) capture system to reduce CO2 emissions comprises an absorption zone and a regeneration zone. The absorption zone captures CO2 from exhaust gas by absorption in a liquid solvent separated from the exhaust gas by a separator. The liquid solvent comprises a blend of alkali metal salts of two or more amino or amino-sulfonic acids, thereby forming a first constituent and a second constituent. The first constituent is a primary or secondary amino or amino sulfonic acid with molar mass of less than 200 g/mol. The second constituent has a molar mass of less than 300 g/mol. The regeneration zone may rejuvenate the liquid solvent rich in captured CO2 by heating so that a resulting liquid solvent with a low concentration of CO2 is pumped back to the absorption zone. An on-board CO2 capture and storage system for a mobile internal combustion engine and a method for capturing CO2 are also described.Type: ApplicationFiled: October 22, 2021Publication date: April 27, 2023Applicants: ARAMCO SERVICES COMPANY, SAUDI ARABIAN OIL COMPANYInventors: Alexander Voice, Eric Latimer, Esam Zaki Hamad

Patent number: 11242785Abstract: Provided is a process that may comprise cooling an engine exhaust emissions comprising SOx on a vehicle that may come from an engine. The cooled engine exhaust emissions comprising SOx may be passed to one or more absorption units. The SOx may be extracted from the engine exhaust emissions with a sorbent supported on solid porous media in an absorption unit on the vehicle to form an absorbed SOx. The absorbed SOx may be desorbed, followed by forming one or more SOx product from the desorbed SOx. The one or more SOx product may be unloaded to an off-vehicle facility.Type: GrantFiled: June 30, 2020Date of Patent: February 8, 2022Assignee: SAUDI ARABIAN OIL COMPANYInventors: Maryam M Al-Taher, Esam Zaki Hamad, Remi Mahfouz

Patent number: 11028805Abstract: The present disclosure relates to a vehicle, system, and method for on-board catalytic upgrading of hydrocarbon fuels. In accordance with one embodiment of the present disclosure, a vehicle may include, amongst other things, an internal combustion engine configured to provide motive force to the vehicle, an unreformed fuel subsystem, a reformed fuel subsystem, and a fuel system control architecture. The unreformed fuel subsystem may be structurally configured to transfer unreformed hydrocarbon fuel from the on-board point-of-sale fuel tank to the internal combustion engine. The reformed fuel subsystem may be structurally configured to reform hydrocarbon fuel from the on-board point-of-sale fuel tank and transfer reformed fuel to the internal combustion engine along a reformed fuel supply pathway separated from the unreformed fuel supply pathway. The fuel system control architecture may include a reformate flow control device and a cetane rating controller.Type: GrantFiled: January 9, 2019Date of Patent: June 8, 2021Assignee: Saudi Arabian Oil CompanyInventors: Esam Zaki Hamad, Christos Kalamaras

Patent number: 10947461Abstract: The present invention provides selective extraction of sulfoxides, or sulfoxides in combination with sulfones, from hydrocarbon mixtures containing these compounds. A significant advantage of the invention is that oxidation products resulting from oxidative desulfurization of hydrocarbon feedstocks are selectively extracted with minimum co-extraction of non-oxidized products such as valuable hydrocarbon fuel components.Type: GrantFiled: March 27, 2019Date of Patent: March 16, 2021Assignee: Saudi Arabian Oil CompanyInventors: Emad Naji Al-Shafei, Esam Zaki Hamad

Patent number: 10801422Abstract: A vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system may selectively receive and separate at least a portion of onboard fuel and a flowable adsorbent in order to separate the fuel into octane-enhanced and cetane-enhanced fuel components. A controller may be used to determine a particular operating condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit during one operating condition, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture in another operating condition.Type: GrantFiled: August 26, 2019Date of Patent: October 13, 2020Assignee: Saudi Arabian Oil CompanyInventors: Esam Zaki Hamad, Eman AbdelHakim A.

Patent number: 10760507Abstract: A vehicular propulsion system, a vehicular fuel system and a method of producing fuel for an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based reaction chambers to selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced components. Regeneration of an adsorbate takes place through interaction with a solvent, while subsequent separation allows the solvent to be reused. A controller may be used to determine a particular operational condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture.Type: GrantFiled: July 24, 2019Date of Patent: September 1, 2020Assignee: Saudi Arabian Oil CompanyInventors: Esam Zaki Hamad, Eman AbdelHakim A.

Patent number: 10598100Abstract: A vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced fuel components. A supply tank includes three compartments where the first contains the onboard fuel, the second receives a vaporized adsorbate from the separation unit and condenses at least a part of it into one of an octane-rich fuel component or a cetane-rich fuel component, while the third may either store the condensed and enriched fuel component or help condense more of the vaporized adsorbate. The condensing takes place through heat exchange between the onboard fuel and the vaporized adsorbate that are present within the various compartments of the supply tank.Type: GrantFiled: June 26, 2019Date of Patent: March 24, 2020Assignee: Saudi Arabian Oil CompanyInventors: Esam Zaki Hamad, Eman AbdelHakim A.
