Patent number: 11300031Abstract: Systems and methods for treating automotive vehicle emissions on board an automotive vehicle include the use of waste heat recovery, electrochemical water splitting, phototcatalytic water splitting, and selective catalytic reduction. Waste heat recovery is used to power electrochemical water splitting, or photocatalytic water splitting. Photons collected from a solar panel are used in photocatalytic water splitting, or in photo-assisted selective catalytic reduction. Hydrogen gas generated by water splitting is used in conjunction with catalytic reduction units to catalytically reduce NOx in an engine exhaust gas.Type: GrantFiled: October 21, 2019Date of Patent: April 12, 2022Assignee: Saudi Arabian Oil CompanyInventors: Christos M. Kalamaras, Esam Z. Hamad, Remi Mahfouz, Tamour Javed

Patent number: 11235281Abstract: Marine engine exhaust includes pollutants such as CO2, NOx and SOx. An onboard system and method for the simultaneous removal of these pollutants includes obtaining seawater from the water on which the marine vessel travels, purifying the seawater to remove a portion of hard ions, concentrating the seawater to yield a concentrated brine solution, treating the concentrated brine solution with a chemical softener to yield a treated brine solution, acidifying the treated brine solution, and utilizing the acidified brine solution in a chlor-alkali process to yield sodium hydroxide. The sodium hydroxide can be used in an acid gas scrubber to remove CO2, NOx, and SOx from the marine engine exhaust gas.Type: GrantFiled: July 20, 2020Date of Patent: February 1, 2022Assignee: Saudi Arabian Oil CompanyInventors: Christos M. Kalamaras, Esam Z. Hamad

Patent number: 10124294Abstract: An on-board fuel separation system includes a supply fuel tank configured to store an input fuel stream; a fuel separator fluidly coupled to the supply fuel tank and configured to separate the input fuel stream into a first fractional fuel stream and a second fractional fuel stream. The fuel separator includes a membrane that includes a plurality of pores sized based on a molecular size of one or more components of the first fractional fuel stream. The system includes a first fractional fuel tank fluidly coupled to the fuel separator to receive the first fractional fuel stream passed through the membrane and defined by a first auto-ignition characteristic value. The system includes a second fractional fuel stream coupled to the fuel separator to receive the second fractional fuel stream from the fuel separator that is defined by a second auto-ignition characteristic value that is different than the first auto-ignition characteristic value.Type: GrantFiled: June 23, 2016Date of Patent: November 13, 2018Assignee: Saudi Arabian Oil CompanyInventors: Esam Z.
