Patent number: 11795069Abstract: A phase separator apparatus includes a fluid flow pathway and a phase separator. The fluid flow pathway includes a fluid inlet and a fluid outlet. The fluid flow pathway is configured to flow multiphase fluid including an oil phase and a water phase from the fluid inlet to the fluid outlet. The phase separator is spatially positioned relative to the fluid flow pathway to receive the multiphase fluid flowing from the fluid outlet. The phase separator includes a mounting substrate and a separation layer attached to the mounting substrate. The separation layer includes a material switchable between oleophilic and hydrophobic under a first condition and oleophobic and hydrophilic under a second condition. The separation layer is configured to separate the oil phase and the water phase when the separation layer is under either the first condition or the second condition.Type: GrantFiled: March 19, 2020Date of Patent: October 24, 2023Assignee: Saudi Arabian Oil CompanyInventor: Zeyad Tareq Ahmed

Patent number: 11707708Abstract: A method for capturing carbon dioxide includes contacting a carbon dioxide lean gas mixture with water. One or more acid gas impurities may pass from the carbon dioxide lean gas mixture to the water to form a gas mixture and an aqueous effluent. The gas mixture is passed to a pressure swing adsorption system or a temperature swing adsorption system to increase a concentration of carbon dioxide in the gas mixture to form a carbon dioxide enriched gas mixture. The carbon dioxide enriched gas mixture is contacted with the aqueous effluent in a carbon dioxide scrubber. Carbon dioxide passes from the carbon dioxide enriched gas mixture to the aqueous effluent to form a stripped gas and acid gas enriched water. The acid gas enriched water is passed to a reactive rock formation. The one or more acid gas impurities and carbon dioxide are mineralized and permanently sequestered.Type: GrantFiled: October 15, 2021Date of Patent: July 25, 2023Assignee: Saudi Arabian Oil CompanyInventors: Zeyad Tareq Ahmed, Serguey Viktorov Arkadakskiy, Noushad Kunnummal
