Patent number: 11920784Abstract: Flare gas is recovered by varying a number of ejector legs that depends on a flare gas flowrate. The ejector legs include ejectors piped in parallel, each ejector has a flare gas inlet and a motive fluid inlet. Flare gas and motive fluid is provided to ejectors by selectively opening or closing valves. The number of ejector legs online is varied to accommodate the amount of flare gas. The controller is also programmed to direct signals to actuators attached to the valves to open or close the valves, or to change the capacity of the ejector legs so they can handle changing flowrates of the flare gas. Included is a flare gas storage system with vessels made with flexible material, when flare gas is evacuated from the vessels, pressure in the vessels is maintained by compressing the vessels with an external force.Type: GrantFiled: May 10, 2021Date of Patent: March 5, 2024Assignee: SAUDI ARABIAN OIL COMPANYInventors: Samusideen Adewale Salu, Mohamed Ahmed Soliman, Nisar Ahmad Ansari

Patent number: 11880335Abstract: Systems and methods are disclosed for implementing an event based retention schedule for a read only file. When a regular file is to be converted to an event based retention read only file, an “event-retain” property may be enabled on the file allowing the feature to be implemented. Then, that file may have its permissions changed to read only. This will allow the file to be changed to a read only file without using a default retention time. Then, once the event is triggered, the retention time may be set so the file can be scheduled for automatic deletion.Type: GrantFiled: July 31, 2020Date of Patent: January 23, 2024Assignee: NetApp, Inc.Inventors: Akshatha Gangadharaiah, Balamurugan Ramajeyam, Raman Madaan, Subhash A.

Publication number: 20220390171Abstract: While operating a compressor system equipped with compression train(s), condensate is collected from within stages of the compression train(s), and directed to a blowdown system. Gas from a later stage of the compression train is routed to the blowdown system and used to drive the condensate to a condensate destination at a pressure that avoids flashing of the condensate until it reaches the condensate destination. Inside the blowdown system the condensate is stored in a tank and directed to parallel piped vessels. Operation of the vessels includes (1) receiving the condensate, (2) pressurization with gas from a later stage of compression, (3) flowing the pressurized condensate from the vessel to the condensation destination, (4) depressurizing the vessel, and (5) repeating steps (1)-(4). A flow of condensate from the blowdown system is continuous by staggering the phases of operation between the two vessels.Type: ApplicationFiled: June 8, 2021Publication date: December 8, 2022Applicant: Saudi Arabian Oil CompanyInventors: Nisar Ahmad Ansari, Mohamed Soliman, Samusideen Adewale Salu, Talal Al-Zahrani
