Patent number: 10808180Abstract: Systems and methods of integrated gas oil separation are disclosed. Systems include a high pressure production trap (HPPT), a low pressure production trap (LPPT), a low pressure degassing tank (LPDT), a first knockout drum (KOD) fluidly coupled to the LPDT and operable to accept an atmospheric pressure off-gas from the LPDT, an atmospheric pressure compressor fluidly coupled to the first KOD and operable to compress the atmospheric pressure off-gas to introduce the atmospheric pressure off-gas from the LPDT into the LPPT inlet feed stream, a second KOD fluidly coupled to the LPPT and operable to accept a low pressure off-gas from the LPPT, and a low pressure compressor fluidly coupled to the second KOD and operable to compress the low pressure off-gas to introduce the low pressure off-gas from the LPPT into the crude oil inlet feed stream.Type: GrantFiled: June 13, 2018Date of Patent: October 20, 2020Assignee: SAUDI ARABIAN OIL COMPANYInventors: Mohamed Soliman, Samusideen Adewale Salu, Talal Al-Zahrani, Nisar Ahmad K.

Patent number: 10671099Abstract: A system and method for dispensing an injection material to an injection point. The injection material is stored in a tank and disposed to parallel piped vessels. An orifice is disposed in piping connected to discharge ends of the vessels, and has an opening with a designated cross sectional area. A high pressure fluid drives the injection material to the injection point; the pressure of the high pressure fluid is regulated with a pressure control valve. Valves in the inlet and discharge piping connected to the vessels are selectively opened and closed so that injection material flows to and from the vessels. Vessels vent to a recycle/recovery system to reduce vessel pressure enabling refilling with injection material. Valves in the pressurizing and depressurizing lines are selectively opened and closed to depressurize and refill the vessels to have continuous chemical injection to the injection location.Type: GrantFiled: January 9, 2018Date of Patent: June 2, 2020Assignee: SAUDI ARABIAN OIL COMPANYInventors: Nisar Ahmad K. Ansari, Samusideen Adewale Salu, Talal Al-Zahrani, Mohamed Soliman

Publication number: 20200011530Abstract: A system and method for recycling flare gas back to a processing facility that selectively employs different numbers of ejector legs depending on the flare gas flowrate. The ejector legs include ejectors piped in parallel, each ejector has a flare gas inlet and a motive fluid inlet. Valves are disposed in piping upstream of the flare gas and motive fluid inlets on the ejectors, and that are selectively opened or closed to allow flow through the ejectors. The flowrate of the flare gas is monitored and distributed to a controller, which is programmed to calculate the required number of ejector legs to accommodate the amount of flare gas. The controller is also programmed to direct signals to actuators attached to the valves, which open or close the valves to change the capacity of the ejector legs so they can handle changing flowrates of the flare gas.Type: ApplicationFiled: September 16, 2019Publication date: January 9, 2020Applicant: Saudi Arabian Oil CompanyInventors: Samusideen Adewale Salu, Mohamed A. Soliman, Nisar Ahmad K. Ansari

Patent number: 5386467Abstract: This invention relates to a method and apparatus for improving the performance of intelligent networks. In a departure from the prior art, when a data base system, such as a service control point, receives an inquiry from a switching system, if the data base system recognizes that it cannot provide the complete data requested by the inquiry, it directly launches another inquiry to another data base system to provide the missing data. Advantageously, such an arrangement reduces the number of messages transmitted among switching systems and data base systems.Type: GrantFiled: July 31, 1992Date of Patent: January 31, 1995Assignee: AT&T Corp.Inventor: Nisar Ahmad
