Patent number: 9901847Abstract: A system for separating an input fluid flow comprising gas and liquid into separate gas and liquid flows is provided. The system includes a primary separator configured to receive the input fluid flow and to separate the input fluid flow into a primary separator liquid output flow and a primary separator gas output flow, a first secondary inline separator connected downstream from the primary separator to polish the primary separator gas output flow, a second secondary inline separator connected downstream from the primary separator to polish the primary separator liquid output flow, a system gas outlet, a system liquid outlet, a primary separator gas output valve on the primary separator gas output flow, and a control system configured to receive measurements of liquid level within the primary separator, and identify, using the received measurements, whether a position of the primary separator gas output valve is to be changed.Type: GrantFiled: December 22, 2011Date of Patent: February 27, 2018Assignee: STATOIL PETROLEUM ASInventors: Jan Høydal, Olav Kristiansen, Gisle Otto Eikrem, Kjetil Fjalestad

Patent number: 6752860Abstract: An apparatus for separation of the fluid flow flowing through a pipeline into a light fraction and a heavier fraction has a tubular casing (2) arranged to constitute a section of the pipeline proper, a spin element (5) for rotation of the fluid flow at the upstream end of the casing (2), and a discharge element (12) downstream of the spin element (5) having opening (13) for discharge of the light fraction and possibly entrained heavier fraction. The apparatus also has a control separator (25) connected to the discharged element (12) and arranged to separate entrained heavier fraction from the light fraction, and a control system including a level transmitter (42) indicating the level of separate heavier fraction in the separator, and a level control unit (43) connected to the level transmitter (42) and to a drain valve (40, 41) in a separator outlet (28) for the light fraction.Type: GrantFiled: August 9, 2002Date of Patent: June 22, 2004Assignee: Statoil ASAInventors: Jan Hoydal, David Stanbridge

Patent number: 6544420Abstract: A tube apparatus for outlet of liquid from a container, adapted to receive at least two different fluids with intermediate interface(s), where liquid outlet openings are located above and/or underneath the interface(s). At least one tube member is adapted to have a substantially horizontal position in the container and is provided with at least two liquid outlet openings. A collecting tube communicates with each tube member and serves to lead liquid out of the container. Immediately under and/or over each liquid outlet opening there is provided a plate-shaped flow control element which extends approximately horizontally in all directions with respect to the liquid outlet opening concerned.Type: GrantFiled: February 28, 2001Date of Patent: April 8, 2003Assignee: Den Norske Stats Oljeselskap A.S.Inventors: Jan Høydal, Per Farstad
