Patent number: 11945006Abstract: A method of cleaning deposited solid material from a fouled portion of a gas compressor (6) whilst the gas compressor (6) is in situ in a natural gas processing system (1) is provided. The method comprises the steps of supplying a liquid cleaning agent to a gas inlet of the gas compressor (6), the liquid cleaning agent being capable of removing the deposited solid material; passing the liquid cleaning agent through the gas compressor (6) to a gas outlet of the gas compressor (6), wherein at least a portion of the cleaning agent remains in a liquid state as it passes through the fouled portion of the gas compressor (6); and recovering a fluid containing removed material that is output from the gas compressor (6) so as to prevent the removed material reaching one or more gas processing stages of the gas processing system (1) downstream of the gas compressor (6).Type: GrantFiled: December 13, 2021Date of Patent: April 2, 2024Assignee: Equinor Energy ASInventors: Lars Brenne, Svend Tarald Kibsgaard, Tor Bjørge, Harald Underbakke

Patent number: 9784075Abstract: A combined multi-phase pump and compressor unit and a gas compression system are provided. The combined multi-phase pump and compressor unit functions on a centrifugal principle for transporting liquid and gas from a flow conditioner to a remote multi-phase receiving plant, wherein a rotating separator separates liquid and gas upstream of a compressor part of the combined multi-phase pump and compressor unit, wherein the separated liquid is collected in a rotating annulus in such a way that the liquid is given kinetic energy which is converted to pressure energy in a static system, and wherein the pressurized liquid bypasses the compressor part of the combined multi-phase pump and compressor unit, and then is re-mixed with the gas downstream of the combined multi-phase pump and compressor unit.Type: GrantFiled: April 24, 2015Date of Patent: October 10, 2017Assignee: STATOIL PETROLEUM ASInventors: Tor Bjørge, Lars Brenne, Harald Underbakke, Bjorn-André Egerdahl, Rune Mode Ramberg, William Bakke

Patent number: 9518588Abstract: There are described methods and apparatus for operating and/or cleaning a compressor. In an embodiment, a first fluid comprising gas may be passed through the compressor, while the compressor operates to compress the first fluid. A second fluid may be passed through the compressor, the second fluid comprising gas and liquid from at least one well. The second fluid may be passed through the compressor for a limited time period to clean a surface inside the compressor, while the compressor operates to compress the second fluid.Type: GrantFiled: June 11, 2012Date of Patent: December 13, 2016Assignee: Statoil Petroleum ASInventors: Lars Brenne, Tor Bjørge, Harald Underbakke, Svend Tarald Kibsgaard

Patent number: 9303498Abstract: Subsea apparatus (10) for processing a well stream (2) and a method of processing a well stream subsea is described. In an embodiment, liquid (5) and gas (3) contained in the well stream (2) is separated. The separated gas (3) is cooled and the cooled gas (32) is combined with the separated liquid (5) to form a wet gas (52) for a compressor (90). An active cooling arrangement (30) may be used in one example to enhance the cooling effect provided by the cooler (30). Advantageously, the apparatus (10) can be arranged compactly, and may be provided on a subsea retrievable module.Type: GrantFiled: August 6, 2012Date of Patent: April 5, 2016Assignee: STATOIL PETROLEUM ASInventors: Tom Grimseth, William Bakke, Tor Bjørge, Håvard Torpe, Håvard Eidsmoen, Birgitte Nordheim Tveter, Harald Underbakke, Lars Brenne

Patent number: 9032987Abstract: The invention relates to a wet gas compression system comprising a compact flow conditioner (21), intended to be placed below sea level in close vicinity to a well head or on a dry installation, said flow conditioner (21) being intended to receive a multi-phase flow through a supply pipe (11) from a sub sea well for further transport of such hydrocarbons to a multi-phase receiving plant, and where preferably avoid sand accumulation or remove as much sand as possible from the multi-phase flow, the gas (G) and the liquid (L) being separated in the flow conditioner (21) whereupon the separated gas (G) and liquid (L) are re-assembled and enters a multi-phase meter (46) prior to boosting by means of a compressor (22). In the combined multi-phase pump and compressor unit (22), as an integrated unit, comprises a combined multi-phase pump and compressor unit (22) functioning on the centrifugal principle, used for trans-porting liquid and gas from a flow conditioner (21) to a remote multi-phase receiving plant.Type: GrantFiled: April 2, 2009Date of Patent: May 19, 2015Assignee: STATOIL PETROLEUM ASInventors: Tor Bjørge, Lars Brenne, Harald Underbakke, Bjorn-André Egerdahl, Rune Mode Ramberg, William Bakke
