Publication number: 20130180401Abstract: A system for separating fluids of a fluid mixture including a filter element operatively arranged for enabling a first component of a fluid mixture to flow therethrough while impeding flow of at least one other fluid component of the fluid mixture. An additive is configured to improve a first affinity of the filter element for the first component relative to a second affinity of the filter element for the at least one other fluid component of the fluid mixture. A method of separating fluids is also included.Type: ApplicationFiled: January 13, 2012Publication date: July 18, 2013Applicant: BAKER HUGHES INCORPORATEDInventors: Jiaxiang Ren, David P. Gerrard, John C. Welch, James E. Goodson

Patent number: 8449767Abstract: An oil reservoir having an oil inlet fitting and at least one oil outlet fitting for connecting to a hydraulic system. The reservoir comprising a housing having a lower housing part and a reservoir cover which is connected to the lower housing part and includes an integrated oil filter. An oil filler neck, which can be closed by a cap, is configured on the housing cover. The reservoir housing is equipped with at least one guide element which is attached to at least one inside wall of the reservoir housing and forms a circular guidance track for the oil. This guidance track forces the oil flow in a circular manner, after entering the reservoir and passing through the oil filter but before exiting the oil reservoir, such that any air which may be present is separated from the oil and can exit the oil reservoir via an air outlet.Type: GrantFiled: November 13, 2008Date of Patent: May 28, 2013Assignees: Robert Bosch GmbH, ZF Friedrichshafen AGInventors: Uwe Renner, Christoph Lipp, Rolf Karlstedt

Patent number: 8440077Abstract: A combined degassing and flotation tank for separation of a water influent containing considerable amounts of oil and gas. A rotational flow is created in the tank which forces the lighter components such as oil and gas droplets towards an inner concentric cylindrical wall where they coalesce and rise to the surface of the liquid and are removed via the outlet. The heavier particles are forced down and sink to the lower part where they can be removed as a sludge. The water is discharged via an outlet in the lower part of the tank. The combined degassing and flotation tank is particular suited for use in oil production at sea for removal of oil and gases from water streams before the water is returned to the sea.Type: GrantFiled: February 21, 2012Date of Patent: May 14, 2013Assignee: Schlumberger Norge ASInventor: Stein Egil Oserød

Publication number: 20130108972Abstract: A separator assembly (1c) in the form of a flare tank for separating and igniting gas from non-gaseous components of a fluid stream (such as a well return). The separator assembly (1c) comprises: at least one degasser (4) having a fluid stream inlet (41) for introducing the fluid stream (well return) into a vessel (40) of the degasser (4) at a reduced velocity, and optionally a degasser gas pressure relief system (60) and non-gaseous component filter (40); a tank (3) having a settling compartment (30) and a suction compartment (31); and a flare (5c) for igniting gas leaving the degasser (4).Type: ApplicationFiled: July 15, 2011Publication date: May 2, 2013Applicant: AUSTRALIAN RIG CONSTRUCTION HOLDINGS PTY LTDInventors: Guido Stangherlin, Allan Douglas Bougoure

Publication number: 20130074798Abstract: A tray for de-aeration of oil contained in an oil pan including an inner surface, an outer surface, and a side surface. The inner surface is adapted to face a bottom surface of the oil pan. The outer surface is adapted to face an oil-gas interface of the oil contained in the oil pan. The side surface extends from the inner surface. Moreover, the side surface encloses a submerged surface to collect aeration bubbles present in the oil.Type: ApplicationFiled: September 28, 2011Publication date: March 28, 2013Applicant: Caterpillar Inc.Inventor: Bradley J.

Patent number: 8292990Abstract: A High Performance Liquid Chromatography (HPLC) system including a pressure reducer assembly for reducing pressurized streams to ambient pressure. The pressure reducer assembly includes first and second flow restrictors, each coupled to a common chamber that acts as a surge suppressor that mitigates pressure spikes in the discharge lines. The flow restrictors may comprise tubes having a high length-to-diameter ratio. The pressure losses through the flow restrictors, in combination with transition losses as the flow stream enters and exits the chamber, are sufficient to reduce a discharge stream from a specified inlet pressure to substantially ambient pressure, thus eliminating the need for pressurized waste containers.Type: GrantFiled: September 8, 2009Date of Patent: October 23, 2012Assignee: TSI, IncorporatedInventors: Michael Schumacher, Robert Montividas

Publication number: 20120260802Abstract: A gas and liquid mixture separation and collection system for zero gravity operation that can be applied to a urinal toilet is disclosed. There is an inlet to receive the gas and liquid mixture. The mixture is directed to a filter having an air side. A vacuum pump on the air side of the filter generates a pressure delta to force the inlet flow. A peristaltic pump is used to transfer liquid away from the filter surface. In doing so, the flow on the liquid side of the membrane filter may contain some gas left over from the inlet flow mixture, but there is substantially less gas than in the gas and liquid mixture at the inlet. The filtered mixture is directed to an expandable collection bag that is attached to the air side of the filter so the filter process can be repeated to remove more gas from the mixture.Type: ApplicationFiled: April 15, 2011Publication date: October 18, 2012Inventor: Jay Ingham

Patent number: 8261947Abstract: An emissions device for use with a portable fuel container assembly is provided. The emissions device includes an emissions housing configured to be mounted to the portable fuel container. The emissions housing defines at least one device opening. A membrane is supported by the emissions housing and allows the passage of the vapor and prevents the passage of a liquid. An emissions filter is also located within the emissions housing and is located such that vapor exiting through the device opening must pass the emissions filter.Type: GrantFiled: May 19, 2009Date of Patent: September 11, 2012Assignee: Eaton CorporationInventor: Matthew Lorenz Erdmann
