Patent number: 8574351Abstract: A two phase gas-liquid separation apparatus is provided that shapes the flow in a flow shaping line. Shaping the two-phase flow allows centrifugal force to send the heavier, denser liquid to the outside wall of the flow shaping line and allows the lighter, less dense vapor or gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall of the flow shaping line, an exit port on the inner wall will allow for the majority, if not all, of the gas, along with a low amount of liquid, to be sent to a conventional separator. A high ratio of vapor/liquid at a flow rate much lower than the total flow rate within the flow shaping line is sent to the conventional separator. This allows for efficient separation of the vapor from the liquid with the use of a smaller conventional separator.Type: GrantFiled: March 18, 2013Date of Patent: November 5, 2013Assignee: Haven TechnologyInventors: David James Elms, Gregory Allen Hudspeth

Patent number: 7578870Abstract: A fluid separator device allows for introducing air entrained in a liquid flow to a centrifugal pump in a manner that will not allow the pump to become gas bound. One example device designed according to this invention includes a housing having an inlet and an outlet downstream of the inlet. An air chamber is positioned on an opposite side of the inlet from the outlet. An air flow passage allows air from the air chamber to be introduced near a rotor assembly input of a centrifugal pump such that relatively small air bubbles are introduced to the liquid flow through the rotor assembly in a manner that prevents the air bubbles from recollecting into a larger bubble that would otherwise interfere with the centrifugal pump operation.Type: GrantFiled: December 17, 2004Date of Patent: August 25, 2009Assignee: Hamilton Sundstrand CorporationInventor: W. Clark Dean

Patent number: 7488372Abstract: The present invention relates to a process for degassing an aqueous solution containing a hydroformylation product and separating a volatile metal species from gaseous stream to inhibit or prevent deposition of a solid material from the gaseous stream. To separate the volatile metal species from the gaseous stream, the gaseous stream is either 1) contacted with a liquid that separates the volatile metal species, or a reaction product thereof, from the gaseous stream; 2) passed through a microfilter having a pore size of 2 ?m or less; or 3) contacted with an adsorbent material.Type: GrantFiled: February 1, 2006Date of Patent: February 10, 2009Assignee: Shell Oil CompanyInventors: Joseph Broun Powell, Robert Earl Hammond

Patent number: 7326283Abstract: A spinning impingement multiphase contacting device and method for heat or mass transfer are disclosed. A first fluid, from which the transfer is to occur, is caused to impinge and be entrained in a spinning permeable element, creating a highly dispersed phase. The highly dispersed phase contacts the second fluid to cause the desired heat or mass transfer.Type: GrantFiled: October 22, 2004Date of Patent: February 5, 2008Assignee: Cleveland Gas Systems, LLCInventors: Nelson C. Gardner, Xintian Zheng, Robert E. Harris

Patent number: 7282081Abstract: Disclosed is an improve aeration system. The aeration system of the present invention more efficiently removes contaminates, such as hydrogen sulfide, from water. The increased efficiency is achieved by adjusting the pH level of the water in between sequential mass transfer media stages within the aerator. The present invention also relates to an aeration system wherein the forced or induced air is used to strip contaminants from the processed water is reutilized by one or more aeration towers connected in series.Type: GrantFiled: October 6, 2004Date of Patent: October 16, 2007Inventor: John A. Verscharen

Patent number: 7018444Abstract: A system for removing and purifying a carbon dioxide-containing stream from a batch process tool is provided. A multi-phase contaminated stream containing at least carbon dioxide and one or more co-solvent is removed from a process tool and conveyed to at least one intermediate pressure separator. The contaminant-containing stream is separated into an intermediate pressure carbon dioxide-enriched vapor stream and an intermediate pressure solvent and contaminant-enriched stream in the intermediate pressure separator.Type: GrantFiled: May 7, 2003Date of Patent: March 28, 2006Assignee: Praxair Technology, Inc.Inventors: John Frederic Billingham, Thomas John Bergman, Jr., Richard Martin Kelly, Kenneth Leroy Burgers, William Thoru Kobayashi

Patent number: 6997972Abstract: A gas liquid separator comprising at least two containers, a first container for separating gas from a gas liquid mixture and a second container for receiving gas reduced or gas free liquid. The first container has an outlet port to the second container below the level of the gas for the gas reduced or gas free liquid and a separate outlet port for the separated gas. The second container has a height taller than the height of the first container to enable it to hold enough volume of the gas reduced or gas free liquid that can exert pressure on the liquid inside the first container so that the separated gas is forced to escape from the gas outlet port of the first container while allowing the gas reduced or gas free liquid to exit at a separate outlet port of the second container.Type: GrantFiled: September 10, 2003Date of Patent: February 14, 2006Assignee: Skydon Corp.Inventor: Anthony Tseng

Patent number: 6962199Abstract: The present invention relates to a method for removing condensables from a natural gas stream, at a wellhead, downstream of the wellhead choke thereof. In accordance with the invention there is provided a method for removing condensables from a natural gas stream at a wellhead, the method comprising the steps of: (A) inducing the natural gas stream to flow at supersonic velocity through a conduit of a supersonic inertia separator and thereby causing the fluid to cool to a temperature that is below a temperature/pressure at which the condensables will begin to condense, forming separate droplets and/or particles; (B) separating the droplets and/or particles from the gas; and (C) collecting the gas from which the condensables have been removed, wherein the supersonic inertia separator is part of the wellhead assembly downstream of the wellhead choke.Type: GrantFiled: December 29, 1999Date of Patent: November 8, 2005Assignee: Shell Oil CompanyInventor: Cornelis Antonie Tjeenk Willink

Patent number: 6893486Abstract: A method and system for sea-based handling/treatment of fluid hydrocarbons (oil) with associated gas include a first separation step in a high-pressure separator (18) installed on the sea bed, from which is output an oil flow containing an essentially predefined percentage of residual gas. The oil containing residual gas is carried through a riser (22) up to a surface vessel/production ship (12), where it is subjected to a second separation step in a second separator (24) incorporated in a low-pressure surface plant on board the vessel (12), this separated residual gas being used as fuel for direct/indirect generation of electric power for the operation of the underwater and above-water sections of the system. Water and gas produced in the first separation step is returned to a suitable reservoir by the use of a multiphase pump.Type: GrantFiled: April 27, 2001Date of Patent: May 17, 2005Assignees: Navion ASA, Framo Engineering AS, Kongsberg Offshore ASInventors: Morten Sanderford, Bernt Helge Torkildsen, Jens Grendstad, Egil Tveit, Olav Inderberg
