Patent number: 7459001Abstract: Vane diffuser for use in separators for separating a liquid phase and/or a particulate material from a gas flow, includes a distribution chamber that communicates with the inlet pipe stub of the separator. A top plate, a bottom plate, and a plurality of curved, parallel vanes together delimit a plurality of diffuser channels. Each of the vanes has a thickness which varies in the flow direction to ensure an even expansion of the cross-sectional area of the diffuser channels, thereby reducing reverse flow along the suction side of the vanes, as occurs with vanes of uniform thickness.Type: GrantFiled: March 4, 2005Date of Patent: December 2, 2008Assignee: Natco Norway ASInventors: Bjorn Christiansen, Knut Sveberg, Inge Hjelkrem, Dag Kvamsdal

A top plate (9), a bottom plate (10), and a plurality of curved, parallel vanes (11) together delimit a plurality of diffuser channels (13). The vanes (11) have a varying thickness in the flow direction which ensures an even expansion of the cross-sectional area of the diffuser channels (13), which implies that the fluid will not be given a reverse flow along the suction side (18) of the vanes (11) as is the case for vanes with uniform thickness.Type: ApplicationFiled: March 4, 2005Publication date: July 17, 2008Applicant: CONSEPT ASInventors: Bjorn Christiansen, Knut Sveberg, Inge Hjelkrem, Dag Kvamsdal

Patent number: 7279020Abstract: Axial flow demisting cyclone for separation of a mixture of gas and liquid including an inlet 30 for gas containing liquid droplets and an outlet 31 for substantially dry gas, including a mainly cylindrical cyclone tube 16 with at least one path of slots or perforations 19 allowing a part of the fluid, including separated liquid, to flow out of the cyclone tube 16. The demisting cyclone also includes a swirl inducing device 17, 18 to set the entering fluid in rotation. This swirl-inducing device is formed from a cascade of vanes 18 attached to a concentric core body 17, preferably cylindrical in shape, which extends towards the wall of the cyclone tube 16, the vanes 18 being in the longitudinal direction of the vanes from their leading edge 23 to their trailing edge 24.Type: GrantFiled: November 7, 2002Date of Patent: October 9, 2007Assignee: ConSept A/SInventors: Bjorn Christiansen, Knut Sveberg, Inge Hjelkrem, Dag Kvamsdal

Publication number: 20070125715Abstract: A flotation separator for the separation of a dispersed liquid phase and/or suspended solid materials from a continuous liquid phase containing free gas including; an open or closed vessel (1) which is completely or partially liquid filled, is equipped with one or several inlet nozzles (2) feeding the inflowing mixture through one or several distribution chambers (13) toward one or several substantially vertically arranged cyclone pipes (15). Each cyclone pipe (15) is equipped with a swirl generating inlet device (14), a lower exit (16) where continuous liquid phase is exiting the cyclone pipe (15), and an upper exit (17) where gas, the dispersed liquid, and/or suspended solids, together with parts of the continuous liquid phase are exiting the cyclone pipe (15). The upper exit port (17) of the cyclone pipe or pipes (15) is completely or partially submerged in the continuous liquid phase.Type: ApplicationFiled: November 24, 2004Publication date: June 7, 2007Inventors: Bjorn Christiansen, Knut Sveberg, Inge Hjelkrem, Dag Kvamsdal

Patent number: 7144437Abstract: A vertically oriented separator for separating liquid from a gas stream, where the incoming fluid enters the separator through an inlet nozzle arranged mainly perpendicular to the center axis of the separator and communicates with a circular swirl-inducing inlet device which is outwardly limited by the separator wall, inwardly limited by a mainly centrally arranged pipe and upwardly limited by a sealed top cover. The separator includes a first separation compartment arranged below the pipe and a second separator compartment arranged above the pipe, so the incoming fluid successively and under continuous swirl is forced to pass from the circular swirl-inducing inlet device to the first separator compartment and further through the pipe to the second separator compartment.Type: GrantFiled: October 18, 2002Date of Patent: December 5, 2006Inventors: Bjorn Christiansen, Knur Sveberg, Inge Hjelkrem, Dag Kvamsdal
