Abstract: The present invention concerns a method and a device for processing calcinated carbon bodies such as anodes or cathodes for use in connection with electrolytic production of aluminum. The carbon bodies are processed using a rotating processing tool that includes a mainly circular disc with cutting edges mounted at its periphery. The cutting edges may be made of polycrystalline diamond (PCD) or an equivalent material. Thus, it is possible to create slots in calcinated carbon bodies in an efficient manner with low tool wear.

Abstract: A method and equipment for reducing or avoiding multiple dispersions in fluid flows each having two or more non-mixable fluid components with different specific gravities and viscosities, in particular fluid flows of oil, gas and water from different oil/gas production wells (B1-B8) in formations beneath the surface of the earth or sea. The fluid flow from each well (B1-B8), depending on whether it is oil-continuous (o/w) or water-continuous (w/o), is fed to a transport pipeline (T) so that the oil-continuous fluid flows (o/w) are supplied to the transport line (T) first and the water-continuous fluid flows (w/o) second, or the two fluid flows (o/w, w/o) are fed to two separate transport lines (T1, T2). In a preferred embodiment, the two separate transport lines (T1, T2) may be connected to a common transport line (T); the two fluid flows (o/w, w/o) are mixed before further transport and any subsequent separation in a separator.

Abstract: A device in connection with a separator for cleaning or reaming such a separator. The separator includes a tank or a body (2) with an inlet and at least one outlet (5, 6). A transport pipeline (3) is connected to the inlet for the supply of fluid that is to be separated in the separator. The transport pipeline (3) extends from the inlet through the separator body (2). Part (6) of the line that is located inside the separator body (2) is provided with perforations or slits (7) so that fluid that arrives in the transport pipeline (3) flows into the tank through the perforations/slits (7). Mechanical equipment for cleaning the transport pipeline (3) is designed to be sent from a magazine through the separator body (2) and on via a pipe loop back to the magazine.

Abstract: A method for separation of fluid, in particular oil, gas and water, in connection with the extraction of such a fluid from formations under the surface of the earth or the sea bed. The fluid is transported in a supply pipe or transport pipe (4) to a separator (1) in the form of a tubular separator body, a gravitation tank or similar. The separated components, water and oil, are passed out of the separator separately via outlet pipes. The fluid upstream of the separator (1) is subjected to shear forces so that the drops in the supply flow are torn up to form drops that are so small that the interface generally becomes new and “uncontaminated” by surfactants. The shear forces are supplied by a phase inversion device (6) in the form of a valve or similar. Water can expediently be added to the fluid upstream of the phase inversion device (6) to achieve the desired phase inversion.

Abstract: A process in connection with a pipe (1) for transforming a dispersed gas/liquid flow into laminar stratified flow. The solution involves a first set of stationary guide blades (6) arranged in the pipe (1) and designed to rotate the liquid/gas flow. The pipe (1) is, in turn, connected to a second pipe (2) with the same or a different diameter and, in the transition between the pipe (1) and the second pipe (2), there is a second set of blades or a device (8) that is designed to stop the rotation of the gas. The natural flow pattern of the gas/liquid in the second pipe (2) then becomes stratified over a predefined distance.

Abstract: A method for electrolytic production of aluminium metal from an electrolytic (3) including aluminium oxide, by performing electrolysis, with at least one inert anode (1) and at least one cathode (2) thus forming part of an electorwinning cell. The anode evolves oxygen gas and the cathode has aluminium discharged onto it in the electrolysis process, where the oxygen gas enforces an electrolyte flow pattern. The oxygen gas is directed to flow into anode grooves and is drained away from the interpolar room, thereby establishing an electrolyte flow pattern between the electrodes (1) and (2) and between over the anodes (1). The invention also concerns and anode assembly and an electrowinning cell.

Abstract: A procedure and a device in connection with the use of a wind turbine offshore, including a wind turbine (2) connected via a shaft to a generator (3), which is rotationally mounted on a tower (4), and a foundation underneath in the form of a float (6) on which the tower (4) is mounted. The float is anchored so that it can move freely in the vertical plane via an anchor or a mooring in the form of mooring lines, hinges or tethers (7). As a consequence of the effect of the waves on the float, the motion of the wind turbine will act as a damping mechanism on the motion and thus extract energy from the waves. The wind turbine's resonance period can be adjusted by adjusting the platform's center of gravity and/or the tension in the anchor with which the wind turbine is attached to the sea bed.
