  • Patent number: 8778159
    Abstract: A method of separating oil and water in a flow-stream through a gravity settling vessel (10) in which the flow-stream (12) separates into a lower water layer (22) and an upper oil layer (26), includes feeding an off-take stream (34) of the oil layer and/or an emulsion layer (20) that forms between the oil layer and the water layer through a compact electrostatic coalescer (CEC) (38) that has electrically isolated electrodes. The CEC coalesces water droplets in the off-take stream, and the coalesced off-take stream is then returned to the settling vessel. An associated separator apparatus for comprises: a gravity settling vessel (10); a CEC (38) including electrically isolated electrodes; a coalescer feed line (34) configured to provide an off-take stream of an oil phase and/or an emulsion layer from the settling vessel to the CEC; and a return line (40) from the CEC for returning the off-take stream to the settling vessel.

  • Patent number: 8269590
    Abstract: A system for high power transmission on an installation comprising a first part (1, 11) and a second part (2, 12) rotating relative to each other characterized in that the system further comprising a rotary three-phase transformer having primary (U1, V1, W1) and secondary (U2, V2, W2) windings, the first part being provided with one of said primary (U1, V1, W1) or secondary (U2, V2, W2) windings, the second part being provided with the remaining winding of said primary (U1, V1, W1) or secondary (U2, V2, W2) windings, said primary (U1, V1, W1) and secondary (U2, V2, W2) windings are arranged to face each other, and an air gap (6) is provided between the primary (U1, V1, W1) and secondary (U2, V2, W2) windings and their corresponding parts of the transformer cores.

  • Publication number: 20110139624
    Abstract: A compact desalting system for use in a process of desalting crude oil comprises a plurality of separation stages. Each separation stage includes a compact electrostatic coalescer (42, 62) for coalescing water droplets carried with the crude oil and settling means (91, 92; 95, 96) for settling separated oil and coalesced water droplets. The system includes a vessel (46) comprising a plurality of compartments containing the settling means and the compact electrostatic coalescers are each mounted in a housing on top of the vessel.

  • Publication number: 20080237140
    Abstract: A fluid phase distribution adjuster (10) comprises two or more tubes (14) arranged to provide a plurality of separate flow paths for fluid. Means are provided for generating a radial acceleration of fluid flowing through each tube so as to promote movement of at least one fluid phase towards or away from a wall of the tube. The adjuster can be used as a coalescer for increasing the size of droplets in a distributed fluid phase carried by a continuous fluid phase, or as a mixer for mixing fluid phases.
