Abstract: The present invention relates to an apparatus for separation of high volume flows of mixtures provided with at least two immiscible phases, especially for the first separation steps of flows of water/oil/gas/sand mixture that enter the apparatus as a wellstream mixture. The invention also relates to a method for separation of high volume flows of mixtures provided with at least immiscible phases.

Abstract: The invention relates to a device for electrostatic coalescence of liquid particles in a flowing fluid mixture, comprising: a tube having an feed opening located at the front side of the tube and a discharge opening located on the opposite side of the tube and a least one arrangement with flow guide vanes arranged in the tube, positioned in between the opened infeed side and an opposite opened outfeed side, for reducing the turbulence or for imparting a rotating movement to the fluid mixture flowing through the tube. The invention also relates to a method for electrostatic coalescence of liquid particles in a flowing fluid mixture.

Abstract: A cyclonic fluid separator has a tubular housing (10) in which the fluid is accelerated and swirl imparting means (2) for inducing the fluid to swirl through an annular space between the housing and a central body (1) mounted within the housing (10), wherein a low pressure fluid (80) is injected through a central opening (82) in the central body (1).

Abstract: The invention relates to a cyclonic separator comprising a throat portion (4) arranged between a converging fluid inlet section and a diverging fluid outlet section, to generate a swirling fluid flow in a downstream direction. The diverging fluid outlet section comprises an inner primary outlet (7) for condensables depleted fluid components and an outer secondary outlet for condensables enriched fluid components (6). The cyclonic separator comprises a volute diffuser (9, 9?) connected to one of the outlets (6, 7), which comprises a volute outlet duct (90, 90?) defined by a volute axis (I1), forming a spiral shape around the central axis (I). The outlet duct (90, 90?) comprises a vortex chamber 95. The vortex chamber is provided to transform axial momentum of the swirling fluid flow with respect to the central axis (I) into tangential momentum with respect to the volute axis (I1).
