  • Method and separator for cyclonic separation of a fluid mixture
    Patent number: 7510597
    Abstract: A method for cyclonic separation of gaseous and liquid fractions from a multiphase fluid mixture comprises: providing a cyclonic separation vessel (1) having a bottom section (4), a top section (3) and a tubular midsection (2), which is co-axial to a central axis (5); injecting the multiphase fluid mixture into the vessel via an inlet conduit (6) which has a substantially tangential orientation relative to said central axis (5); inducing the fluid mixture to swirl within said tubular mid-section (2) of the vessel at such a speed that liquid and gaseous fractions are separated by cyclonic separation and gravity forces induce the liquid fraction to drop to the bottom section (4) of the vessel; —removing the gaseous fraction from the interior of the top section of the vessel via a gas outlet conduit (8) which has an entrance opening which is located at or near the central axis (5); removing the liquid fraction from the interior of the bottom section (4) of the vessel via a plurality of liquid outlet openings (11
