<p>Apparatus (10) for separating a mixture of oil and water. The apparatus (10) comprises a cylindrical vessel (12), with a cylindrical divider (18) separating the vessel (12) into a central zone (24) and outer annular zone (22). An upper part of the divider (18) provides a weir to enable fluid in the central zone (24) to pass into the outer zone (22). A tangential inlet extends into the central zone (24) at a lower part of the vessel (12), with an outlet (36) at the upper end of the vessel (12) for oil and/or gas, and a water outlet (42) on the side of the vessel (12) a small distance above the bottom of the outer zone (22). A flotation gas inlet (44) is provided extending tangentially into the outer zone (22) to provide a second stage of flotation to pick up any oil or gas remaining in the water.</p> |
