This invention relates generally to cyclone separators. The separator of the present invention may find application in removing a lighter phase from a large volume of a denser phase, such as oil from water, with minimum contamination of the more voluminous phase. Generally, cyclone separators are designed for the opposite purpose, that is, removing a denser phase from a large volume of a lighter phase, with minimum contamination of the less voluminous phase. In one form of the present invention, a typical starting liquid-liquid dispersion would contain under 1% by volume of the lighter (less dense) phase, but it could be more.

A cyclone separator for the separation of a mixture including multiphase liquids, the separator comprising a primary portion having generally the form of a volume of revolution and having a first end and a second end, the diameter d2 at said second end being less than the diameter d1 at said first end, a single inlet with at least a tangential component at said first end of said primary portion for introducing the mutiphase mixture to be separated into the cyclone separator and at least two outlets; characterized in that the following relationship applied: where d1 is the diameter of the cyclone in the inlet portion where flow enters (but neglecting any feed channel), di is twice the radius at which flow enters the cyclone (i.e. twice the minimum distance of the tangential component of the inlet center line from the axis), do is the diameter of said overflow outlet, Ai is the cross-sectional area of the inlet at entry to the cyclone in a plane parallel to the axis of the cyclone and perpendicular to the component of the inlet center line not parallel to the cyclone axis, d2 is the diameter of the primary portion at said second end and is measured at a point z2 where the condition first applies that: [Figure] for all z greater than z2 where z is the distance along the cyclone separator axis downstream of the plane containing the inlet and d is the diameter of the cyclone at z, then [Figure] is from 3 to 12.
