Process and apparatus for separating two phases from each other

A separation apparatus for separating at least two phases from each other, the apparatus comprising:

• a separation container having a feed port for the stream to be treated, an outlet port for the treated stream, and, in the bottom of the separation container, an outlet port for the separated phase, and
• a cyclone system arranged inside the separation container, the system having cyclones arranged in parallel in the direction of the flow, each system having an elongate separation chamber in which the phases of the stream directed into the cyclone can be separated from each other,
• wherein the cyclone system comprises at least 10 multi-inlet cyclones arranged in parallel and in succession and in which the separated phases can be removed in the same direction;
• wherein the cyclones each have an elongate chamber along a longitudinal axis and inlets which direct a stream made up of at least two phases to enter into the elongate chamber in a substantially radial direction transverse to the longitudinal axis;
• and wherein the cyclones together form a cassette which may be installed or replaced within a larger separation container.
