Abstract: An apparatus for separating dispersed phases from fluid mixtures comprising a fluid separation chamber provided with a plurality of fluid outlet ports for discharge of fluids with different densities, and fluid inlet means for introducing the mixture into the chamber comprising at least one tubular neck portion in which a cluster of fibers is compressed to a fibrous bed. Each tubular neck portion is arranged to a level between the top portion and a bottom portion of the chamber and at an angle relative to the vertical thereby reducing the chance of accumulation of foamy or solid contaminants in the fibrous bed and allowing continuous removal thereof from the separation chamber.
