SEPARATION OF A SUSPENSION. OF TWO IMMISCIBLE FLUIDS Abstract of the Disclosure Separation of a suspension of two immiscible fluid components is accomplished in a cylindrical pressure vessel divided into a main chamber and, at one axial end, a secondary chamber. A separation device in the main chamber provides a tortuous passage for fluid to the secondary chamber. The two components tend to separate in the separation device, the less dense component collecting in the upper part of the main chamber and the denser component passing to the secondary chamber. The vessel is provided with an inlet pipe to the main chamber, a first outlet from the main chamber for the less dense component and a second outlet for the denser component exiting from the secondary chamber. The invention is characterised in that the inlet pipe enters the main chamber at a position away from the secondary chamber and is divided into a plurality of discharge pipes extending longitudinally through a space defined between the exterior of the separation device and the cylindrical wall of the main chamber and terminating adjacent the dividing wall separating the main chamber from the secondary chamber. As a result, fluid discharged from the outlet pipes must reverse its flow and travel to the opposite end of the separation device externally thereof before entering the tortuous passage. This method enables the apparatus to be more compact and efficient than prior separators having the same through-put. - 2 - The separation means is generally rectangular in external configuration in axial section of the vessel. The inlet comprises an inlet pipe which enters the main chamber at a position away from the secondary chamber, the inlet pipe being divided into a plurality of discharge pipes extending through the space between the exterior of the separation means and the cylindrical wall of the main chamber and termi- nating short of the dividing wall separating the main chamber from the secondary chamber. In the described method, the less dense component is disentrained by causing the fluid to pass by tortuous passage through a separation means, and separating such disentrained less dense component. Incoming fluid is subject first to flow division and then to flow reversal twice before passing into the separation means.
