International ClassesB01D 017/12B01D 017/038 AbstractThis invention relates to a system for separating a multiphase liquid mixture into a plurality of streams. The invention has particular utility in the oil industry where particulate solids are produced with an oil/water mixture. Preferably, the mixture is first cyclonically separated to remove particulate solids from the oil and water. Then the mixture is delivered to a liquid/liquid hydrocyclone where a substantial portion of the oil is separated from the remaining mixture which now primarily comprises water. The pressure of the remaining mixture is elevated such as by a pump and is then subjected to a further cyclonic separation step to remove any remaining fine solids in the mixture.Field of SearchMaterial level or thickness responsiveFLOW, FLUID PRESSURE OR MATERIAL LEVEL, RESPONSIVE Responsive to material level Serially connected distinct treating or storage units With pump, gas pressure or vacuum source Diverse TANGENTIAL FLOW OR CENTRIFUGAL FLUID ACTION Multiple cyclone GRAVITATIONAL SEPARATOR Level sensing Including geographic feature (e.g., drainage ditch, septic, pond) Cyclonic, or centrifugal (e.g., whirling or helical motion or by vortex, etc.) Introducing liquid tangentially And additional diverse separation And recirculating liquid Plural separating Including specified pressure change Separating outside of well Tangential gas inlet opening in casing Tangential gas inflow (e.g., cyclone, etc.) | |
