  • Patent number: 6582600
    Abstract: A two-stage hydrocyclone system for separating oily fluids including a first stage hydrocyclone set up to produce a concentrated oil stream, while the second stage hydrocyclone is set up to optimize the production of clean water from the dirty water underflow stream of the first stage hydrocyclone. The hydrocyclone stages are mounted within a pressure vessel with divider walls, with the first stage producing a concentrated oil stream substantially free of water and a dirty water stream containing some oil. This dirty water stream from the first stage is fed to the second stage to obtain a clean water stream.
