title: [Study on separation of essential oil of Caryophylli flos from oil-in-water emulsion by microfiltration].
abstract: OBJECTIVE
  To separate essential oil of Caryophyllix flos from oil-in-water emulsion, and to enrich the essential oil by microfiltration (MF).
  
  
  METHODS
  Using membrane flux and removal rate of COD as the indicatrixes, the membrane material as well as the operating conditions containing pressure, surface speed, temperature were optimized.
  
  
  RESULTS
  The results showed that QWLM membrane of hydrophilic is the proper membrane, and the best operating conditions was at 0.06 MPa, 60 degrees C, and 150 r min(-1) stir speed.
  
  
  CONCLUSIONS
  It can be concluded that MF is a reasonable way to enrich essential oil of C. flox.
