  1. TUSTP 2003 Evaluation of Oil-Water Flow through Piping Restrictions by Erzhan Kuantaev May 20, 2003

  2. Outline • Introduction • Objectives • Experimental Results • Conclusion • Future Work

  3. Introduction • Flow conditioning upstream of compact separators can improve their performance and separation efficiency • Study of water-oil mixture flow through different piping restrictions can help reduce droplet breakup and promote coalescence

  4. Objectives • Compare oil-water separation in Batch Separator for different restrictions • Improve design of restrictions for more efficient oil-water separation

  5. Experimental Program • Experimental Facility • Experimental Results

  10. Experimental Results Text matrix: - Orifices – square and circular - Rectangular venturi and channel - Water cut (25%, 50%, 75%) - Mixture velocities (1 - 5 ft/s)

  14. Orifice Results

  15. Venturi Results

  16. Venturi Results

  17. Venturi Results

  18. Conclusions Orifice - Separation time less for flow through circular geometry as compared to rectangular geometry - Pressure drop almost the same for both geometries

  19. Conclusions Venturi - Separation time less for venturi geometry as compared to rectangular channel - Venturi exhibits less pressure drop than rectangular channel

  20. Future Work More data needs to be acquired for higher pressure drop More studies needed to understand effect of different restriction geometries on droplet breakup/coalescence Improve instrumentations (Laser/Fiber Optic) Develop model for prediction of droplet size distribution through piping restrictions
