Pall AquaSep™ Coalescer

A multiple stage system, the Pall AquaSep coalescer first removes particulate matter, then coalesces and separates the water from a hydrocarbon stream. An AquaSep coalescer will remove entrained water to a level of 15 ppmv and below, over a wide range of conditions:
  • Water concentration as high as 3% water by weight (i.e., 30,000 ppmv).
  • Interfacial tension as low as 3.0 dynes/cm.

Pall's AquaSep liquid/liquid coalescer is compatible with refined products including:

  • All gasolines
  • Diesel
  • Kerosene
  • Lube oils
  • Aromatics
  • Petrochemicals

FEATURES FUNCTIONS BENEFITS
High efficiency coalescing Separates "freewater" from hydrocarbons (e.g., fuels);
Up to 3% water (30,000 PPMV);
Entrained water removed is removed to less than 15 PPMV.		 Fresh fuel;
Reuse of cleaned fuel;
Disposal of water component of waste stream.
Proprietary coalescing medium Resists "disarming" by surfactants because of glass fibers; Will separate with interfacial tension as low as 3.0 dynes/cm. Continued operations and performance effectiveness.
Stacked design Uniformly distributed;
Streamlines avoided;
Deadspots avoided.		 High flow rate;
Efficiency enhanced;
Useful life extended;
Small size.
Wide compatibility Constructed of materials compatible with a wide range of petroleum products, e.g., all gasolines, including J.P-8+100, diesel fuel, kerosene, lube oils, aromatics, petrochemicals. Many applications to industrial processes and waste stream minimization.
