Small Flow Gas Coalescing Assembly

Description
Small Flow Gas (SFG) Coalescing Assemblies are rugged, inexpensive, high efficiency assemblies that eliminate problems caused by oil, water, and dirt in air or gas.

SFG Coalescer Features
Positive Seal:Standard seal material is Nitrile (H13) available as either an internal o-ring or flat gasket depending on coalescer size.

Outer Drainage Layer: Drainage of coalesced liquid and protection from re-entrainment is provided by a polymeric outer drainage layer. This ensures consistent, high efficiency performance.

Metal Support Core: Axial strength and protection against liquid slugs are provided by a perforated inner support core constructed of
304 stainless steel.

Outer Cage: Media support during operation is provided by a 304 stainless steel outer support cage.

Primary Coalescer: Coalescing is achieved by use of a high area pleated glass fiber medium that is surrounded by a non-woven polymeric support and drainage layers. A patented surface treatment is used that enhances coalescer performance and lowers fouling tendency and pressure drop.

End Caps: 304 stainless steel end caps are used to improve cartridge strength and prevent contaminant bypass.

Key Benefits

  • Protects process analyzers
  • Safeguards instrument air operated equipment and systems
  • Prevents orifice plugging in pneumatic controllers
  • Improves accuracy of gas measurements in the field or plant
  • Decreases freeze-out and corrosion problems
  • Reduces fouling in small gas-driven engines
  • Provides reproducible high-quality gas for all operations using produced gas

Performance

Performance Specifications

  • Removal of 99.99% of all aerosols 0.3 microns and larger. Typical downstream aerosol concentrations are less than 0.003 ppm.
  • Patented surface treatment that prevents liquids from wetting the coalescer media allowing for higher gas flow capacity and lowered fouling tendency and differential pressure.
  • Consistent performance using thin fibers and fixed pore construction optimized for efficient coalescing.
  • Long service life due to pleated media structure and surface treatment.
  • Low energy losses with typical saturated pressure drop of 1.2 psid (82.7 mbard).
  • Wide range of compatibility for use with process gases, compressor oils, hydrocarbon condensates, and water.

 

   
   
   

To calculate the pressure drop for other process conditions use the
following equation:

∆P = KH QA2 ρ + KC QA µ

where:  ∆P:  pressure drop in psid 
  KH housing pressure drop constant 
  QA actual flow rate in acfm 
  ρ:  gas density at operating conditions in lb/ft3 
  KC coalescer pressure drop constant 
  µ:  gas viscosity at operating conditions in cP
