Application

 

Treatment of contaminated vapour streams

Adsorption of volatile organic compounds (VOCs) in filtration media

 

Used in a wide variety of applications including treatment of off-gases from:

  • air strippers
  • soil vapour extraction where VOC concentration is low
  • soil pile venting
  • industrial processes

 

Features and Specifications

 

Standard features of all filter vessels includes: carbon steel construction; internal air distribution by piping or plenum floor; epoxy internal coating; skid mounting with forklift slots.

 

A range of standard size vessels suit most applications.  Custom sizing is available. 

 

Vessels are shipped filled with filter media of choice - typically vapour phase granulated activated carbon (V-GAC).

 

HIGH PRESSURE VESSELS - ROUND

 

  • Working pressure to 70kPa;  maximum vacuum to -95 kPa
  • A range of vessel capacities available:
    • from 'small'  - vessel diameter 0.6 m,  air flow rating 110 - 320 m3/hour,  holding approx 110kg V-GAC
    • to 'large'  - vessel diameter 2.1 m, air flow rating 1000 - 3000 m3/hour,  holding approx 1,350 kg V-GAC
  • Internal air distribution via PVC piping or custom build with plenum floor
  • Upward flow of vapour stream

  

LOW PRESSURE VESSELS - SQUARE / RECTANGULAR

 

  • Working pressures range from 5kPa to 20kPa, variable with vessel size.
  • A range of vessel capacities available:
    • from 'small' -  200L drums, air fow rating 100 - 300 m3/hour, holidng approx 70kg V-GAC
    • to 'large' - modified 40' shipping containers,  air flow rating 34,000 m3/hour, holding up to 16 MT GAC, 
  • Standard internal air distribution via a plenum floor
  • Upward flow of vapour stream

 

FILTER MEDIA

 

Typical filter media is vapour phase granulated activated carbon (GAC) 4 x 8 mesh.  

Coconut based GAC is ideal for adsorption of most light end hydrocarbons.  Either virgin or reactivated GAC.

Alternatives are available, including GAC in pelleted form.

 

Ordering

 

Vessel capacities are determined by specific project parameters.
