Carbon Adsorbers - Carbon Adsorption System - Vapor Degreasers

Carbon Adsorption Systems

During the cleaning process, a vapor degreaser can release potentially toxic solvent emissions; this problem is more common in large-scale vapor degreasing operations, such as tube or auto part degreasing which use bulk chlorinated solvents like Perchloroethylene or Trichloroethylene.

Carbon adsorbers exhaust the solvent-filled air (byproduct of a degreasing operation) into carbon beds, which then adsorb the solvent. After the adsorption process, the air can be released into the atmosphere with little-to-no solvent remaining. The carbon beds are then steam-stripped and made ready for further use. However, it's important to be conscious of a solvent's acid acceptance level during carbon adsorption, as this process tends to remove the stabilizer molecules present in an azeotropic mixture in the solvent vapors.

How It Works

The carbon adsorption process consists of passing a solvent laden air stream through a bed of activated carbon. The solvent is adsorbed onto the surface of the carbon granules and the purified air exhausted. Depending on operating conditions and type of solvent involved, activated carbon can adsorb from 5% to 30% of its own weight in organic solvent.

The capacity is due to the extremely large surface area of the carbon, with one pound having an area greater than 750,000 square feet!

Additional Information

One of the most effective methods of reducing the emission of solvent vapors is by capturing and recycling them through a carbon adsorption system.

A properly designed & sized carbon adsorption system can return 98% or more of the captured solvent vapors for reuse in the processing cycle. Since evaporation is the primary cause for solvent losses, this can mean reduction in solvent usage - and cost - of as much as 80% or more.

Carbon adsorption is based on the unique physical phenomenon that a solid will, under favorable conditions, attract and hold other materials to its surface. And the most effective adsorbent is granular activated carbon; elemental carbon which has been specially processed to improve its adsorbency and structural strength. Due to its non-polar surface, activated carbon will preferentially attract other non-polar materials such as organic solvents, rather than polar materials such as water.
