Air Quality Enhancement/VOC Concentrator

Today’s ever-increasing environmental emission controls, including VOC control, demand an effective technical and economical solution to the issues facing spray paint booths (e.g., automotive), furniture, metal, electronics, printing, paper and other manufacturers.

To successfully meet the VOC effluent specification requirements, VOC abatement concentrator manufacturers choose ZEOflair adsorbents which offer the following key advantages over the traditionally used activated carbon adsorbents:

  • More hydrophobic at the typical higher relative humidity conditions
  • More efficient adsorption dynamic capacity due to stronger electrostatic energies
  • Adsorption capacity that is more resistant to the waste stream’s temperature fluctuations
  • More chemically and thermally inert adsorbent

Process Description

Solvent-laden air is drawn through the HoneyCombe rotor where VOCs are removed from the airstream by adsorption onto the hydrophobic (organophilic) zeolite. After passing through the rotor, the cleaned air is discharged into the atmosphere.

The Zeol rotor turns continuously, transporting adsorbed VOCs into a regeneration zone. There, the VOCs are removed by a small heated airstream that is 5–10% of the process air volume. The regenerated zeolite is then rotated back into the process airstream.

The concentrate is typically sent to a small oxidizer where the VOCs are converted to water vapor and CO2. The energy content of the VOCs contributes to the oxidation process, further reducing the fuel requirement.

Frequently Asked Questions

Yes, they are.

Excellent ZEOflair powder dispersion in the formula, choosing the correct ZEOflair powder type, and achieving the correct additivation (concentration) levels.

it depends on the size & concentration levels of odor/VOC compounds one tries to target for removal in the formulation. Type 100/110 for smaller size compounds, type 350 for medium size compounds, and type 800/810 for larger size compounds.

ZEOflair powders’ ability to remove odor/VOC compounds at elevated temperatures is diminished. However, as the material starts to cool down, the odor/VOC compounds that are still left in the formulation will be adsorbed by ZEOflair powders
