VOC Treatment - Modular Equipment
VOC Concentrator Rotor
VOCs Concentrator Rotor (HAR)
Treating high-volume, low-concentration VOC exhaust streams typically requires large treatment equipment, which significantly increases both capital and operating costs.
By using a VOC Concentrator Rotor, a large volume of low-concentration VOC-laden exhaust can be concentrated into a much smaller air volume with a higher VOC concentration, enabling more efficient downstream VOC treatment.

Choices of Adsorption Media
- Match the adsorbent media to the emissions in the process
- Zeolite vrs. Carbon
– Complimentary Rather Than Competing Technologies
- Structural Differences
- Applications Differ
- Adsorption Characteristics Differ
Removal Efficiency relates how:
VOC is transferred from large air volumes to adsorbent media prior to exhausting to atmospher
How VOC Removal Is Achieved
VOCs are transferred from the high-volume process air to the adsorbent medium before the treated air is discharged to the atmosphere.
Concentration Technology
Concentrators are CAPTURE Devices
- VOC are removed from process air by adsorption
- Adsorption media is continuously regenerated
- VOC destruction after concentrator becomes very economical
Concentration Technology
The concentrator is a VOC capture device that removes VOCs from process air through adsorption. The adsorbent medium is continuously regenerated, allowing the captured VOCs to be released into a much smaller desorption air stream.
After concentration, downstream VOC destruction becomes significantly more economical and energy-efficient.
Suitable Applications for Concentrators
High air volume – low VOC concentration
VOC Concentration <800-900 ppm
- Process exhaust temperature <120°F
- No resin, heavy metals, or oils present
- No halogenated compounds present
- No sulfur compounds present

| ADSORBENT | WHAT IT ADSORBS |
| Carbon | Removes xylene and most common paint solvents. Ineffective at removing methanol. |
| Zeolite with 6Å pores | Removes methylene chloride, methanol and most low-molecular-weight solvents. Somewhat less effective with xylene and solvents larger than 6Å diameter. |
| Zeolite with 8Å pores | Removes higher-molecular-weight solvents. |
| Carbon and zeolite in a series | weight solvents. Removes solvent mixtures containing moderate amounts of methanol (15% to 25%) at low total VOC loadings (less than 250 ppm). Note that a physical mixture of carbon and zeo-lite on a single substrate is more effective than the two in series at removing high concentrations of solvents (>300 ppm) with lower (<20%) alcohol contents. |
