Zeolite Rotary Concentrator

Do you need to remove volatile organic compounds (VOCs) efficiently from large air volumes with low pollutant concentrations? Our Zeolite Rotary Concentrator is an innovative solution that concentrates VOCs before their subsequent removal, increasing exhaust-air treatment efficiency and reducing operating costs.

How the Zeolite Rotary Concentrator works:

Exhaust air is passed through a rotating zeolite rotor. In the first section of the rotor, VOCs are adsorbed onto a hydrophobic zeolite adsorbent that efficiently captures pollutants from the air stream. In a subsequent section, the captured VOCs are desorbed by a small stream of heated air. This concentrates the VOCs into a smaller air volume with a higher pollutant concentration, which is then routed to a suitable thermal treatment system. The process allows large air volumes with low VOC concentrations to be concentrated efficiently.

What is a Zeolite Rotary Concentrator, and how does it work?

A Zeolite Rotary Concentrator is designed to remove volatile organic compounds (VOCs) efficiently from exhaust air. It works by adsorbing VOCs onto a hydrophobic zeolite adsorbent in the rotor. Heated air then releases the captured VOCs into a smaller air volume, making their subsequent removal easier and more efficient.

Why is this system suitable for large air volumes with low VOC concentrations?

It can efficiently concentrate VOCs from large air volumes with low pollutant concentrations. This allows downstream thermal treatment systems to be smaller and more energy-efficient, resulting in lower operating costs.

What are the benefits of using a zeolite adsorbent?

The zeolite adsorbent is hydrophobic, so humidity in the air has little effect on it. Its high VOC capture capacity and long service life improve the system’s overall efficiency and reliability.

How often must the zeolite adsorbent be replaced or regenerated?

The zeolite rotor is designed for continuous operation with automatic regeneration. The adsorbent is continuously regenerated as the rotor turns, so regular replacement is not required, reducing maintenance costs.

How does this system help protect the environment?

By removing more than 98% of VOCs from exhaust air, it reduces harmful emissions into the atmosphere. The system’s low pressure drop and high concentration factor also improve energy efficiency and reduce the operation’s overall environmental footprint.
