Exhaust Air Concentration – Sustainable VOC Management at Scale
How It Works: Zeolite-Based Adsorption & Desorption
Our systems utilize hydrophobic, non-combustible zeolites to adsorb VOCs from high-volume air at low temperatures. Once saturated, these zeolites are regenerated using a smaller volume of heated desorption air, which:
- Reduces total exhaust air volume
- Increases VOC concentration significantly (up to a 1:50 ratio)
This elevated concentration allows the downstream thermal oxidation unit to operate autothermally, often without the need for additional fuel.
Integrated with Thermal Oxidation Systems
Following concentration, the desorption air—now rich in VOCs—is efficiently purified through:
- Reduces total exhaust air volume
- Increases VOC concentration significantly (up to a 1:50 ratio)
- Catalytic oxidation systems
For processes that demand simultaneous electricity and heat, integration with micro gas turbines offers an efficient and compact combined heat and power (CHP) solution.
Toward CO₂-Neutral Air Purification
When paired with an electrically heated catalytic oxidizer, this concentration-oxidation system can be operated entirely using renewable energy, eliminating the need for fossil fuels.
This makes it an ideal choice for industries pursuing carbon neutrality and sustainable operations while ensuring strict compliance with environmental regulations.
