Rotary Concentrator-VOC Emission Control

Rotary Concentrator Systems from The CMM Group are hybrid VOC abatement systems designed to efficiently remove and destroy volatile organic compound emissions from a process exhaust air stream. The polluted air passes through a rotating wheel where the air pollutants are adsorbed onto a hydrophobic Zeolite media and then removed and destroyed by use of an oxidizer.

During operation, air pollutants, captured from the process via a ductwork collection system, are passed through a high-efficiency filter as particulate can damage the concentrator wheel media. Once filtered, the polluted air passes through the rotating concentrator wheel where the air pollutants are adsorbed onto the hydrophobic Zeolite media. A slipstream of this air, approximately 10%, is routed through a cooling plenum while the remainder is routed directly to the common exhaust stack.

The rotor itself is fabricated from a corrugated mineral fiber substrate to which the manufacturer permanently bonds a proprietary mixture of hydrophobic Zeolite and inorganic materials. The hydrophobic Zeolite rotor concentrator wheel is inorganic and completely inert, has rigidity, physical integrity and the ability to withstand thermal stress. In this application the Zeolite removes the air pollutant from the manufacturing process exhaust air stream as it passes through the rotor.
