Typical air pollution control projects focus on the capture mechanism and a destruction device.  With regulations driving towards higher capture efficiencies, combustion devices must treat larger volumes of air with lower concentration of pollutants. 

The Anguil concentrator is an adsorption system designed to concentrate large volume, low concentration process exhaust into a much smaller, highly concentrated air stream. The greatly reduced flow is rich in emissions when sent to a thermal or catalytic oxidizer.  The destruction device can then be much smaller in size and utilizes the steady stream of emissions to fuel combustion of incoming contaminants.

Typical applications include but are not limited to large paint systems, Permanent Total Enclosure (PTE) exhaust and styrene emissions.

How the Emission Concentrator Works

The high volume, low concentration airstream passes through a rotor wheel or cartridge style concentrator where emissions are stripped from the air and adsorbed onto the substrate. The majority (approximately 90% of the total air volume) of this clean air is then exhausted to atmosphere. A small portion of the air stream (approximately 10% of the total air volume) is heated to an elevated temperature to be used as desorption air.

The concentrator rotates continuously, transporting adsorbed toxins into a desorption section. In the desorption section, the organics are desorbed from the adsorptive media with the low volume heated airstream. This low volume, high emission-laden air is then processed by an oxidizer.

The concentrator with integrated oxidizer is often the most cost effective technology for processing high volume, low concentration streams. While the capital cost of a system is competitive with other technologies, the true savings is realized in reduced operating costs.  When couple with a concentrator, an oxidizer will operate with very little additional natural gas consumption.  At higher concentration values, it even has sufficient "free energy" to provide adsorption energy for the concentrator.
