The Anguil Emission Concentrator is an adsorption system designed to concentrate large volume, low concentration process exhaust into a much smaller, higher concentrated air stream.
The greatly reduced flow with higher Volatile Organic Compound (VOC) concentration is sent to a thermal or catalytic oxidizer for VOC destruction. The destruction device can then be much smaller in size, significantly reducing capital cost. The resultant higher VOC concentration controlled in the smaller abatement equipment minimizes auxiliary fuel consumption.

How Do Emission Concentrators Work?
The high volume, low concentration airstream passes through a rotor concentrator where VOC emissions are stripped from the air and adsorbed onto the zeolite. The majority (approximately 90-95% of the total air volume) of this clean air is then exhausted to atmosphere. A small portion of the air stream (approximately 5-10% of the total air volume) is heated to an elevated temperature to be used as desorption air.
The concentrator rotor spins continuously at a very slow rate, transporting adsorbed pollutants into a desorption section. In the desorption section, the VOCs are desorbed or released from the adsorptive media with the low volume heated airstream. This low volume, high VOC-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 coupled with a concentrator, an oxidizer will operate with little to no natural gas consumption. At higher concentration values, it even has sufficient “free energy” to provide desorption energy for the concentrator.

Rotor and Seal Service Options
Over time, exposure to process contaminants, temperature fluctuations, and normal operating conditions can impact rotor performance and VOC removal efficiency. For example, air seals play a vital role in maintaining proper separation between process, desorption, and cooling zones within a concentrator rotor. Worn or damaged seals can lead to air leakage, reduced concentration ratios, increased energy consumption, and lower VOC removal efficiency. Our experienced technicians can assess seal and wheel condition, recommend replacement intervals, and complete installation with minimal disruption to operations.
From performance assessments and planned maintenance to full wheel replacement projects, we help minimize downtime and restore system efficiency.
