Thermal oxidizers are used to destroy volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from expelled industrial air streams. The waste gas is almost entirely burned off using incredibly high temperatures. The hydrocarbon-based pollutants are converted to water and released as vapor.
Catalytic oxidizers, also known as catalytic incinerators, work similarly to thermal oxidizers in purpose but use a catalyst to produce the oxidation. This oxidation process utilizes precious metals within the oxidation system that promote the breakdown of VOCs. Catalytic oxidizers have the advantage of operating at much lower temperatures than thermal oxidizers.
Wet scrubbers work by bringing the polluted gas into contact with a scrubbing liquid. Web scrubbers have the advantage of being able to collect particulate matter as well as gaseous pollutants. In addition, they work well under high temperatures, have a smaller footprint than other air pollution control system options, and work well at neutralizing corrosive gasses.
Regardless of the air pollution control system in place or planned for installation they all inevitably utilize a comprehensive system of industrial ductwork. The planning for the ductwork usually requires strict sizing and material constraints. E+E Group has an extensive engineering background that allows us to tackle industrial ductwork projects of all sizes with precision.
ENERGY AND HEAT RECOVERY SYSTEMS
All industrial air pollution control systems utilize a great deal of energy in one form or another. The ability to recoup that output of energy via heat recovery leads to enormous savings in energy costs. E+E Group engineers are experts at evaluating individual industrial oven and reactor solutions for possible heat recovery solutions.
SELECTIVE CATALYTIC REDUCTION (NOX ABATEMENT)
Selective Catalytic Reduction (SCR) is a means of converting nitrogen oxides (NOx) into diatomic nitrogen and water using a catalyst. Commercial SCR systems are used to reduce pollutants found in industrial boilers, gas turbines, and larger scale diesel engines. The effective reduction of NOx in such systems can be as high as 95%.
Heat exchanges processes between multiple industrial systems can be an enormous cost to a company if they are not engineered to perform efficiently. Industrial heat exchange systems properly designed can not only perform at minimal cost but through utilization of recovery systems can reduce the cost of other subsystems as well. E+E Group engineers specialize in industrial heat exchange and recovery systems that perform with a high degree of efficiency.
