TKS Industrial offers VOC Concentrators for air pollution control on paint booth exhausts.
The VOC Concentrator is an activated carbon or zeolite adsorption system designed to capture and destroy volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from industrial process exhausts.
A concentrator system consists of three main phases: Adsorbing, where the VOCs are captured; Desorbing, where the VOCs are heated and released; and thermal oxidation, where the VOCs are destroyed. The Adsorber and Desorber skid are show at right or below.Learn more on Wikipedia
A VOC Concentrator system consists of three main pieces of equipment and three primary process steps:
A heat exchanger is used to recovery waste heat from the thermal oxidizer and heat the fresh air coming in to the desorber. An optional heat exchanger can be used to use the incinerator's waste heat to warm the air coming into the oxidizer, making the thermal oxidizer into a recuperative thermal oxidizer.
The key feature of the VOC Concentrator technology is a smaller thermal oxidizer, saving energy costs.
Up to 80% reduction in natural gas usage, when compared to an RTO, and up to 65% reduction in electricity, depending on inlet conditions.
Up to 80% reduction in CO2 emissions from the thermal oxidizer burner. An ultra-low NOX burner controller is available also.
An VOC Concentrator system needs a smaller thermal oxidizer than a traditional RTO, Regenerative Catalytic Oxidizer (RCO), or Rotor Concentrator. A smaller thermal oxidizer costs less, reducing the required capital investment and saving you money upfront.
VOC Concentrator systems are used in the paint booth, coatings, semiconductor, electronics, materials, food processing, furniture, printing, and solvent recovery industries.
Our VOC Concentrator system works best for industrial exhausts containing airborne & gaseous organic solvents, VOCs, HAPs, and other volatile organics. Inorganic waste gases such as H2S, ammonia, and acid gases are a better fit for a gas scrubber.
VOC Concentrator doesn't work with exhaust temps above 120°F, exhausts containing alcohols with low boiling points or long-chain organics with high boiling points. Customers should also avoid non-volatiles and compounds prone to polymerization or joining reactions with other exhaust chemicals.
Unlike a traditional rotor concentrator that is limited to a 20:1 concentration ratio, the VOC Concentrator system and achieve concentration ratios in the hundreds if air is used as the desorption flow gas or the thousands if pure nitrogen is used as the desorption flow gas.
When replacing a large RTO system, an VOC Concentrator system can offer a reduction in energy usage up to 90%, depending on the size of the equipment. One customer successfully achieved an 80% reduction in energy usage when switching from a 100,000 cfm RTO system to a 100,000 cfm dual-Adsorber VOC Concentrator system at their Alabama plant.
Most batches of carbon last about one year, but it does vary some based on the solvent loading, total run time, and type of solvents, particularly the percentage high boiling point solvents.
Smaller VOC Concentrator systems can fit in a 25' x 25' area, but medium-to-large VOC Concentrators require a 30' x 30' area.
The VOC Concentrator system has been installed over 10 times since introduction at four different Fortune 500 companies.
