TKS Industrial offers an innovative carbon concentrator design called a
Fluidized Bed Cencentrator (FBC).
The VOC Concentrator, or FBC, is an activated carbon adsorption system designed to capture and destroy volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from industrial process exhausts.
An FBC system consists of three main pieces of equipment: the Adsorber, where the VOCs are captured; the Desorber, where the VOCs are heated and released; and the Thermal Oxidizer, where the VOCs are destroyed. The Adsorber and Desorber skid are show at right or below.Learn more on Wikipedia
An FBC 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 incinerator into a thermal recuperative oxidizer.
Currently in use at:
The key feature of the FBC technology is a smaller thermal oxidizer, saving energy costs.
Up to 80% reduction in natural gas usage, when comapred 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 / incinerator burner. An ultra-low NOX burner controller is available also.
An FBC 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.
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.
FBC 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 FBC 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 FBC system can offer a reduction in energy usage up to 90%, depending on the size of the equipment. Honda Alabama successfully achieved an 80% reduction in energy usage when switching from a 100,000 cfm RTO system to a 100,000 cfm dual-Adsorber FBC system at their Lincoln, AL 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 FBC systems can fit in a 25' x 25' area, but medium-to-large FBCs require a 30' x 30' area.
The FBC system has been installed over 10 times since introduction at four different Fortune 500 companies.
