Fluidized Bed Concentrator (FBC) Environmental Control Technology

How it Works

The adsorber section of the fluidized bed concentrator system includes a series of perforated plate adsorption trays. Contaminated process exhaust enters from the bottom, passing upward through the adsorption trays, fluidizing the adsorbent and adsorbing the Volatile Organic Compounds (VOCs). VOC saturated adsorbent flows to the bottom of the adsorber vessel, from which it is removed at a slow, steady rate and transferred to the desorber. Meanwhile, regenerated adsorbent is continuously fed into the top of the adsorber vessel, providing counter-current VOC removal.

In the desorber, the temperature of the adsorbent material is increased, causing it to release the VOC contaminants into a low volume, inert carrier gas stream. The cleaned adsorbent material is then returned to the top of the adsorber vessel for reuse.

The concentrated contaminant stream is so small that it can often be easily treated with a simple afterburner or recovered for reuse or disposal through condensation. The condensation process is shown below.

One key to achieving high performance levels is the beaded activated carbon adsorbent material. The small, spherical “beads” have a high surface area for adsorption and are ideal for treating a wide range of solvents at high or high concentrations. With an attrition rate of less than 1% per year, operating and maintenance costs are extremely low.
