Solvent Recovery & VOC Abatement Systems

Fluidized Bed Concentrator


Environmental C&C’s fluid bed VOC (volatile organic compound) control and solvent recovery systems provide proven, cost effective technology for industrial applications with high volume, low concentration flows of VOC's. This system can easily achieve flow volume reduction ratios of 1000:1 to as high as 10,000:1, allowing for several highly economical final treatment options. The high volume reduction translates into low capital and operating costs compared with standard concentrator systems, or direct treatment.

A proven technology, Environmental C&C’s fluid bed systems are currently treating exhaust streams at facilities for semiconductor manufacturing, painting/finishing, and printing.

Systems range in size from 200 cfm to over 100,000 cfm with final treatment being either condensation for solvent recovery, or thermal oxidation for VOC destruction. Removal or recovery rates of 95% - 99% are achievable. Because of the high turn-down ratio, these "back end" systems are significantly smaller than stand-alone systems, saving on capital expenditures.

How it Works

The adsorber section of the fluid bed 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 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.

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.
