This Technical Analyses Report summarizes a Fluidized Bed Adsorption FBA performance test conducted under a Program Research and Development Announcement PRDA at McClellan Air Force Base McClellan AFB, Sacramento, California. This document presents the test objectives, test procedures, results, evaluation, conclusions, and recommendations. The FBA process involves cycling adsorbent resin beads through two chambers an adsorber and a desorber. In the adsorber, volatile organic compounds VOCs in the process gas are transferred onto the resin beads. In the desorber, the beads are heated to remove the adsorbed VOCs into nitrogen purge gas the nitrogen is then chilled to condense the VOCs into a liquid condensate suitable for recycling. FBA was identified as an innovative technology for testing at an existing soil vapor extraction SVE system at McClellan AFB Investigative Cluster 31 IC 31 Appendix A - Plate I a mixture of petroleum hydrocarbons and chlorinated VOCs is present in soil at this site. The original intent of the demonstration was to collect performance data to document FBA costs and treatment capabilities. However, site conditions adversely impacted FBA operations, and the scope and objectives of the demonstration were modified to assess how the mixed organic waste stream would affect the performance of the adsorbent resin beads.
