A fixed-bed catalytic oxidation system with caustic scrubbing was used to cost-effectively control emissions of aliphatic/aromatic and chlorinated hydrocarbons during soil remediation at McClellan Air Force Base (McAFB), Sacramento, California. Soil gas extracted by a soil vapor extraction (SVE) system contained trichloroethane (TCE), 1,1,1-trichloroethane (TCA), cis-1,2-dichloroethene (DCE), methylene chloride, and a variety of petroleum-based hydrocarbons. Catalytic oxidative treatment of these chlorinated hydrocarbons creates acid gases (hydrochloric acid [HCl] and hydrofluoric acid [HF]), which were removed in a caustic scrubber. Testing for hydrocarbon destruction and removal efficiency (DRE), acid gas scrubbing efficiency, dioxin/furan formation, and criteria pollutant emission rates (process byproducts) was conducted. Over 175,000 pounds of hydrocarbons have been treated/biodegraded in a nine-month operating period.
