State-of-the-art VOC abatement from soil-venting operations

The development of treatment technologies to limit the discharge of volatile organic compounds (VOCs) into the atmosphere has proceeded apace with the increasing use of soil venting for the remediation of contaminated soil. This article surveys the commonly-used emission control systems that have developed under air pollution control regulations in California. Emphasis is on equipment operating characteristics, typical performance results (destruction efficiencies of VOCs), and operating costs. A recently commercialized process for treating halogen-containing VOCs is described, and some operating and cost data are included.
