The circulating air barrier: Effective prevention of liquid contaminant movement through soil

PDF Version Also Available for Download.

Description

Objectives of this task included design, modeling, selection of drilling and surface processing equipment, and development of test procedures and cost estimates for conducting a cold test demonstration of the Circulating Air Barrier (CAB) process. The demonstration configuration is scaled to a prototype CAB system designed specifically for the C Tank Farm at the Hanford Site. The CAB system is designed to function as a containment barrier to prevent contamination of the water table located approximately 200 feet below the base of the C-Tank-Farm underground storage tanks. The CAB system is a desiccant-type barrier designed to prevent the migration of ... continued below

Description

Objectives of this task included design, modeling, selection of drilling and surface processing equipment, and development of test procedures and cost estimates for conducting a cold test demonstration of the Circulating Air Barrier (CAB) process. The demonstration configuration is scaled to a prototype CAB system designed specifically for the C Tank Farm at the Hanford Site. The CAB system is designed to function as a containment barrier to prevent contamination of the water table located approximately 200 feet below the base of the C-Tank-Farm underground storage tanks. The CAB system is a desiccant-type barrier designed to prevent the migration of liquid contaminants toward the ground water by using an air circulation and processing system to lower the saturation in a targeted subsurface zone below the saturation level required for liquid flow through that zone. The CAB system offers several important advantages, including the fact that it is a non-physical confinement technology, it has an active monitoring and leak detection capability, it is based on proven, commercially available equipment and oil and gas technologies; it has excellent potential for emergency response and rapid deployment; and offers high potential for integration with other remediation technologies. Demonstration- and full-scale CAB systems have been designed for the Hanford Site as part of this task.
