ABSTRACT:
A high throughput apparatus and process for thermal remediation of soil contaminated with volatile organic compounds has a dryer with a high capacity heat source to volatilize and combust the compounds contained in a first lot of soil. The remediated soil is discharged and cooled. Hot gases and fines formed are drawn into a second dryer with an ignition source where a second lot of soil is used to cool the hot gases/fines mixture. A particulate control chamber is used to remove at least 75% of the fines from the gas/fines mixture. Gases containing uncombusted volatile organic compounds are directed back to the primary dryer for additional exposure to heat in order to complete combustion. Additional separation of the fines from gases is achieved in a baghouse.
