Abstract
Dielectric heating is used to assist with the cleaning of sorbent materials contaminated with oils and the like and the recovery of the solvent. In particular, a pressurized system is used such that a pressurized solvent is circulated to remove the contaminants from the sorbent materials. The RF radiation is directed into the vessel to vaporize residual solvents associated with the sorbent materials. Solvent is separated from the removed contaminants for reuse. RF radiation can be used to complete the removal of volatile compounds from the reclaimed oil/contaminants.
