ABSTRACT:
A method for economically separating chemical contaminants such as volatile and semivolatile organic chemicals and polychlorinated biphenyls (PCBs), even if the contaminants are present at low concentrations, from inert materials such as soils or sludges is disclosed. The process comprises subjecting inert materials contaminated with chemical compounds to vacuum at a temperature effective to volatilize the contaminants but below incineration temperature, while continuously removing the evolved vapors, for a period of time sufficient to effect the desired degree of separation of contaminants. The evolved vapors may be collected and condensed for off-site disposal.
