    摘要: 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.

    摘要: The present invention relates to a method for separating chemical contaminants such as volatile and semi-volatile chemicals and polychlorinated biphenyls (PCBs), even if the contaminants are present at low concentrations, from mixed wastes, such as soils or sludges contaminated with hazardous and radioactive components. The process comprises subjecting the mixed waste 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 the volatile and semi-volatile contaminants. The evolved vapors may be collected and condensed for off-site disposal and the remaining solids may be properly disposed of or further treated.
