ABSTRACT:
A method and system for removing volatile organic compounds (VOCs) from sludge advantageously utilizes a stripper for removing the VOCs directly from the sludge to convert the sludge into a non-hazardous material. Preliminary steps of mixing may include addition of a liquid to improve flowability. Then the sludge is moved through the stripper in which the VOCs are carried away in a gas provided in the stripper for the purpose of carrying the VOCs away. Any of a variety of strippers may be utilized for VOC removal. Subsequently, the liquid is separated from the sludge material in, for example, a dewaterer, and each of the liquid and the sludge is either recycled or dumped as a non-hazardous material or waste. The system may be configured in a variety of ways and still function properly in carrying out the method of the invention.
