ABSTRACT:
A process and apparatus for recovering and treating hazardous and non-hazardous components from process streams generated from a continuous system for selectively separating organic and inorganic constituents from contaminated material. The contaminated material is heated in a dryer to a first temperature sufficient to volatilize water and lower boiling point constituents contained in the material, thereby producing a dried solid material and a first gas containing water vapor and volatilized lower boiling point constituents. The first gas is separated from the dried solid material. The lower boiling point constituents are recovered from the first gas. The dried solid material is heated in a desorber to a second temperature sufficient to volatilize higher boiling point constituents contained in the dried material, thereby producing a substantially decontaminated solid material and a second gas containing volatilized higher boiling point constituents. The second gas is separated from the substantially contaminated solid material, and the higher boiling point constituents are recovered from the second gas.
