Abstract
An improved process and apparatus for treating particulate soil composition to remove volatilizable organic materials therefrom comprises separating fine particles of the soil from a gaseous mixture in a drum containing the fine particles and volatilized organic material, directing the separated fine particle heat exchange apparatus, indirectly heating the fine particles therein with hot exhaust gas to volatilize organic materials, and recovering the fine particles. The hot exhaust gas for heating the fine particles in the heat exchange apparatus is obtained from a furnace used to combust volatilized organic material.
