Abstract
An apparatus and method for remediating soils and other materials contaminated with organic compounds comprising dual volatilizing zones and radiant heat. The material is treated in the volatilizing zones to substantially volatilize the organic compounds contained within the material.
Claims32
An apparatus for heating material which is comprised of:
- a rotary cylindrical drum, having first, second and third concentric cylinders of decreasing diameters;
- means to introduce said material into said drum, such that said material is introduced into one of said first and third cylinders;
- a heating means interacting with said second cylinder to create an atmosphere in said first and third cylinders which will heat said materials required;
- transporting means for transporting said material along a length of said first and third cylinders;
- a transfer means to transfer said material from said one to the other of said first and said third cylinders;
- and
- an exhaust means to substantially ventilate gases evolved from said material away from said material as said gases are evolved.

A method of heating material comprises the steps of:
- rotating a cylindrical drum having first, second and third concentric cylinders of decreasing diameters;
- conveying said material into one of said first and third cylinders;
- radiantly heating said one of said first and third cylinders;
- radiantly heating said other of said first and third cylinders to further heat said material;
- traversing said material along the length of said other of said cylinders;
- and
- discharging said material.

4 more elements
A method of remediating material in order to substantially volatilize compounds contained within said material comprised in the steps of:
- rotating a cylindrical drum having first, second and third concentric cylinders of decreasing diameters;
- conveying said material into said first cylinder;
- radiantly heating said first cylinder to create an atmosphere that will substantially volatilize water and some of the organic compounds contained within said material;
- traversing said material along the length of said first cylinder;
- transporting said material to said third cylinder;
- radiantly heating said third cylinder to create an atmosphere that will volatilize substantially all the organic compounds contained in said material;
- traversing said material along the length of said third cylinder;
- and
- discharging said material.
