US Patent:

20020128782, Sep 12, 2002

Filed:

Jan 8, 2001

Appl. No.:

09/756550

Inventors:

Walter Weber - Ann Arbor MI, US
Martin Johnson - Dunbar WV, US

International Classification:

G06F019/00

US Classification:

702/032000

Abstract:

A laboratory technique for rapidly predicting the long-term hydrophobic organic contaminant (HOC) desorption behavior in a contaminated soil or sediment useful for planning remediation schemes and/or assessing alternative remediation endpoint decisions employs a superheated water extraction technique for rapid prediction of long-term HOC desorption. The proposed method has great practical significance because desorption at ambient temperatures requires months or years, while high temperature experiments are accomplished in hours or days.

Abstract:

Toxic and hazardous organic materials are photochemically and thermally changed into innocuous and environmentally acceptable products through the proper application of solar energy. The present invention is especially well-suited for the destruction of polychlorinated biphenyls (PCB's) which are resistant to conventional incineration The method and apparatus described herein are also capable of handling liquids, solids or vapors, with only minor operating modifications.
