Performance Characteristics of a Multi-Stage Process for Ex-situ Treatment ofSolids or Liquids Contaminated with Chlorinated Organics

摘要

The U.S. Environmental Protection Agency has sought to develop soildecontamination technologies which are effective, but which do not involve incineration. This paper presents the results of a study in which a steam-assisted, thermodesorption system utilized on Guam was characterized in terms of its effectiveness for removing PCBs and PCDD/Fs from soil. Data are also presented which are indicative of the performance of the air pollution control system which is directly coupled to the thermodesorber. The potential for formation of PCDD/Fs during thermodesorption is discussed.
