Description:
The U.S. Environmental Protection Agency recently funded a study which addresses the treatment of soils contaminated by petroleum hydrocarbons using low temperature thermal desorption (LTTD). he proposed paper will summarize some of the results of that study. TTD has become a major petroleum contaminated soil remediation technology. The paper will define LTTD and discuss fundamental thermal desorption mechanisms such as hydrocarbon vapor pressure, steam stripping and soil characteristics. ull-scale LTTD equipment such as asphalt kilns, rotary dryers, thermal screws and indirect fired calciners will be described. ypical off-gas treatment equipment such as afterburners, baghouses, wet scrubbers, carbon and condensation/recovery will also be discussed. ull-scale LTD performance data, such as hydrocarbon destruction efficiency, carbon monoxide and particulate stack concentrations, and soil total petroleum hydrocarbon residuals will be summarized.
