A Study on the Thermal Desorption Process of Oil-Contaminated Soil by Microwave

Abstract:

The objective of this study is to investigate and evaluate the thermal desorption process to treat soil contaminated with high concentration of oil by applying microwave and high temperature heating element. It was found that TPH (Total Petroleum Hydrocarbon) was achieved below 2,000 mgkg^-1 of Korea criterion at 8kW of microwave powder and 700°C of processing temperature for 20 minutes. In addition, the rate of thermal desorption was also the highest value to be 0.09711 at 8kW of microwave powder and 700°C of processing temperature. Compared to other cases, the thermal desorption process applied by microwave had faster desorption rate of oil than conventional heat treatment process indicating that it would shorten processing time to treat oil-contaminated soil.
