Abstract


The hereby paper deals with issues referring to the pollution of soils contaminated with crude oil and their improvement using the thermal desorption technology. Thus, the soil sampling area and the results of its properties analysis are described. According to the findings, the soil sample indicates an argillaceous texture. This sample was used in the laboratory with the purpose of pointing out the process parameters within the thermal desorption technology. The thermal desorption was accomplished in the drying oven at a temperature of 200 ºC. The periods of time for being hold in the drying oven were 10, 15 and 20 minutes. Through the results of this research it has been proved that the decontamination efficiency depends on the duration of the soil’s exposure to the temperature established in the decontamination process.
