THERMAL DESORPTION WITH SMART BURNERS: CASE STUDY FOR THE IN SITU TREATMENT OF UNSATURATED SOILS AT THE REFINERY OF GELA (ITALY)
Pacella, K., J. Haemers, and H. Saadaoui.
15th International AquaConSoil Conference: Sustainable Use and Management of Soil, Sediment and Water Resources, 20-24 May, Antwerp, Belgium, 2019
A pilot-scale study tested a new thermal desorption technology on contaminated soils within the Refinery of Gela in Gela, Italy. The site is contaminated with light and heavy hydrocarbons, benzene, PAHs, chlorinated compounds, and mercury. The thermal desorption technology heats contaminated soil using Smart Burners to reach an evaporation point, where the volatile contaminants are aspirated through perforated extraction pipes. During the pilot test, 143 burners were installed and positioned on top of steel pipes. Treatment was complete when reaching a temperature of 200°C at the cold points for 20 days or 250°C for 3 days. Results showed the complete removal of contaminants in the soil matrix after sustained treatment at the target temperature, allowing for maximum extraction of vapors.
