Thermal Desorption

Thermal desorption represents a “separation and ecological remediation process” that uses heat as an agent to remove contaminants from soils/sludges contaminated with hydrocarbons and/or other pollutants with volatile components.

This type of installation has a major advantage because it has a large soil treatment capacity. Hydrocarbons and/or other volatile components sustain combustion, improving the efficiency of the installation.

The thermal desorption installation is fully equipped with all measurement and control devices, thus enabling real-time monitoring and adjustment of treatment parameters.

These contaminated soils are treated at temperatures of 650 °C, and the soil maintains its physical properties.

The state-of-the-art monitoring system within this installation will control specific parameters for polluted soils, oil sludges, gases resulting from thermal treatment, and separated waters.

The results of Thermal Desorption

The contaminated soils with petroleum products have been treated, focusing on oil recovery. It can be observed that the result of treatment with the thermal desorption process is the inertization of the treated solid.
