In Situ Thermal Desorption under a building, in the center of Brussels

Nowadays, urban soil is a natural ressource to preserve. Indeed, the fast urbanization of the recent years led to considerable consequences in terms of space and energy consumption as well as water and soil pollution. At the present time, urban areas contain many contaminated sites. Two main issues can be identified which would need to be addressed through further reflection: first, the space consumption. Polluted areas in the centre of the cities are a waste of space. The clean-up of [...]

Laboratory tests and pilot conception at Biên Hòa Airbase, Vietnam

During the US-Vietnam War, millions of litres of herbicides were dropped over Vietnam: The Rainbow agents. Biên Hòa Airbase was a joint operating base for the South Vietnam Air Force and the United States Air Force where thousands of barrels of Agent Orange were stored. Agent Orange was proven to cause severe health issues, including birth defects, neurological problems and cancers. Agent Orange is a mixture of 2,4-dichlorophenoxyacetic acid and 2,4,5-trichlorophenoxyacetic. Traces of dioxins were also found in some Agents. [...]

Thermal Conductive Heating (TCH): electrical resistance heating or gas fired burners

Thermal desorption is an environmental remediation technology that uses heat to increase the volatility of contaminants (organic and/or inorganic) as such that they can be removed from solid matrix (typically soil) to be recycled or destroyed. The subject will focus on two existing in situ TCH techniques: electrical and thermal heating. The designs and calculations are made considering the injection of power per linear meter of heating element. The method of heat injection with electrical power directly injects 1 kW/m, [...]

Thermal Desorption of Highly-impacted mercury soils in an Urban Area

By Q. Hilbert, A. Vandekerckhove, H. SAADAOUI, J. HAEMERS - HAEMERS Technologies J. Chibleur, J. Leplat - Biogénie In-Situ and Ex-Situ Thermal Desorption (ISTD and ESTD) are a technology based on thermal conduction that can effectively treat organic contaminants, independently of large soil heterogeneity. One of its applications is for contaminated properties in urban areas and under existing buildings. The main principle of the technology resides in installing a network of steel pipes that act as a air/soil heat exchanger to heat [...]

Perfluoroalkyl and polyfluoroalkyl substances in the environment: Origins and feasibility in thermal desorption

Per- and polyfluoroalkyl substances (PFAS) came into use in 1950’s and since then have been used in numerous industrial and commercial applications. PFAS comprises a large group of compounds (> 6.000) consisting of at least a hydrophobic alkyl chain of varying length . This hydrophobic variety can be completely fluorinated (perfluorinated alkyl substances) or partly fluorinated with at least two fully fluorinated carbons (polyfluorinated alkyl substances). Compared to the binding energy of C-C bond (347 kJ/mol), the C-F bond (439 [...]
