Ex-Situ Thermal Desorption - Haemers Technologies

BIEN HOA – VIETNAM

During the US-Vietnam War, millions of liters of herbicides were dropped over Vietnam: The Rainbow agents. Agent Orange was proven to cause severe health issues, including birth defects, neurological problems and cancers. More than four decades after the Vietnam War ended (in 1975), the stability and bioaccumulation of dioxins - originating from agent orange - still affect the inhabitants. The Center for Technology Environmental Treatment/Chemical Force (CTET/CF), the GAET Corporation and HAEMERS Technologies SA agreed to establish a joint operation to...

STRASBOURG – FRANCE

This project was carried out under licence in collaboration with the company OGD – Ortec from October 2019 and June 2021. The contamination was due to the discharge of HAP and hydrocarbons (C>12). The soil came from various places along the canal (Citadelle Nord, Ouest and Sud, Starlette Nord and Sud). A thermal treatment platform was set up near the polluted soil, which was excavated and gradually brought to this platform. 41 Natural Gas Smart Burners – Reburn treatment (Vapor Treatment...

Saint-Nazaire – France

This site was part of a rehabilitation project in an urban area of the city of Saint-Nazaire (France). The contamination of the site was presumably caused by the previous activities of a gas plant. Two ESTD piles (respectively 1.500m³ and 2000m³ of soil) were built to treat the contaminated soil. 75 Gas Fired burners with the reburn technology.

Grønnedal – Greenland

The site is the former Grønnedal military base in Greenland. Three types of hydrocarbon contaminant were considered for the remediation: one was contaminated with C6-C15 hydrocarbons (helicopter fuel), the second one was contaminated with C10-C20 hydrocarbons (diesel fuel) and the third one was contaminated with C20-C35 hydrocarbons (heavy fuel/oil). In order to treat the tree types of contaminants, it had been decided to build a container made with sheet piles. The volume was divi- ded in 3 parts to treat...

Noroxo – France

The whole Noroxo site covered about 34 hectares. It was located between a commercial area and an agricultural area. In order to build the stockpiles (ESTD), 7.566 m² located at the extreme North West of the site were allocated for the thermal treatment. As the site contained explosive ordnance from WW1, a UXO clearance was performed prior and during all excavation works. Residual explosives were treated with the soil (ESTD) after ordnance removal. The main issue with high concentrated spots on a...

Xinxin – China

The site is located in the Province of Gansu in People’s Republic of China, near the town of Qingyang. The treatment zone is in an industrial area. The contaminated soils come from various sites in the region. The project is setup in a hangar on a surface of about 250m² with 9 diesel burners and a vapor treatment unit. The treatment area is impacted with various solvents. The targeted concentration at the end of the treatment is 3000 mg/kg. The treatment...

Kinkasi – DRC

The project took place in Kinkasi, Democratic Republic of Congo, on the site of an oil tanker Industrial. The floors were impacted by crude oil to average concentrations of 15,000 mg / kg. Grit treatment impacted by the hydrocarbons was performed with Smart Burners Technology, developed by Haemers Technologies. In first phase, a pilot was carried out on site in July/August 2012. It preceded the execution of the full scale which begins in late February 2013 and will involve the treatment...
