Direct Fired Thermal Desorption

Product Details

Using the process of Direct Fired Thermal Desorption or also commonly referred to as Low-Temperature Desorption, Nelson Environmental Remediation offers on-site extraction and destruction of toxic organic compounds to produce, as their slogan says – “Clean Dirt, No Doubt!”.

Low-Temperature Desorption removes organic contaminants from soil, sludge or sediment by heating them in a machine called a “thermal desorber” to evaporate the contaminants. The evaporation process volatilizes the organic contaminants in the soil into a vapour phase (gases) which in turn, separates them from the solid material. The process is not a form of incineration and is defined by the Environmental Protection Agency (EPA) as “a physical separation process”. The volatilized vapours pass through a baghouse filtration system then into a thermal oxidizer and are oxidized into CO2 and water.
