Abstract
The article presents the development of a mathematical model concerning thermal desorption in a tubular electric furnace, using
the linear regression analysis principle. With a range of experimental data obtained from some laboratory tests on water
evaporation plus pollutant (Hexaclorocyclohexane - HCH), evaporation resulting from the application of thermal desorption on
some soil samples; a mathematical model was developed to calculate the mass of substance evaporated from the soil according to
the two important parameters of the process, namely the temperature (T) and the duration of maintenance (τ) in the furnace. By
numerical simulation, for values of temperature (T) of: 200 oC, 350 oC, 500 oC, 650 oC and maintenance time (τ) of 5, 10, 15 and
20 minutes, it was calculated the mass of evaporated substance. To validate the experimental model, the reproducibility
dispersion of results and the concordance dispersion were calculated. Results show that there is a good concordance between the
experimental data and data calculated using the mathematical model.
