Our achievements

The application aims to carry out the depollution of the ground charged in hydrocarbon and in HAM (Monocyclic Aromatic Hydrocarbon). The pollution is noted on a depth of about 22 meters. The principle used for the depollution under this depth is to extract air charged with pollutant via wells put in depressive line. The air loaded with pollutants is then treated on a bed of activated carbon and dispersed via a discharge stack.

Design and realization by exelio of two mobile air extraction installations under container. The gas turbine has a variable flow rate. The application is zoned and realized according to the ATEX standards.

A PLC ensures the fully automatic operation of the system and remote management. An operator’s panel allows an instant visualization of the operating values, the visualization of the curves of these values and the easy adjustment of the driving parameters.
