Abstract

   For the industrial sector, in many occasions it is the directed sources that are the main route of emission of pollutants into the atmosphere. In these cases, the technical recommendations for minimizing the impact of industrial emissions on the environment indicate the chanelling of these emissions for dispersion at some height as a first step towards establishing possible corrective measures.

   The emission of these pollutants at a higher altitude, or with a higher gas exit velocity at the focus, minimizes the impact on the environment. Using this principle as a basis, additional propulsion systems have been designed for directed sources. This propulsion is achieved by installing a turbine on the upper exterior of the chimney. In this study, the Calpuff atmospheric dispersion model was used for the evaluation of the improvement in the environmental quality obtained in the surroundings of a chemical industry installation, from the installation of three Eolage (Delamet) propulsion systems, on three chimneys.

   The gases emitted by these chimneys were characterized by a major odoriferous impact due to the high concentration of hydrogen sulphide. The installed Eolage systems propel the exhaust gases through the chimney at a speed of 30 m/s with a flow rate of 120.000 m3/h. By means of the atmospheric dispersion model, it was possible to verify that the installation of these systems would produce a reduction of the impact of the hydrogen sulphide, thus reducing the odoriferous pollution present in the surrounding environment.
