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.

   A new miniaturized electronic nose (60x60 mm) connected to a smartphone through Bluetooth connection that was presented in this conference has an electronic design similar to other prototypes, but with a smaller size and consumption. The control of the system is based on a microcontroller PIC18F46K80. It includes four miniaturized MOX sensors and an integrated sensor of ambient temperature and humidity with suitable conditioning circuits.

   Communications with the smartphone are made using a Low Power Bluetooth Transmitter. An Android application has also been developed to connect to the device and to monitor the measurements. Data processing is performed remotely on a server by sending a request to it and subsequently receiving the output value of a classifier based on neural networks or fuzzy logic calculated on the server.
