Use of propulsion system to improve atmospheric dispersion in conducted emission sources in a fish oil processing plant

on .

   P48I3The technical recommendations in the design of stacks indicate that the emission at higher height, or a greater exhaust speed gases, decreases the impact in the surroundings. In fact, it is usual increases stack height in problematic sources.

   Taking into account this principle, additional propulsion systems for conducted sources have been designed. This type of technology allows to power the exhaust gases at a high speed, diluting simultaneously with a high flow rate, and minimizing the impact on the environment.

First results of a new Odour Citizen Science Project on Odours in Falconara, Italy.

on .

 Odornet ARPA  Odor.Net is a real-time monitoring project of olfactory nuissance in the city of Falconara, Italy, launched by ARPA Marche last June, carried out through the use of a simple APP for smartphones and tablets. After 7 months of work, some preliminaries result have been presented.

   The "Odor.net" project launched by ARPAM (Agenzia Regionale per la Protezione Ambientale delle Marche) in collaboration with the Region and the Municipality of Falconara Marittima, started on the 22nd of June 2019 and nowadays has 252 registered users on the territory (those who have downloaded the APP), which have reported 1.205 odour issues via this app. These results set up this project as one of the interesting citizen science projects relaed to odours launched in the last months.

Measurement of odorous compounds with a device based on SPRi Technology

on .

P11Ip   A device developed by Aryballe Technologies (Grenoble – France) and based on Surface Plasmon Resonance (SPR) imaging was used to measure odorous compounds. One advantages of such a device is to propose a large number of receptors inside the measurement cell.

   This aspect allows a distinction capability that cannot be obtained with classical instruments. Presented results show a strong capacity of distinction of compounds even isomers and a detection limit dependent on the family of compounds and the size of the molecule.
