Atmospheric impact assessment: regulatory purposes and real time, by Armand ALBERGEL (ARIA TECHNOLOGIES)


“Air quality on-line supervision system for industrial sites
Air quality around industrial sites is a more and more sensitive issue for industrial managers, especially due to new legal and environmental constraints. ARIA Technologies has developed a reliable and powerful supervision system, called ARIA View. It enables to follow the air quality around the site continuously, in order to get a complete and accurate understanding of the impact of industrial activity on its atmospheric environment. Industrial managers can also use ARIA View to prepare and produce the air quality reporting required by the administration. The system can deal with conventional pollutants, such as SO2, NOx, PM, CO/CO2, Dioxin, as well as new parameters (odors, legionella, hot air plumes, etc). Thanks to this system, production managers can predict the future air quality on site, depending on meteorological conditions and emissions. This prediction capability allows them to react accordingly as well as to plan non routine operations in advance. This key feature is based on powerful real-time and predictive dispersion modeling softwares Thus ARIA View can be considered as a true on-line air quality management system. On-line atmospheric impact of the plant uses the actual emissions values directly measured by a CEMS (stack monitoring) or computed by a PEMS (with the process data).”
