APA SYSTEM • Multifunction modular platform • Innovative technology • Abatement with high efficiency of: • particulate matter • heavy metals • PAHs – polycyclic aromatic hydrocarbons • hydrocarbons (methane, benzene, etc.) • NOx, SOx and CO2 • Air flow: 1.350 – 2.350 m3/h • Volume 0.5 – 3 m3 • Low power need: 550 W RESULTS: CLOSED WORKING AREA OF AN INDUSTRIAL PLANT • Fiberglass industrial plant • Principal Emissions: Particulate and Hydrocarbons (CnHm) • N° 2 APA systems • Optical Particle Counter and CnHm sensor RESULTS: BOLZANO EXPERIMENT LABORATORY TESTS - NO and NO2 APA Bolzano APA reduces the particulate and Hydrocarbons concentration Layout of the experiment Factor of reduction per cycle Particulate Hydrocarbons (CnHm) Concentration Distance 1.5 km BZ5 Air quality Monitor station Piazza Adriano BZ5 Air quality Monitor Station Via Claudia Augusta BZ4 Air quality Monitor Station APA system present APA system NOT present Initial Concentration Cycle period APA effect is evident by comparison NO2 concentration measured at the two site • PERIODS OF AVERAGING • APA off: Jan 17-23 2013 • APA on: Jan 24 – Feb 20 2013 • APA off: Feb 21 – Mar 31 2013 First test: NO and NO2 Preliminary Results Comparison between Daily behavior (10 days average) of CnHm concentration: APA active (blue points-8:00-19:00 ) , APA not active (red points) APA system action is effective over all the classes of sampling. The efficacy increases with the size of particles Abatement factor APA on Gas sample injection APA Start APA reduces the average NO2 concentration at the BZ5 site, increasing the difference APA abatement efficacy on the particulate concentration APA off APA off FNO = 4 % per cycle Before and after the “APA on” period they are comparable within the error bar FNO2 = 6 %
