Abstract: European Directives are coming into force setting increasingly stringent Emission Limit Values (ELVs) for key air pollutants to mitigate ~400 000 premature deaths and €330-€949 billion p.a. of costs attributable to air pollution. However, the emissions industry faces an issue as a metrologically robust framework of standardised measurement methods to enforce these directives is not fully in place. This project will address this measurement gap by innovating measurement methods for new measurands (NH3, formaldehyde, HF, PM, SVOC, OGC, PAH), address a lack of uncertainty characterisation in flow measurements and develop next generation techniques for increasingly stringent future legislation.
Two measurement campaigns were carried out. The first one, at INERIS (F), verified the stability of different optical detection techniques versus the composition of the exhaust gases. For the first time, a multipass cell was deployed directly inside a stack, at the temperature of 140 °C. The second campaign, at ISSI Innovhub (MI), verified the effect of turbulence on the propagation of the exhaust gases, by measuring the concentration of a tracer gas in different points of the stack.
