Impact work package leader Tuula Pellikka (VTT) took the attendees through an introduction to the project, and this was followed by presentations on The comparability of the analytical quantification step of EN 1911 –total chlorides, presented by Alice Hirons (NPL); Uncertainties calculated for EN 1911, provided by the participants during ILC organized in France (by INERIS) presented by Tuula Kajolinna (VTT); Some uncertainty sources in isokinetic sampling presented by Jan Geršl (CMI); Laboratory tests for different impinger types presented by Tuula Kajolinna and Observations from the field test organised in Finland, performance of EN 1911 and P-AMS (FTIR) presented Tuula Pellikka. Twenty-two people attended the workshop, those participating were from across Europe and include regulators from various regional state administrative agencies, plant owners, analyser manufacturers and stack testing teams. 08.02.2022 Inter-Laboratory Comparison work at NPL Illustrated above is some of the NPL Teddington Stack Simulator Inter-Laboratory Comparison work at NPL under WP1, Task 1.2. The aim of this task is to extend European stack simulator facilities to generate emissions data under controlled real-world conditions, applicable to industries regulated via BAT Conclusions documents for the existing HCl SRM (on the INERIS Stack Simulator facility) and also for portable optical technologies (on the NPL Stack Simulator facility). You can find out more about WP1 here. 14.01.2022 Successful M27 Project Meeting for HEROES A successful M27 meeting for the HEROES project was held online earlier this week. Project Co-Ordinator Marc Coleman (NPL) took the stakeholders through an introduction to the project, and this was followed by presentations on WP1 by Isaline Fraboulet (INERIS); WP2 by Marc Coleman (NPL) and WP3 by Tuula Pellikka (VTT) with much discussion on the work progressed during the presentations. 14.12.2022 Inter-Laboratory Comparison work at INERIS Illustrated above is some of the Stack Simulator Inter-Laboratory Comparison work at INERIS under WP1, Task 1.2. The aim of this task is: to extend European stack simulator facilities to generate emissions matrices containing HCl under controlled real-world conditions, applicable to industries regulated via BAT Conclusions documents. to evaluate the suitability of measurement methods for monitoring HCl: for the existing HCl SRM (on the INERIS Stack Simulator facility) and also for portable optical technologies (on the NPL Stack Simulator facility). You can find out more about WP1 here. 22.11.2021 HEROES FTIR Measurement Field Work With VTT In April 2021, VTT set up HCl-concentrations, mg/m3(n), measured with two EN 1911 sampling lines, two PAMS-FTIRs and a CEMS-FTIR. The measurements were carried out at a power plant in Finland as part of WP2, Task 2.1. The aim of this work package is to quantify the contribution of sampling configurations available for collecting HCl in accordance with EN 1911 and accredited analytical laboratories on uncertainty, and compile evidence bases with respect to EN 1911 and portable optical systems for BAT Conclusions industries. Task 2.1 will carry out work related to the absorbing solution used when carrying out EN 1911. Specifically, the impact of different glassware configuration readily available and collection parameters will be investigated. Also, the variance of EN 1911 due solely to accredited analytical laboratories that offer chloride quantification will be isolated. VTT has extensive experience in field measurements, thus knowing well the practical challenges that emission measurement teams often face during the measurements. VTT also has significant experience in standard development and provides experts to Task Force Emissions, CEN/TC 264/WG 45 and typically lead the Finnish delegation to Annual Plenary meetings of TC 264. You can find more information on WP2 here. 28.10.2021 HEROES at Air Quality and Emissions Conference Rod Robinson and Marc Coleman of project partner NPL were invited by the organising committee to speak at Air Quality and Emissions 2021 (AQE2021). Rod gave an overview of the increasingly stringent legislation in the industrial emissions area, the measurement issues this creates, and the role that the international standards work we lead has in addressing these. Whilst Marc gave a more focussed presentation from the EMPIR project he leads regarding the uncertainties associated with measuring low amounts of hydrochloric acid (HCl) emitted from industrial processes (project HEROES 18NRM04). The conference was virtual, and 352 delegates tuned in to hear Marc and Rod talk in the keynote session ‘Low Emissions, a Positive Problem’. 26.09.2021 HEROES at the International Metrology Congress Cécile Raventos of project partner INERIS recently presented a poster on the work of the project at the International Metrology Congress (CIM 2021), held on the 7-9 September in Lyon, France. The poster Evaluation of the suitability of the HCI reference measurement method for the increasingly stringent legislation on industrial plants is available here, and also over on our Documents page. 09.03.2021 HEROES Projekti (HEROES Project) Tuula Pellikka of project partner VTT recently presented work on the project to a Finnish National Mirror Group. You can find a copy of Tuula’s presentation here (in Finnish), and also over at our Documents page. 08.03.2021 HEROES at Industrial Air Pollution Monitoring Chris Dimopoulos and Richard Harvey of project partner NPL provided presentations on aspects of work under the HEROES project at the “Industrial Air Pollution Monitoring” course hosted by University of Leeds Faculty of Engineering and Physical Sciences – online three day event that occurred in February. Attended predominantly by industry, Richard presented on Understanding instrument performance standards and Chris presented on Calculations of uncertainties in stack monitoring. You can find a copy of Chris’s presentation here, and also over at our Documents page. 16.02.2021 Peer review of papers and technical reports on the impact of HCl emissions on eco-systems and review on the impact of HCl emissions that have previously been underestimated Rupert Standring of project partner the Environment Agency (EA) has reviewed available peer reviewed papers and technical reports on the impact of HCl emissions on eco-systems. In particular, the EA reviewed work reporting on the impact of HCl emissions that has previously been underestimated and also look at the probable implications. The report Peer review of papers and technical reports on the impact of HCl emissions on eco-systems and review on the impact of HCl emissions that have previously been underestimated can be found here, and also over on our Documents page. 22.01.2021 CFD modelling of HCl droplet distributions in stacks, Uncertainty due to positioning of isokinetic sampling Stanislav Knotek of project partner CMI has provided some illustrations to the modelling work under WP1. CMI, with support of NPL, are creating a CFD model of distribution of HCl droplets in stacks. Three typical stack geometries will be considered with various flow rates around the 10 m.s-1 level. Simulation of a stack flow supplied with 100 000 droplets per second using DPMfoam solver of OpenFoam. Droplet diameter is 1 um and average flow velocity is 5 m/s Axial velocity distribution for two stacks with different shape of a supply pipe: (a) straight pipe, (b) pipe with an elbow Transversal velocity field for two stacks with different swirl pattern: (a) straight supply pipe, (b) supply pipe with an elbow Using the model developed, CMI and NPL will then investigate how the distribution of the droplets is affected by flow patterns generated by elbows (swirl) or T-junctions (asymmetric flow) in a supply pipe of the stack. CMI and NPL are looking to determine the impact of the droplet distribution to error of HCl concentration measurement using isokinetic sampling in a grid of points according to EN 15259. Current goals in this work are simulating HCl aerosol distributions in stacks with complex flow, estimating variations in HCl concentration for several typical stack geometries and estimating uncertainties of HCl concentration measurement related to selection of sampling points 22.01.2021 Successful M18 Project Meeting for HEROES A successful M18 meeting for the HEROES project was held earlier this week.
