32 Air Monitoring New gas sample probe provides rest-assured


precision and environmental compliance The new PSG Basic Duo Probe is a transformative solution for continuous gas analysis sampling. Built for reliability and adaptability in all levels of dust concentration, it’s a must-have solution in industries dealing with hot gases, variable dust levels, and moisture-rich conditions. This probe provides uninterrupted gas sampling, serving applications like emissions measurement, process control, and optimisation, handling low to medium dust levels with options for high dust scenarios.


With a smart design to optimise gas fl ow and the largest fi ltration surface in the market (212 cm²), the PSG Basic Duo Probe captures dust effi ciently. Filter changes are simple and tool-free and the device’s compact bracket design simplifi es maintenance. The PSG Basic Duo Probe features a high-performance heater and robust insulation to provide uniform heating up to 250°C, which is crucial for accurate analysis. Superb fi ltration prevents dust buildup with no water vapour condensation, ensuring reliable functionality. It handles up to 3 g/m³ of dust or 10 g/m³ with pre-fi lters. A 0.3 µm ceramic fi lter provides a high level of thermal and chemical resistance.


The probe enables rest-assured EU Regulations (2000/76/EG & 2001/80/EG) compliance including TI Air and 13th & 17th BImSchV, aided signifi cantly by the device’s standard calibration and test gas connections.

Taking place from 20th to 22nd September 2023 in sunny Barcelona, CEM 2023 will be our largest emissions monitoring event to date, with more exhibitors and presentations than ever! With 25 years of experience behind it and regular attendance from all around the world, this year’s conference will be CEM’s highly anticipated return to live events – and once again, our Scientifi c Committee have excelled themselves, putting together a jam- packed programme of talks and workshops delivered by thought-leaders, regulators and industry veterans from all across this global sector. As such, CEM 2023’s conference programme features representatives from many of the major national research institutions, with talks from members of the European Integrated Pollution Prevention and Control Bureau (EIPPCB), a department of the European Commission’s Joint Research Centre; the Environmental Protection Agency (United States); France’s National Institute for Industrial Environment and Risks (INERIS); the Council of Scientifi c and Industrial Research (India); the Technical Research Centre of Finland; Italy’s Institute for Energy System Research (RSE); and the Environmental Protection Agency (United States).

On the fi rst day of the conference, the EPA’s Jeff Ryan will kick off our session on new pollutants with a talk on the Agency’s perspective regarding monitoring for PFAS in air, which is now considered a signifi cant vector. This talk will feature discussion of emissions sources, like chemical manufacture, application and treatment, as well as the incineration and combustion of PFAS-containing compounds, which often result in the formation of products of incomplete combustion or destruction (PICs or PIDs). With such a range of sources, reliable and widely accepted


61169pr@reply-direct.com TALKING POINT EPA exploring new measurement methods for PFAS in air


measurement methods are critical for both characterisation and further research into the emerging threat of PFAS pollution, particularly the identifi cation of as-yet-unknown compounds that may be prevalent but are not targeted for measurement. Indeed, the complexity and variety of these substances are compounding the problem. As things stand, we are aware that PFAS are present in many forms: volatile, semi-volatile, non- volatile, polar and nonpolar. This will most certainly necessitate a whole suite of measurement approaches, some of which will be discussed in this talk through the work of the Environmental Protection Agency’s Offi ce of Research and Development (ORD) and Offi ce of Air Quality Planning and Standards (OAQPS). Some of the new methods being developed by these Offi ces include: Other Test Method 45 (OTM-45), formally posted in 2021, for polar semivolatile and nonvolatile PFAS compounds; OTM-50, currently under development for nonpolar volatile PFAS compounds using whole air canisters; and OTM-55 for non-polar semi-volatile and non-volatile PFAS compounds, including fl uorotelomer alcohols (FTOHs) and PIC/Ds.


With two rooms running sessions in parallel over all three days of the conference, attendees to CEM 2023 will have full access to a whole host of presentations that will provide process operators, plant managers, laboratory technicians, instrument users and apprentices with the latest information on developments in emissions monitoring and measuring applications, regulations and technologies.

Advanced testing of materials for hydrogen now available to APAC energy industries DNV, the


independent energy expert and assurance provider, has expanded its research laboratory in Singapore with new testing equipment for the safety assessments of hydrogen transport and storage facilities.


As several gas network operators in the APAC region are exploring the opportunity to transport hydrogen through adapted or repurposed infrastructure, DNV’s new test chamber can be used to evaluate whether existing pipelines can safely transport hydrogen – either blended with natural gas or in pure form.


DNV is currently providing technical advice and support on the integration of blended hydrogen into gas trunkline assets in India – including transmission pipelines, interconnects and spur lines, compressors, valves, and metering stations and equipment. The company is also assisting Korea Gas Corporation (KOGAS) in a two-year project to assess the viability of blending hydrogen into South Korea’s gas transmission network.


In technical terms, the new equipment in Singapore provides a hydrogen-ready integrated solution for fatigue crack growth rate (FCGR) testing. The test chamber includes hydrogen booster systems, safety and hydrogen alarms, ventilation systems, and an additional test vessel.


DNV’s experts in Singapore will employ the new equipment to assess the fracture, fatigue, and corrosion performance of pipe material such as steel for varying concentrations of hydrogen under different operational and environmental conditions, such as high pressure. Testing is necessary because hydrogen can make steel more brittle and prone to stress cracking. Hence, fracture resistance and fatigue crack growth rates obtained from laboratory testing of the steel and welds in hydrogen environments are essential parameters to assess the integrity, risk of fracture and remaining life of pipelines and equipment for hydrogen service.


DNV is active across the whole hydrogen value chain and has delivered approximately 200 projects globally in the last few years. This new lab facility will substantially support the growing need for hydrogen related services in the APAC region and reinforce DNV’s global position on materials testing recognised from its leading-edge labs in the UK (Spadeadam) and the USA (Columbus). Bringing materials testing for hydrogen to the APAC region enhances DNV’s wider and growing role in supporting the development of future hydrogen value chains and ensuring the safety of facilities through risk advisory, asset integrity and regulatory change.


“This latest investment in our Singapore research and test laboratory offers our APAC customers the advanced testing capabilities energy and other industries are asking for as private and public investment gets behind building local and regional hydrogen economies,” said Brice le Gallo, DNV’s Vice President and Regional Director, Energy Systems for Asia Pacifi c. “Assurance that hydrogen transportation and storage is safe and reliable can unlock the scale-up of its use to solve major decarbonisation challenges such as reducing piped natural gas use in homes and industry.”
