Air emissions

Competence

VTT performs varied research into the characterization and control of emissions originating from different sources, such as power plants, industrial processes and traffic. For this purpose, VTT has diverse measurement techniques and we also develop new innovations with industry and analyser manufacturers for the determination of emissions together.

Challenges

Concern about environmental issues is increasing rapidly due to global environmental challenges, such as climate change and global warming, health risks caused by fine particulates etc. This growing demand in environmental monitoring issues (from individuals, companies, politicians and researchers) is creating an urgent need to characterize the emissions, including from those sources which have not been monitored until now. Only then can the cost-effective measurers that are needed (abatement, process optimisation, control, surveillance), be focused on those sources which are the most critical ones.





Solutions

  • Determination of relevant properties (size distribution, number etc) of fine particulates
  • Integration of aerosols and flow dynamics in modelling of chemical gas phase and surface reactions
  • Special measurement methods for gaseous components (including greenhouse gases)
  • Development of emission control devices, such as catalytic converters for vehicles
  • Development of safe synthesis, handling and monitoring technologies for nanomaterials

Benefits

  • Reliable and internationally comparable information about emissions
  • Financial benefit through process optimisation
  • Lower environmental impacts, reduction in emissions

References and merits

  • Participation in the international organisations, such as CEN (the European Committee for Standardisation)
  • Several patented innovations (rotating pitot-type flowmeter, sampling system based on porous tube dilution)
  • Development of novel mercury analyser for emissions together with Gasmet Technologies Ltd.
  • Revision of emission factors for N2O and CH4 in Finland, results used in the Intergovernmental Panel for Climate Change, IPCC
  • Capacity building projects dealing with the emission measurements and odours in Russia, the Baltic countries, India and Uruguay.
