Characterization and Control of Odours and VOC in the Process Industries

The purpose of the symposium was to present recent advances in characterization and control of odour and volatile organic compound emissions in the atmosphere, and to contribute to the state-of-the-art of measurement and sampling tools, impact prediction methods and abatement techniques. Topics covered were: Legislative aspects Emission characterization Abatement technologies, both recuperative and destructive and Reduction methods. Apart from the global problems of climate, all aspects relating to the workplace environment and official regulations were discussed.
