Emissions of air pollutants from industrial sources are of major public concern in Germany. Remarkable efforts have been made to control and reduce there emissions. A strong reduction of these so-called classical air pollutants like e.g. SO2 out of channeled industrial sources could be recorded throughout the last years. However, at some industrial sites there are still several measurement problems that cannot always be solved appropriately by conventional measurement systems. For example, screening of fugitive emissions or sudden releases out of leakages is difficult to monitor correctly by conventional point sensors. In these cases the open-path FTIR method can show up with several advantages because of its measurement principle. In this paper, different open-path measurements at industrial sites are presented, including measurements of sudden releases of ammonia and measurements at and above an olefin production plant.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
