Elke Thisted and Hege Indresand are both members of the organizing committee of the Norwegian X-ray conference, and in september they will presents talks on some exciting new ED-XRF applications being utilized in the process industries in Southern Norway.
Elke Thisted works at Glencore Nikkelverk in Kristiansand, and she has been developing a procedure that enables a screeing and quick analysis of the content in a press filter, where an important sampling step takes place (Top figure).
In the process industry filter presses are used to remove precipitations from solutions to enable further refinement. The effectivness of the precipitation in the treatment tank can be controlled by sampling both the solution after the press and the sludge itself. The sampling procedure of the sludge in the filter press will be checked by HH-XRF to control the distribution of the precipitated elements. Results of several filter press mapping with HH-XRF will be presented.
Hege Indresand brings on-line XRF to the ambient atmosphere around a factory (Bottom pictures). She has been working with the metal producers in Southern Norway, mainly Eramet, Glencore Nikkelverk, Elkem, and Saint Gobain to try to understand the dust emissions dynamics and source profiles with on-line chemical analysis by ED-XRF.
Many industries today have goals of achieving zero-emissions processes. In this work, industries are in need of better characterization and monitoring tools to assess the air quality around the plant due to a higher need for documentation and accounting certainty. Cooper Environmental’s Xact® 625i Ambient Metals Monitor was tested for hourly analysis of ambient PM10 at several plants. The data is easily correlated with meteorology, which is an important step in understanding emissions dynamics. Indresand will present preliminary results form a 3-month study in 2017 at all three Eramet Plants in Norway (Kvinesdal, Sauda, and Porsgrunn). Note also that the inventor of this instrument, Dr. John Cooper, is one of our main speakers this year!
