For more than 20 years, the cement industry has been using alternative fuels and raw materials for cement production. Mainly industrial plastic, solvents, or waste wood are used as additives. In order to measure emissions of potentially environmentally hazardous substances resulting from the addition of alternative fuels, measurements at the stack of the blast furnace system became necessary.
Background
Solution
V&F Ion Molecular Reaction Mass Spectrometry (IMR-MS) can determine inorganic and organic volatile compounds emitted during the process. Alternative fuels typically show only a minor effect on the composition of the flue gas in terms of sulfur containing compounds such as SO2, CH4S, COS and C2S and nitrogen containing compounds such as NH3 or NO2, or organic compounds.
Advantage
V&F equipment can be used during concrete production to continuously measure emissions at the stack. Since the results are available immediately, potentially hazardous emissions can be suppressed and the production process can be adjusted in a timely manner. User-friendly calibration routines allow measurements of absolute concentrations. Depending on the result, the process can be suitably modified by adjusting it to use alternative fuels.
