IP & E APPLICATION
DIRECT REDUCTION IRON
Accurate gas measurements ensure direct reduction iron ( DRI ) plants can operate at the highest levels of efficiency , while achieving low emissions targets .
The Midrex DRI process is a low carbon dioxide emission application in steelmaking using virgin iron ore in an electric arc furnace . The iron ore is heated as it descends through a shaft furnace , and oxygen ( O 2 ) is removed from the ore using counterflowing gases with a high hydrogen and carbon monoxide content . This process requires accurate gas monitoring for efficient operation .
Emissions monitoring is also important in the DRI process . The reaction between the counterflow gases and iron oxide in the ore produces metallic iron , water vapor , and carbon dioxide ( CO 2 ). The process may generate oxides of nitrogen ( NOx ) which must be continuously monitored to ensure environmental compliance .
KEY SOLUTIONS
The SERVOTOUGH Oxy 1900 provides essential O 2 monitoring in the DRI process . This is an industry-leading Paramagnetic O 2 analyzer designed for hazardous areas . It is supported by the highly flexible SERVOTOUGH SpectraExact 2500 photometric analyzer for the other measurements . The SERVOPRO 4900 Multigas and SERVOPRO NOx analyzers provide the required continuous emissions monitoring .
