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.
