Direct reduction iron production

Expert gas analysis solutions for your DRI process and emission monitoring

Accurate gas measurements play an integral role in ensuring direct reduction iron (DRI) plants operate at the highest levels of efficiency while achieving low emissions targets. Our range of analytical solutions ensure effective results across the process.

Gas analysis is needed for process control in iron ore reduction

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 (O2) 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.

Continuous emissions monitoring is a key requirement

Emissions monitoring is also an important part of the DRI process. The reaction between the counterflow gases and iron oxide in the ore produce metallic iron, water vapor, and carbon dioxide (CO2). In addition, the process may generate oxides of nitrogen (NOx) which must be continuously monitored to ensure environmental compliance.

Effective solutions across the DRI process

Servomex supplies the SERVOTOUGH Oxy 1900 for essential O2 monitoring in the DRI process. This is an industry-leading Paramagnetic O2 analyzer designed for hazardous areas. This is supported by the highly flexible SERVOTOUGH SpectraExact 2500 photometric analyzer for the other measurements. The SERVOPRO 4900 Multigas and SERVOPRO NOx analyzers provide required continuous emissions monitoring.
