US steel producer Nucor has awarded Tenova HYL a contract for the world’s largest single DR module.

Nucor will install a 2.5Mt/y Energiron ZR plant using Tenova HYL’s reformerless process design. The plant will be built in Louisiana, and supply high carbon DRI to Nucor steel plants.

The plant will be designed to produce cold-discharge DRI of 96% metallization and 3.0% carbon in the form of iron carbide, which will be shipped to Nucor’s producing facilities that will use the DRI in their steelmaking process.

The Energiron ZR process allows the selective capture of CO2 which can be commercialised as a by-product.

The DR plant will comply with environmental regulations by the EPA in terms of NOx, SOx and other pollutants, having already been granted the corresponding air permit in Louisiana.

The project covers the full supply of the DR plant, license, training and technical assistance in commissioning and start-up.
