Salzgitter Flachstahl GmbH has commissioned Tenova for the construction of µDRAL, a demonstration plant for producing Direct Reduced Iron (DRI), using up to 100 percent hydrogen as a reducing agent.
The plant is based on the ENERGIRON® technology and will be installed on the premises of the Salzgitter steel mill at Salzgitter, Germany. Salzgitter Flachstahl GmbH is the largest steel subsidiary in the Salzgitter Group.
The µDRAL will have a nominal production capacity of 100 kg/h and will be operated with hydrogen and natural gas showing the flexibility of the technology in terms of fluctuating availabilities of reducing agents, including 100 percent hydrogen. The DRI produced by µDRAL will be both used in the blast furnace process to save injected coal and in the electric arc furnace of the Peine plant.
“The new direct reduction plant is the next step toward realizing the SALCOS® approach and we are proud to be the partner of Salzgitter’s transformation process to green steelmaking,” said Markus Dorndorf, business development director iron and steelmaking at Tenova LOI Thermprocess.
The ENERGIRON process, jointly developed by Tenova and Danieli, represents the base for the plant design and is the most feasible high-intensity H2 DR system available, already designed for extremely low CO2 emissions while processing iron ore pellets. This enables Salzgitter to achieve the long-term CO2 reduction targets, defined with SALCOS approach.
The ENERGIRON solution has been also recently selected by HBIS Group for the first ever gas-based DR plant in China and by OMK in Russia for the production of the highest quality of steel grades.
Tenova is a leading company specialized in innovative solutions for the metals and mining industries.
