Topic: PERED

Abstract: The PERED® Direct Reduction Process is a New Improved energy efficient technology converts iron oxides, in the form of pellets or lump ore, by reacting with CO & H2 to highly reduced products like CDRI, HDRI & HBI suitable for steel making with flexibility to work with different raw material and energy sources and reducing the overall cost with salient features as below.

  • PERED® Vertical Shaft Furnace designed to improve the solid & gas flow patterns to improvise the reaction being taken place designed to have higher production rate / volume of reduction zone.

  • Decrease clustering possibility

  • Solid material flow regulation with less fines generation, Eliminates possible pollution due to leakage, lower maintenance cost & utilization of available heat for In-situ reforming and higher Carbon formation.

  • Top & Cooling Gas off takes to reduce fines carry over to decrease oxide loss and to improve life & efficiency of Ducts, Scrubbers & Clarifier

  • State of the art 360 degree rotating independently controlled burden feeders

  • Utilization of Process Gas Compressor capacity with less power consumption.

  • High efficient recuperator along with steam generation to decrease the exit flue gas as low as 250 Deg.C. With lower NG consumption with improved life for tube bundles.

  • Safe & High efficient Reformer with Super active PERFORMEX catalysts

At present three plants rated capacity 0.8MTPA are in operation in Iran and results near to the expected values even with the inferior quality pellets. Two more plants under construction. Development of Jumbo module with higher capacity up to 2.0 MTPA with different kind of products like CDRI, HBI & Hot charging to EAF are under progress. With the success of the PERED® Technology, More plants are expected to use this technology in Iran as well all around the globe.
