Jindal Steel & Power Limited (JSPL) is to build a 1.8Mt/y coal gasification-based Midrex DRI plant in Angul, Orissa, India.
The new module will pair commercially available gasification technology from Lurgi of Germany with a 7.15m Midrex shaft furnace to produce direct reduced iron (DRI) for use in meltshop applications.
It will be the first time a Lurgi gasifier will be paired with a Midrex furnace and the installation will use Indian coal and iron ore.
The new plant will have the flexibility to produce cold and hot DRI (HDRI) for charging to a new greenfield meltshop supplied by Germany’s SMS Siemag. It will use a hot transport conveyor similar to that installed at Hadeed Module E in Saudi Arabia. This system will be supplied by Aumund.
The Angul Plant will use syngas produced in the gasification plant to produce DRI for melting in an EAF. Coal gasification is the process that converts coal to synthesis gas by partial oxidation using oxygen and superheated steam as the reactants.
The synthesis gas mainly consists of carbon monoxide, hydrogen and methane which will be used as a reducing agent for the iron oxide to produce DRI in the shaft furnace.
A coal gasification plant can use a variety of low cost fuels, such as bituminous and sub-bituminous coal, lignite, pet coke and petroleum refinery bottoms to generate a synthesis gas.
