In 2014 Jindal Steel and Power Limited (JSPL) in Angul, Odisha, India commissioned the world’s first MXCOL® DRI Plant featuring a coal gasfier to supply syngas for direct reduction in a MIDREX® Shaft Furnace. JSPL’s MXCOL® Plant started producing direct reduced iron (DRI) at 93% metallization and produces both hot DRI (HDRI) and cold DRI (CDRI). The syngas from coal is used instead of natural gas to produce the reducing gas and fuel gas required for reduction of iron oxide in the MIDREX® Shaft Furnace. The coal gasification unit is able to utilize and process India’s domestic high ash coal and the parallel commissioning and startup of the MXCOL® Plant and Lurgi-based Coal Gasification Plant proved that MXCOL® is a commercially viable option for steelmakers located in the areas where the option for using natural gas is limited.
