"JSPL's 1.80 MTPA DRI (direct reduced iron) plant based on coal gasification process has resumed operations in Odisha's Angul district," the company said in a filing to BSE.
The plant was not operational for long due to the scarcity of coal. Now Coal India Ltd (CIL) and its arm Mahanadi Coalfields Ltd have started selling coal in adequate quantity, therefore gasification and DRI operations have resumed.
"Our... plants are again working on the full potential on purchased coal," JSPL MD V R Sharma said.
"We are targeting an additional production run-rate of 1.50 million tonnes per year of steel in FY20-21 through CGP (coal gasification process) and DRI route," Sharma said.
Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction.
The plant was set up by JSPL to ensure the availability of chemical and thermal energy required to produce DRI at an affordable price to reduce environmental impact of coal in the long run.
The coal gasification process converts high-ash grade coal into synthesis gas or Syngas. The syngas has replaced the costlier natural gas being used by other DRI manufacturers across the globe.
The syngas is used as a reductant in converting iron ore/ iron pellets into DRI /sponge iron.
"It is the first plant of its kind in the world where syngas is used in making DRI," the filing said.
JSPL said that it has invested thousands of crores to build the Direct Reduced Iron plant and coal gasification plant.
The syngas produced from coal gasification contains methane, carbon monoxide, hydrogen and other such useful gases, in a particular ratio, which are required to produce DRI from iron ore/pellets.
This gasification process has a lesser impact on the environment as compared to the coal combustion process.
The shares of the company were trading at Rs 178.40, up 0.28 per cent on BSE in the morning trade. SID DRR
