Finding the right technology for coal gasification for Indian coal has been a challenge. Jindal Steel and Power Ltd (JSPL), in its Angul plant, is successfully running a gasification project based on fixed bed technology for steelmaking under the DRI route and is planning to increase its capacity.
14 Jan 2020, 2:30 am. Angul/New Delhi: JSPL ( Jindal Steel and Power Limited) coal gasificationbased DRI (direct reduced iron) plant in Odisha's Angul district has become operational. The operations in the plant had been halted due to a scarcity of coal. However, the plant, whose total capacity is MTPA, has resumed its operations, JSPL ...

The optimization results show that only 3 large centralized coal gasification (CG) hydrogen plants without CCS units are selected (see Table 4). The CG hydrogen plants considered the least expensive feedstock fuel (, coal). Coal is and times cheaper than natural gas and biomass, respectively (see Table 3). In addition, CG plants ...
This can be done by using lowcarbon energy sources such as hydrogen, coal gasification, or electricity instead of the traditional carbonintensive manufacturing route of coalfired plants. ...

India is also the largest producer of sponge/direct reduced iron (DRI), estimated to be Mt [6, 25]. Worldwide, natural gas is the fuel typically used while in India 82% of DRI is produced in coalbased rotary kilns with the remainder being produced via gasbased routes (natural gas, syngas from coal gasification, coke oven gas, and gas ...
The Union Steel Minister, Shri Ram Chandra Prasad Singh chaired a meeting here with the stakeholders from the steel industry, consultancy providers and CSIR Central Institute of Mining and Fuel Research (CIMFR) along with officials of Steel Ministry to deliberate on the prospects of using coal gasification in steel production through the Direct Reduced Iron (DRI) route.
6% in 2000 and nearly 8% in 2019. Global DRI production rose by ~8% to 108 Million tonnes (Mt) in 2019 compared to 2018, representing the fourth consecutive record year for DRI production (see Figure 1). In 2020 DRI production numbers slightly declined due to the COVID19 pandemic, but DRI processes are currently again winning strong support due to
From a technical perspective, the challenge of decarbonization involves two processes: chemical reduction for iron ore refining (process emission), commonly with metallurgical coal and coke, and from the high temperature heat sourced required to operate BF and other production reactors [ (Friedmann et al., 2019)].
The metallization rate of the end product, called Direct Reduced Iron (DRI) or 'sponge iron', ranges from 85 percent to 95 percent (often even higher). In 2008, Mt of DRI was produced worldwide, using primarily MIDREX technology ( percent). ... Coal gasification is the result of a reaction with oxygen and iron ore in a liquid state ...
A CoalCokeHydrogenIron (CCHI) system, lowrank coal pyrolysis coupled with gasification based on pilot test to hydrogenrich gas for direct reduced iron (DRI), was proposed.
The main technology being used is coal gasification instead of burning the fossil fuel, it is chemically transformed into synthetic natural gas (SNG). The process is decades old, but recent ...
Jindal Steel and Power Ltd (JSPL) on Tuesday said its coal gasificationbased DRI plant at Angul district in Odisha has resumed operation. "JSPL's 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.
"We are targeting an additional production runrate of million tonnes per year of steel in FY2021 through CGP (coal gasification process) and DRI route," Sharma said.
"Further, India can produce the cheapest hydrogen through the coal gasification route," Sharma added. ... MT direct reduced iron, MT steel melting shop, MT conventional hot strip ...
Based on the result of the work, the proposed biosyngas DRI route has comparable energy demand compared to other DRI routes, such as the wellestablished coal gasification and natural gas DRI route.
The coal gasification plant would use local Indian coals to generate a synthesis gas (or syngas) that can be an acceptable reducing gas source for producing DRI in a shaft furnace.
The 75% of DRI or HBI is produced with processes based on natural gas as energy resource, which has to be converted by gas reforming technology to reducing gases (CO and H 2) for the reduction of iron oxide to metallic iron. In the present chapter, the different plant layouts are described.
