Today already, the route combining NG based ...
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. ... (DRI) route, where the fuel can be coal or natural gas. India presently produces around 90% of crude steel through the BF and coal based DRI routes ...
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.
Through the history of gas generation and use, coal has been the lead feedstock for the gasification of carbonaceous materials. This chapter presents an assessment of the technologies that have evolved for the gasification of coal with a description of the current state of the art of the various technologies. Various types of coal are available ...
The flow process of CCHI system is shown in Fig. coal is firstly fed into the pyrolysis unit to gain the gasified coke and hydrogenrich pyrolysis gas (5860 vol% H 2, 2327 vol% CH 4 and 58 vol% CO) [25].Then the gasified coke together with steam and oxygen from the air separation unit (ASU) are fed into the gasification unit to further produce the gasification gas (mainly ...
The broad results of our gasification economy framework for the Indian economy based on gasification and carbon capture has been depicted in Table assume that the large Indian coal endowments with appropriate blending can be seamlessly accessed and commercially exploited to build high value competitive and sustainable methanol, steel and ammoniabased gasification value chain.
of INDUSTRY TYPE: Coal Gasification Plant(CGPPlant) Multinational company involved in the mining, steel production, power generation, oil exploration and making new presence in producing steel through Coal Gasification (Syn gas) with Syn Gas based DRI route and involvement in Coal to Diesel Project.
In a coal gasification based DRI plant, biomass gasification only makes economic sense under specific and unlikely conditions of low biomass cost and high gasification capacities (< 4 USD/GJ biomass price for a 100 MW ... (BFBOF) route, and the electric arc furnace (EAF) route, which are shown in Figure 1.

For the steel making process through blast furnace route requires coking coal which is mostly imported from Australia, USA and other ...
The scrapbased electric arc furnace (EAF) steelmaking route has been increasingly adopted worldwide due to its low capital cost and flexibility, but its future growth will depend on supply of highquality virgin iron via other emerging routes, especially DRI. Coal injection can also promote improved slag foaming in the EAF, so some highrank ...
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 ...
The Blast Furnace came up in a record time of 27 months, establishing new benchmarks in global steelmaking. The Integrated Steel Plant, initially envisaged as the country's first steel plant to be based on purely swadeshi raw material, involved setting up world's largest Coal Gasification Plant (CGP) for Steelmaking through the DRI route.
coal gasification, and EU and US grid power is less efficient than SMR. • In natural gasbased economies like the United States, the predominantly SMRbased ... The DRI route only emits 25 kgCO 2 while consuming approximately 50 kg of hydrogen, in turn using 2,633 kWh of power. This suggests an emission reduction
Steam/coke ratio is an essential parameter in the gasification process to improve the quality of gasification gas (used in the DRI process), and further affects the. Conclusions. A system of lowrank coal pyrolysis coupled with gasification on the basis of pilot test to hydrogenrich gas for direct reduced iron was proposed and modeled.
The gasification reaction supplies the energy required for the metallurgical reactions and for the melting of compacted DRI and coal ash to produce hot metal and slag. The exit gas consists mainly of CO and H 2 at a temperature of 1000 °C, the gas is subsequently cooled and dedusted.
Coal Gasification OptionAn alternative option generating significantinterest in India is the use of a coal gasificationplant in combination with a Direct Reductionplant. The coal gasification plant would uselocal Indian coals to generate a synthesis gas (orsyngas) that can be an acceptable reducing gassource for producing DRI in a shaft furnace.
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
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 diversification of coal for its sustainable utilization in producing liquid transportation fuel is inevitable in countries with huge coal reserves. Gasification has been contemplated as one of the most promising thermochemical routes to convert coal into highquality syngas, which can be utilized to produce liquid hydrocarbons through catalytic FischerTropsch (FT) synthesis.
