Decarbonisation Pillars for Steel Business

  • Syngas based production
  • Resource optimisation
  • Pellet feed in blast furnaces
  • Zero waste approach
  • Zero power furnace
  • Heat recovery from off gases
  • Heat recovery from slags
  • Use of renewable power
  • Maximizing hydrogen usage from existing 55-60%
  • CO2 to CO
  • CO2 to syngas
  • Dry reforming of CO2

​

  • Fuels – bioethanol
  • Chemicals – methanol
  • Biological – crude algae oil (biodiesel/ SAF)

CO2 Minimization

JSP is deligently working to minimize CO2 emissions

  • Only company to produce low carbon steel using syngas
  • Syngas promotes usage of ~55% hydrogen – transition to 100% usage under progress
  • Complete recovery of by-products enables cutting down of scope 3 emissions
  • Focus on utilization of locally available natural resources, reducing dependency on imports

Commissioning of Zero Power Furnace (ZPF)

CO2

Avoidance

Figure: ZPF with HMTD @ JSPL

  • Low Capital as well as Time Investment in comparison to BOF.
  • High Productivity.
  • High Yield.
  • Reduction in Co2 Emissions.
  • Zero Electrode Consumption.
  • Less Refractory Consumption.
  • Less Slag Generation.

Advantages of ZPF

JSP has installed a 250 tons ZPF that reduced carbon emissions of 0.3 - 0.4 tons per ton of crude steel

Multiple levers can be leveraged to reduce emission intensity within existing setups

Recycling & Renewable

Efficiency

Fuel, Feedstock Switch

Process

By-product

    • Waste gas heat from HE & WBE to increase temperature of green pellet
    • Use of slag in place of limestone (basis availability)

Fuel

IBRM, Flux

    • Use of alternate fluxes (pyroxenite / olivine / brucite/ magnesite)
    • Use of chemical organic binders (Peridur, Alcotac) instead of bentonite
    • Use of high-grade ore, washed ore to reduce gangue content, LOI
    • Use of high quality bentonite to reduce silica at BF (lowering coke addition at BF)

Fuel

    • Increase temp. of air entering firing zone
    • Optimize fuel gas flow rate basis the change in productivity

Energy

    • Use of bio charcoal / biomass instead of coke
    • Use of hydrogen-bearing gas fuel during ignition
    • Reduce suction losses in fans
    • Pellet car condition monitoring system
    • Variable frequency drives (VFDs) to optimize power consumption
    • Advanced process control for improved power and gas consumption

​

    • Reduce recirculation load
