IRON & STEEL

Engineering Competitive Steel Production Through Integrated Systems

Approach image

OUR APPROACH

We design integrated systems that optimize blast furnace operations, enable pragmatic DRI (Direct Reduced Iron) pathways, embed process improvements at design stage, and convert waste streams into value—reducing energy intensity and costs while achieving substantial emission reductions as the natural outcome of superior engineering.

Our solutions balance growth and operational excellence with economic viability, ensuring steel producers remain competitive while meeting regulatory requirements.

Our Solutions

Integrated Technology Solutions

  • Gasification for Clean Ironmaking: Convert domestic coal or refinery waste (petcoke) into syngas for
  • DRI Production: Syngas replaces natural gas in shaft furnaces, providing fuel flexibility and reducing import dependency
  • Hydrogen Generation: Extract H₂ from syngas via PSA for hydrogen-based DRI
  • Chemical Co-Production: Convert CO₂ to methanol or acetic acid
  • Cost Advantage: $4-5/MMBTU syngas vs. $12-15/MMBTU imported LNG (60-70% savings)

AI-Driven Process Optimization

Machine learning models for:

  • Blast furnace control: Real-time optimization of burden distribution, blast parameters
  • Energy forecasting: Predictive models for electricity demand, enabling grid flexibility
  • Quality prediction: Reduce off-spec production through advanced analytics
  • Maintenance optimization: Predictive maintenance reducing downtime 20-30%

Grid Integration & Energy Storage

Steel plants as grid flexibility assets:

  • Demand response: Shift EAF operations to low-price/high-renewable hours
  • Thermal storage: Store waste heat for later use or grid balancing
  • Battery integration: Smooth power demand, capture arbitrage opportunities
  • Ancillary services: Provide frequency regulation, voltage support to grid operators

Embedded Process Improvements

Design integration from project inception, not as retrofit:

  • Blast furnace gas optimization: 15-25% CO₂ concentration ideal for economic recovery
  • DRI off-gas management: High-purity streams for process integration
  • Cost efficiency: 30-50% lower implementation cost vs. post-construction retrofit
  • Utilization pathways: CO₂-to-chemicals, EOR, mineralization in slag/concrete
