Technical details and manufacturing context for Gas Reforming Unit

Definition
The Gas Reforming Unit is a critical component within the Integrated Direct Reduction Iron and Electric Arc Furnace Steelmaking System. It processes natural gas or other hydrocarbon fuels to produce a reducing gas mixture (primarily H₂ and CO) essential for the direct reduction of iron ore in the shaft furnace. This unit enables the substitution of coke with natural gas, reducing carbon emissions in the primary ironmaking stage.
Working Principle
The unit typically operates on steam methane reforming (SMR) or autothermal reforming (ATR) principles. In SMR, natural gas reacts with steam over a nickel-based catalyst at high temperatures (700-1000°C) to produce syngas (H₂ + CO). The reaction is endothermic, requiring external heat. The produced syngas is then conditioned (e.g., cooled, purified) before being fed to the direct reduction reactor.
Common Materials
Nickel-based catalyst, High-temperature alloy steel (reactor tubes), Refractory lining, Carbon steel (structural)
Technical Parameters
  • Syngas production capacity, typically ranging from 50,000 to 500,000 Nm³/h for industrial steel plants. (Nm³/h) Customizable
Components / BOM
  • Reformer Reactor
    Houses the catalyst where the reforming reaction occurs under controlled temperature and pressure.
    Material: High-temperature alloy steel (e.g., HK-40, HP-modified)
  • Catalyst Tubes
    Contain the nickel catalyst; designed to withstand high temperatures and thermal stress.
    Material: Centrifugally cast alloy steel
  • Burner System
    Provides the necessary heat for the endothermic reforming reaction in SMR configurations.
    Material: Heat-resistant steel
  • Waste Heat Boiler
    Recovers heat from the hot reformer effluent to generate steam, improving energy efficiency.
    Material: Carbon steel / alloy steel

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Catalyst Deactivation
Cause: Poisoning by sulfur compounds, carbon deposition (coking), or sintering due to high-temperature operation exceeding design limits, leading to reduced reforming efficiency and increased pressure drop.
Reformer Tube Failure
Cause: Creep rupture from prolonged exposure to high temperatures (typically 800-950°C) and thermal cycling, exacerbated by internal carburization or hot spots due to flame impingement or catalyst maldistribution.
Maintenance Indicators
  • Abnormal increase in reformer outlet temperature or tube skin temperatures indicating catalyst degradation or flow maldistribution
  • Sudden drop in hydrogen purity or rise in methane slip in product gas, signaling catalyst deactivation or reactor leaks
Engineering Tips
  • Implement rigorous feedstock sulfur removal (<0.5 ppm) and controlled steam-to-carbon ratios to minimize catalyst poisoning and coking, with regular catalyst activity monitoring via temperature profiles and product analysis.
  • Use infrared thermography for continuous reformer tube temperature mapping to detect hot spots early, combined with scheduled decoking cycles and strict adherence to startup/shutdown thermal ramp rates to reduce thermal stress.
