Blue Hydrogen Generation Using Steam Methane Reforming

The attached diagram represents a Steam Methane Reforming (SMR) process for blue hydrogen production, with CO₂ capture. Analytical instruments play a critical role across the SMR unit to ensure:

  • High hydrogen purity
  • Effective CO₂ removal
  • Safe operation
  • Emissions compliance

  • Objective: Remove sulfur and contaminants before reforming
  • Instruments:
    • Total Sulfur Analyzer: Monitors H₂S/mercaptans in natural gas feed (to protect catalyst)
    • Moisture Analyzer: Ensures dryness of feed gas.
    • Gas Chromatograph (GC): Confirms hydrocarbon composition.

  • Objective: Remove sulfur from feed gas using adsorbents
  • Instruments:
    • H₂S Analyzer (UV or TDLAS type): Measures residual H₂S after adsorbent bed.
    • Breakthrough Monitor: Detects bed saturation.

  • Objective: Convert CH₄ + H₂O → H₂ + CO + CO₂
  • Instruments:
    • Flue Gas Analyzer (O₂, CO, NOx): Monitors burner combustion efficiency.
    • Temperature Sensors (TCs): Across reformer tubes and outlet.
    • Process Gas Analyzer (Online GC or TDLAS): Monitors reformer outlet gas for:
      • H₂, CH₄, CO, CO₂
      • Ensures proper reforming reaction conversion

  • Objective: CO + H₂O → CO₂ + H₂ (increases H₂ yield)
  • Instruments:
    • CO & CO₂ Analyzers: Track shift conversion efficiency.
    • H₂ Analyzer: Monitors increasing H₂ yield.

  • Objective: Capture CO₂ from reformate gas
  • Instruments:
    • CO₂ Analyzer (NDIR or IR type):
      • Inlet: To check CO₂ load
      • Outlet: To confirm capture efficiency
    • H₂ Analyzer: Ensures H₂ loss is minimal.
    • pH & Conductivity Sensors (in amine): Monitor solvent condition.

  • Objective: Remove residual CO/CO₂ (if methanation) or purify H₂ (via PSA)
  • Instruments:
    • Online GC / TCD or QMS: For H₂ purity (>99.9% for fuel cells)
    • CO, CO₂ Analyzers: For trace contaminants
    • Moisture & O₂ Analyzers: For fuel-cell grade hydrogen

  • Objective: Compress and send captured CO₂ for sequestration or use
  • Instruments:
    • CO₂ Purity Analyzer
    • Moisture Analyzer: Avoid corrosion during transport
    • H₂S Analyzer: Ensure captured CO₂ meets environmental specs
