      • Objective of the successive steps: desulfurization, steam reforming, CO shift, hydrogen purification.
  • ANALYSIS OF SMR OPERATING CONDITIONS

      • Process flow scheme.
      • Material balance, conversion, yields at various steps.
      • Feedstock and product quality: natural gas, demineralized water, hydrogen quality.
      • Operating conditions and control loops.
      • Characteristics of the chemical reactions involved: thermodynamic and kinetic aspects, their consequences on the operation, side reactions and optimum operating conditions to limit their evolution.
      • Role and mechanism of a catalyst: chemical and physical characteristics, effect of poisoning and ageing.
      • Influence of operating conditions on hydrogen production and on downstream steps.
      • Hydrogen purification:
      • Adsorption (PSA) and methanation: comparison of performances.
      • Influence of operating parameters on hydrogen purity, CO2 absorption and amine regeneration.
      • PSA unit characteristics and operation.
  • STEAM REFORMER FURNACE OPERATION

      • Different types of furnaces: technology, furnace efficiency, operating parameters, control and safety loops.
      • Catalyst loading procedure.
      • Behavior of the tube bundle. Mechanical and thermal stress.
      • Routine operation and main operating constraints.
  • STEAM PRODUCTION

      • Water preparation: drawbacks arising from impurities in water, water quality measurement, characteristics of feed water, thermal degassing, chemical conditioning of water.
  • OPERATION & START-UP

      • Key operating parameters and overall process optimization, interactions between process steps, catalyst cycles management.
      • Principles of start-up procedure: preparation, ignition, temperature build-up, feed in.
  • DISTURBANCES & TROUBLESHOOTING

      • Disturbances: modification of the steam/HC ratio, decrease of feed flowrate, change in feed composition.
      • Incidents: pretreatment reactor runaway, tube rupture in the furnace, absorption section bypassing.
