Why Automate & Optimize?

System Complexity

  • Multiple facilities, different designs

  • Pipeline and plant constraints

  • Different Sales contracts / delivery pressures

  • Changing volume mix

Changing Conditions

  • Catalyst activity

  • Equipment Fouling

  • Energy Costs

  • Customer Demand

  • Plant Personnel & Plant Availability

Choice

  • On-purpose H2 production rates vs By-product sources

  • Product Storage/ Cavern Utilization

  • Operating parameters

  • S/C Ratio, Excess O2, Reformer Severity, Other.

Optimization needed for complex systems with constraints and available degrees of freedom
