UTILITY OPTIMIZATION CAPABILITIES (VM-ERTO)
Whatever utilities the process needs, the process gets.
How can we get those utilities needs to the process in the cheapest possible way…
within emissions constraints…
within current operating constraints, and
within contractual constraints?
Target is the minimization of total operating cost (Fuel+Power+BFW+Others)
Customized or pre-defined Excel based reports
provide operating guidance
What-if capabilities

20. NEXT STEPS
Improvement of KPI calculations and balances
Addition of hydrogen network and its integration to the steam, power and fuel existing
networks
Lost Benefit Analysis: Evaluate the potential lost benefit by running in parallel an unconstrained model to
compare with current case
Based on the “original” ERTO model, no additional configuration needed
Historize savings and optimization solution
Compare constrained versus unconstrained savings to analyze and decide if worthwhile the expansion of
certain optimizer limits and availability
Additional unconstrained scenarios
Analysis of the impact on savings of a given set of Individual optimization variables

22. CONCLUSIONS
The integrated steam, power and fuel network of the Motiva Port Arthur site have been modeled inVisual
MESA Energy Real Time Optimizer.
The system is running unattended every 30 minutes generating a list of recommendations for operations to
reduce the utilities' costs.
Significant savings were captured.
The model is also used to evaluate “what-if” cases such as turnaround planning and investment planning.
