The scope of a Margin Optimization Engineer includes the transition of key basic data, scheduling, planning, and/or assurance/lookback activities from various C+P assets.

Economic Model Coordinator:
  • Responsible for developing and maintaining up-to-date planning and scheduling models that provide a fit-for-purpose representation of the refinery/base chemical capabilities and constraints.

Seek to understand shifts in data fit including identifying potential operating issues by collaborating with technologists.

Where not in place, develop and conduct analysis utilizing other planning tools such as APS (Orion) to identify potential data differences between LP, Scheduling, and actual site performance.

Lead process of Generating new models if required with Planning Advisor

Refinery Economist:
  • Running sensitivities in the linear program (LP - PIMS) to ensure the refinery operation is optimized between monthly operating plan (MOP) cycles.
  • Determining break-even pricing and advising Trading and Supply on spot purchase and sale opportunities.
  • Assess site actual performance vs planned performance using the Margin Variance Analysis (MVA) process.
  • Assisting the Refinery Crude Economist in identifying LP model inaccuracies and general improvements to the Economic Model Coordinator.

• Coordinating seasonal product schedules with Trading & Supply schedulers to ensure successful blend-up and blend-down is achieved for gasoline and distillate products across the supply chain, while minimizing giveaway.

• Validating blend recipes produced by the linear program (LP) model in PIMS and translating the monthly operating plan (MOP) into a detailed schedule in Orion and into clear direction for Operations. Close coordination with the Refinery Scheduler is required to ensure processing unit operations are optimized.

  • Value of Hydrocarbon Stocks, Crude and Products exceeding $10 Mln USD per month
