Led discussions with Baytown Refinery leadership, processing unit owners and coordinators/schedulers advising on profitable dispositions for feedstocks, gasoline and distillate component streams basis market dynamics. Developed the monthly and weekly economic strategies for all refinery processing units by leveraging complex linear programsAdvised refinery leadership and processing equipment owners on the credit basis for “break-in” maintenance on equipment that limit refinery profitability. Developed the economic basis for projects that debottleneck refinery constraints, increasing the throughput and/or efficiency of different processing units by 3-4% on averageSpearheaded the transition of the economic toolset used to calculate refinery economics to a more robust linear program with projected value capture of over $20M/y in refinery margin improvement. Led best practice discussions with other ExxonMobil USGC refining sites aiding in economic tool set transitions regionally
