Williams Refining LLC, a petroleum/petrochemical division of Williams Energy Services, needed a major revamp to increase capacity and yield performance at its fluid catalytic cracking (FCC) unit in Memphis, Tennessee.
Project, procurement, engineering and construction management services were provided by IAG, deploying the latest technology from UOP LLC. From the start of engineering to completion of the turnaround, the entire project was completed in less than one year.
IAG had already completed numerous turnkey FCC revamps, and the project team approach adopted by Williams included many members with long track records in FCC turnaround specialties. At the time, IAG staff averaged 26 years of refinery experience.
IAG assisted in the final technology selection and an analysis that included cost, constructability, downtime and payout factors. IAG analyzed numerous revamp options and assessed each according to Williams’ prescribed constraints, which included cost-effective retention of existing structure, turnaround start and completion dates, and capital limitations.
