Early Planning to Evaluate Alternatives for a Complex Refinery Shutdown

摘要

For an 8 month period between late 2002 and early 2003, Chevron’s Pascagoula Refinery conducted a complex series of plant turnarounds aimed at allowing that refinery to make clean gasoline and diesel. This paper discusses the technology and work processes used to evaluate the raw material, product, and shutdown alternatives during the early planning phase of this project. For very large projects like the one discussed in this paper, the value of good early planning can amount to $10 million or more.
