This paper describes the application of KBC's Strategic Energy Review (SER) at the Chevron Phillips Chemical Company LP (CPChem) site in Port Arthur, Texas. The full SER program combines benchmarking, operational reviews and Pinch analysis with a systematic Total Site approach to define a complete spectrum of energy benefits ranging from in-process improvements to the optimization of the site-wide utility system.

New opportunities arising from the SER are combined with projects already under consideration by CPChem into a single energy improvement RoadMap which considers the strategic decisions for energy improvement and the interactions between the proposed projects to define a coherent forward implementation and investment plan.

Projects recommended for rapid implementation in a forthcoming turnaround significantly reduced energy consumption while achieving an overall payback period of one year. Medium-term investment opportunities then more than doubled the total energy savings with an incremental payback of less than two years.
