KBC used refinery wide process and utility models to develop a holistic utility strategy. Using Pinch Technology, KBC identified opportunities in all licensed units, and were able to specify improvements before the licensors commenced development of Process Design Packages (PDPs).
The team adopted a highly electricity centric rather than steam centric utility design. In addition changes to column sequencing were proposed to dramatically reduce energy consumption in some units.
KBC significantly exceeded target savings with a 14% energy reduction in final design.
