Abstract
This paper summarizes some key results obtained from an EPRI funded study the main objective of which was to investigate the principal economic and technical factors that influence the energy related investment strategy of industrial site operators. A case study approach utilizing three petrochemical processes was used in the project.
For the selected examples, for a fuel price of ) $3/MMBtu, pinch technology based energy conservation retrofits showed payback periods of less than 2 years. The work showed that the price of electricity that would make cogeneration economically unattractive can vary considerably from one process to another even in a given industrial sector. No generalization of cogeneration deferral rates was possible for the cases studied.
