Abstract
Key
performance indicators for process operations include economic, energy, and
sustainability metrics. The relative importance of these metrics varies from
plant to plant. Some metrics conflict
with each other, as, for example, sustainability and profitability. Authors discuss the current plant environment
and how various metrics can be aligned by focusing on energy efficiency.
Since power-steam systems are the major energy drivers for most
plants, they discuss possible operational changes that could improve energy
efficiency. They also discuss the role
of process control.
