Optimizing steam equipment loadings

As a recap, we have identified three changes for the same steam system

Therefore, a utility optimizer could determine the most efficient and economic operation to supply energy to satisfy process demand. There are several major options to achieve this overall goal including driver selection, utility equipment loading allocation, steam head pressure control, steam letdown rate minimization, power generation versus purchasing, and contract management.
