• The utilities are a set of tools, which interact with a process by providing additional information or analysis of streams or operations.

• In HYSYS, utilities become a permanent part of the flowsheet and are calculated automatically when appropriate.

• Utilities can also be used as target objects for “Adjust” operations.
