2. • 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.
