Summary for the U4 example simulation

An existing cooling water network supplies cooling water to sixteen heat exchangers in a chemical plant. After the heat exchangers, the cooling water network returns the cooling water to a cooling tower at 15 psia.

The objective of this simulation is to:

• Confirm that pipe sizes maintain water velocities between minimum and maximum requirements.

• Determine the required pressure for cooling water pump selection.

• Determine the actual flow rates distribution compared to process requirements

• Determine the total water flow if only one of two available pumps is operating.

The following figure shows the schematic diagram of the Cooling Water Network system, as modeled in AVEVA Process Simulation.
