Dynamics mode results for the U6 example simulation

The following curves are representative of the different cases mentioned in Dynamics mode for the U6 example simulation.

Scenario 1: Hot oil at 285°C

Details: Change the TC.SP value to 285°C at time 30 seconds.

You can view the results for this Scenario by reverting to the Dyn 2 snapshot.

Scenario 2: Hot oil at 200°C

Details: Change the TC.SP value to 200°C at time 30 seconds.

You can view the results for this Scenario by reverting to the Dyn 3 snapshot.

Scenario 3: E1 shutdown

Details: Close the E1 inlet valve, XV3, at time 30 seconds.

You can view the results for this Scenario by reverting to the Dyn 4 snapshot.

In this event, XV3 is closed to carry out maintenance of heat exchanger E1. The duties for the Fired Heater and heat exchanger E2 are affected, as shown by their duty profiles and their corresponding flow profiles in the following figures. In this case, E2 picks up some of the loss of heat exchange performed by E1, thus indicating a more negative value.
