Plant production is limited by feedstock processing. To determine if proposed process design changes will allow greater throughput, a high-fidelity dynamic simulation of the process is constructed using HYSYS. The engineer responsible for resolving the production limitation must determine whether the product specifications can be met using the original control strategy. To examine the control system's response to changes in feedstock, the engineer installs DeltaV Simulate onto his development computer with HYSYS simulation.
By assigning the current DeltaV control strategy used in the plant to his computer and configuring HYSYS to access the control I/O blocks, the engineer is able to simulate the dynamic response of his plant with the current control strategy. By introducing the expected feedstock changes into the process simulation, he determines that the current control strategy does a good job. However, the tuning of some loops will need to be changed. Tuning with InSight in the DeltaV Simulate environment with HYSYS providing the process simulation, he retunes the simulated control loops and establishes what the best tuning will be for the new process design.
