SIM 2208 Pressure Control – Selective

SIM 2208 Selective Pressure Control Simulation shows a vertical closed pressure vessel being fed with a supply of nitrogen. The nitrogen exits the vessel through a single line with a valve controlling the flow.

About the Sim

Model Description

The flow from the vessel is controlled by a flow controller and the pressure in the vessel is controlled by a pressure controller

The output from these 2 controllers are high selected meaning the controller giving the larger output is the signal used. This means the controllers will maintain a minimum flow out from the vessel but will also protect against over pressure.

The feed to the vessel can be varied by introducing a second flow of gas to test the effect on the pressure control system.

Disturbances can be added to the upstream and downstream pressures of the system to allow realistic learning on how the control method responds to the type of disturbances found on a real plant.

The P&ID settings of the controller can be altered to improve the tuning of the controller for the various conditions that can be created.

The simulation includes exercise’s based around the tuning of the pressure control system.
