Abstract
Safety devices such as safety valves and rupture discs are crucial components in protecting chemical reactors from exothermic runaway reactions and overpressure scenarios. While traditional safety valves operate autonomously, controlled safety devices offer the potential for dynamic adjustments to optimize system performance. However, existing safety valves and controlled safety pressure relief systems (CSPRS) lack flexibility in a fixed relief pressure and stroke positions. This article introduces a new smart overpressure protection device (SmOP) with an adaptable safety device controlled through a combination of model predictive control and PID-control. Tested extensively in a high-pressure loop, the SmOP demonstrates rapid and precise control behavior, ensuring reactor safety as well increasing the efficiency. The control concept, based on model prediction followed by PID-correction, is validated through endurance tests and various opening conditions. Results indicate the SmOP's robustness against external disturbances and its potential for industrial applications. Future work includes developing a failsafe concept and laboratory tests with chemical reactions to further validate the SmOP's performance.
