The new process's operation method and safety verification

Problem: This device is being constructed for the first time on an industrial scale. The process is complex and risky, and there is a lack of operational experience with actual devices. On one hand, there are no similar devices available for trainees to practice operating on. On the other hand, for the first industrialized device, there is no experience to refer to regarding whether the operation methods are reasonable and safe, whether the control system such as sequential control can function normally, and how to handle abnormal situations if they occur. For example, if the reagent activity is very strong, improper operation can easily lead to runaway temperature and overpressure accidents.

Solution: During the design phase, a full-process dynamic model including strict kinetic reactions and separation processes was established. Special emphasis was placed on conducting rigorous and multi-condition tests on the reactor cycle replacement agent control system with extremely high risks. The reliability of the venting system was analyzed and studied, and based on this model, the OTS system was established. Operators received training on start-up and shutdown in this system. Benefits: Based on the simulation results, the research focused on the development of the reactor agent replacement rotation control system. A safe and reliable control sequence was determined, and it was thoroughly verified and tested through dynamic validation and testing. The logic, operation methods, and precautions of this control program were finally refined and completed. Any identified problems and deficiencies were modified and verified. These studies have significant importance and value in ensuring the safety and reliability of the device's operation and running. They are a typical case of "the strict mechanism-based OTS not being only a training system".
