What safety control interlocks should be considered in the amination process, and what control functions are essential?

In accordance with the requirements of Document No. 116 issued by the State Administration of Work Safety, the amination process is considered a hazardous process. The unit that requires close monitoring is the amination reactor; key parameters to monitor include the temperature and pressure inside the reactor, the stirring speed of the reactor, the flow rate of reactants, the ratio of the reactants used, and the oxygen content in the gas phase. The safety control requirements include: alarms and interlocks for temperature and pressure inside the reactor, proportional and interlocked control of the reaction materials, an emergency cooling system, a monitoring and interlocking system for gas-phase oxygen content, an emergency inert gas injection system, an emergency shutdown system, a safety relief system, and detectors for flammable and toxic substances. The appropriate control approach involves establishing a interconnection among the temperature and pressure in the amination reactor, as well as the mixing action within the reactor; the flow rate of the materials used in the amination process; and the inlet valve for the cooling water in the reactor’s jacket. An emergency shutdown system should also be installed. Safety devices: safety valves, rupture discs, check valves, emergency shut-off devices

Are there any others besides those specified in the \"List of Key Hazardous Chemical Processes Subject to Strict Regulation\"?
