Core Viewpoint - The Liaoning Provincial Emergency Management Department issued guidelines to accelerate the implementation of full-process automation in high-risk chemical processes, specifically chlorination, fluorination, diazotization, and peroxidation [1][2]. Group 1: Guidelines Overview - The guidelines apply to chemical enterprises engaged in the "four chemical processes" and focus on the full-process automation of existing facilities [1]. - Full-process automation includes both upstream processes (such as raw material handling) and downstream processes (including reaction, post-treatment, storage, and packaging) [1]. Group 2: Safety and Control Measures - The guidelines require the establishment of emergency shutdown functions independent of the basic process control system, particularly in areas where temperature and pressure exceed safe limits [2]. - Specific safety assessments, including HAZOP analysis, LOPA analysis, and SIL classification, must be conducted prior to the implementation of automation control systems [2]. Group 3: Process-Specific Requirements - The guidelines specify that the upstream processes for diazotization reactions must achieve automation control, particularly for configurations involving aniline and sodium nitrite with moisture content below 40% [2]. - High-level alarms and interlock systems must be implemented for dangerous chemical measuring tanks, and mechanical or automated modifications are required for operations involving chlorides, fluorides, and diazotization products [2].
