To ensure the safety of the chemical manufacturing process, comprehensive measures need to be taken from multiple dimensions such as process design, equipment management, operating specifications, and risk control. The specific implementation framework is as follows:
Select safe raw materials and process routes
Prioritize the use of low-toxic, stable raw materials with mild reaction conditions to reduce the storage and use of hazardous substances.
Optimize the process route to avoid high temperature, high pressure or violent reaction conditions to reduce the risk of loss of control.
Strict parameter control
Precisely control key parameters such as reaction temperature, pressure, and material ratio, set up an automatic interlocking system, monitor abnormalities in real time and trigger emergency shutdown.
Configure a dual cooling system (such as ice bath, circulating water) for exothermic reactions to prevent heat accumulation.
Equipment selection and maintenance
Select corrosion-resistant, high temperature/high pressure resistant materials (such as stainless steel, special alloys) to manufacture reaction vessels and pipelines.
Perform non-destructive testing of equipment (such as ultrasonic testing) regularly to check for fatigue, corrosion or structural defects.
Install pressure relief valves, flame arresters and explosion-proof membranes to prevent pressure or flammable gas accumulation from causing explosions.
Equipped with anti-static grounding devices to prevent static sparks from igniting materials during feeding or transportation.
Standardized operation procedures
Develop detailed operating procedures (SOPs) covering the order of feeding, emergency disposal steps, etc. to ensure traceability of operations.
Use inert gas protection (such as nitrogen) when feeding to prevent flammable substances from contacting the air.
Training and assessment
Carry out safety training regularly to strengthen employees' skills in chemical properties, use of protective equipment and emergency response to leaks.
Improve team collaborative emergency response capabilities through simulation exercises (such as fire and leak scenarios).
Real-time monitoring and early warning
Deploy online monitoring systems (such as pH value, COD, and flammable gas concentrations) and combine AI algorithms to predict potential risks.
Establish a "red, yellow, and green" three-level early warning mechanism and link sound and light alarm devices.
Emergency Plan and Resource Reserve
Develop an emergency plan for accidents, clarify evacuation routes, first aid measures and external rescue docking procedures.
Emergency supplies (such as neutralizers, adsorbent sand, and chemical protective clothing) are always available on site, and their effectiveness is checked regularly.
Build a safety culture.
Encourage employees to proactively report hidden dangers, establish anonymous feedback channels and reward mechanisms.
Management regularly participates in safety inspections to strengthen safety responsibility awareness.
Compliance with regulations and standards
Strictly comply with national and industry safety standards (such as OSHA, ISO 45001), and regularly update compliance documents.
Commission a third-party organization to conduct safety audits to ensure continuous improvement of the management system.
Through the above systematic measures, the safety risks in the chemical manufacturing process can be significantly reduced, and the transition from "passive defense" to "intrinsic safety" can be achieved.
