Prevent the advancement of the gate to reduce the flash explosion accident
Experts have emphasized the critical importance of safety in the hydrogen peroxide production process, highlighting that proactive measures and advanced risk management are essential to prevent accidents. At the recent Peroxide Industry Symposium, industry leaders discussed strategies for ensuring safe and stable operations throughout the production cycle.
One of the primary concerns in hydrogen peroxide manufacturing is the risk of flash explosions, particularly in equipment such as tanks, oxidation towers, and pipelines. Many incidents have been linked to static electricity, which can act as an ignition source. To mitigate this, experts recommend implementing strict electrostatic control measures, including proper grounding of equipment and pipelines to eliminate potential hazards before they escalate.
Managing raw materials is also a crucial step in maintaining safety. Engineers suggest that manufacturers should carefully evaluate the quality and flash point of heavy aromatics used in the process. By selecting high-flash-point materials, companies can reduce the likelihood of dangerous reactions at the source. Additionally, resin quality plays a significant role in the purification stage. Resins must be regularly monitored and regenerated to avoid degradation, which could lead to unsafe conditions.
Temperature control is another key factor in preventing accidents. Experts note that over 95% of hydrogen peroxide-related explosions occur when temperatures exceed 60°C. During startup or shutdown phases, where process parameters fluctuate significantly, maintaining lower temperatures (below 40°C) is vital. Even if static electricity is present, it will not trigger an explosion if the temperature remains below the flammable range.
Pressure monitoring is equally important. If pressure exceeds 30% of the equipment’s design limit, immediate action is required to prevent catastrophic failure. Operators must remain vigilant and respond swiftly to any signs of pressure buildup.
Feed concentration is also a critical parameter. High-concentration hydrogen peroxide increases the risk of system instability, especially during evaporation and distillation. When feed concentrations reach 40–46%, the system becomes more vulnerable to impurities and operational challenges. Proper purification of incoming materials is essential to remove contaminants like iron, tin, and sulfate, which can accumulate and compromise safety.
In summary, the safe production of hydrogen peroxide requires a comprehensive approach that includes material management, precise temperature and pressure control, and careful attention to feed concentration. These measures, when implemented effectively, can significantly reduce the risk of accidents and ensure the long-term stability of the production process.
