1. Incident Alert: Safety Risks in Traditional Batch Reactor Processes
On March 3, 2025, a bursting disc rupture in a reactor at LNSYZY Chemical Co., Ltd. caused toluene leakage and ignition. While no casualties occurred, this incident highlights inherent risks in traditional batch production methods. Recent chemical safety accidents in SD, XJ, and other regions underscore the urgent need to transition toward safer, more controllable technologies for handling high-temperature, high-pressure, and flammable materials like toluene.
2. Continuous Flow Technology: Building Safety Barriers for Hazardous Chemical Production
Addressing critical issues in traditional batch reactors—such as large material inventories, manual operation risks, and unstable pressure/temperature control—continuous flow production systems achieve inherent safety through these key features:
● Closed Continuous Operation Eliminates Leakage Risks
Continuous flow systems employ fully sealed microchannel designs, ensuring toluene and other materials remain in enclosed environments. Reaction volumes are reduced to 1/10–1/100 of traditional reactors, drastically minimizing leakage potential. Real-time pressure and temperature adjustments via smart sensors prevent overload scenarios.
● Precision Temperature Control & Rapid Response
Integrated heat-exchange modules and automated control systems enable millisecond-level temperature regulation, preventing localized overheating that could trigger decomposition or runaway reactions—critical for toluene nitration, sulfonation, and other highly exothermic processes.
● Automation Reduces Human Error
Fully automated control from feeding to reaction and discharge eliminates high-risk manual operations (e.g., sampling, reactor inspections). AI-powered anomaly detection ensures "zero-contact" production safety.
● Inherent Safety Design Minimizes Special Operations
Modular structures reduce maintenance frequency, while Clean-in-Place (CIP) technology avoids traditional hot work hazards, aligning with emergency regulators' "avoid non-essential hot work" mandates.
3. Industry Transformation: Leveraging Technology to Fulfill Safety Commitments
As chemical safety regulations intensify, continuous flow technology addresses policy requirements through:
● Compliance with Hazardous Chemical Safety Overhaul mandates for inherent safety upgrades in major hazard installations
● Support for "leadership oversight + smart monitoring" dual safeguards, enabling second-level response to abnormal conditions
● Full-process data traceability to meet online inspections and risk assessment needs
