Implementation of AQ 3062-2025 standard for safety management of fine chemical enterprises, and selection of oxygen content detection for reaction kettle centrifuge.

In production environments involving reaction vessels such as reactors and centrifuges in chemical and pharmaceutical industries, safety is the lifeline. The AQ 3062-2025 "Safety Management Specification for Fine Chemical Enterprises" issued by the Ministry of Emergency Management provides technical guidance for the construction of safety risk monitoring and early warning systems for enterprises, and the standard puts forward clear requirements for the control of oxygen concentration that may cause danger in the process.

Norco Instruments has been deeply involved in the field of gas analysis for nearly 20 years, accumulating a large number of on-site application cases and experience in oxygen content detection of reaction vessels in chemical and pharmaceutical industries.

The core of AQ 3062-2025 standard:

The core of AQ 3062-2025 standard is to build an integrated security system that includes monitoring, early warning, and disposal. The monitoring of oxygen concentration plays an important role.

Explosion prevention (inerting protection process): In containers, reactors, and pipelines, inert gases such as nitrogen are usually introduced to prevent the formation of explosive environments by mixing combustible gases or dust with air. At this point, real-time and accurate monitoring of oxygen concentration is crucial. The standard requires strict control of oxygen concentration below the explosive limit (usually below 2% to 5% oxygen volume fraction, depending on the process) to ensure that the environment is always in a safe state.

Typical application scenarios for oxygen content detection in reaction vessels and centrifuges:

Inert protection in the petrochemical industry: In the nitrogen sealing system of flammable liquid storage tanks such as benzene, alcohols, and olefins, the oxygen content in the sealing gas is continuously monitored to ensure that the atmosphere inside the tank is always in a non explosive state.

Safety monitoring in the production process of chemicals: In processes involving oxidation reactions, strict control of the oxygen concentration in the reactor is necessary to prevent peroxide from causing uncontrolled reactions or the accumulation of by-products leading to explosions.

Coal chemical and metallurgical industry: Monitor environmental oxygen concentration and prevent dust explosions in places such as gas cabinets, coal mill systems, and powder metallurgy sintering furnaces.

Safety is the first priority, and the rest is the last zero. Oxygen analyzers are not only measuring instruments, but also a core part of implementing the AQ 3062-2025 standard and building an intelligent safety warning system for enterprises. By providing accurate, reliable, and timely oxygen concentration data, it helps companies move the safety risk control checkpoint forward, shifting from passive disposal to active warning, ultimately achieving intrinsic safety and efficient operation of the production process. Choosing safety monitoring equipment that meets high standards is the most solid commitment to the assets of the enterprise and the lives of its employees.
