Which units can do safety risk assessment of fine chemical reactions?

At present, the production of fine chemicals is mainly intermittent and semi-intermittent, with complex and changeable processes, low automatic control level and many on-site operators. Some enterprises have insufficient knowledge of the safety risks of reaction and unscientific understanding of the key points of process control, which may easily lead to fire, explosion and poisoning accidents due to out-of-control reaction, resulting in mass casualties.

Where are the risks of fine chemical reactions?

(1) Temperature: The harm of temperature itself is limited.

(2) Pressure: The influence of any temperature rise on the system is more important. There are three potential sources of overpressure: ① anger in normal process; (2) Vapor pressure effect (such as the result of heat release in normal process); (3) When the temperature rises, the heat from normal process leads to decomposition reaction (leading to gas and/or steam effect).

In 20 17, the State Administration of Work Safety issued "Guiding Opinions on Strengthening Safety Risk Assessment of Fine Chemical Reactions", which clearly required that the raw materials, intermediates and products involved in chemical reactions should be tested for thermal stability, and the chemical reaction process should be analyzed by thermodynamics and kinetics, and the reaction risk level should be evaluated according to the reaction heat, adiabatic temperature rise and other parameters. The possibility of out-of-control reaction should be evaluated according to the parameters such as the arrival time of the maximum reaction rate, and multi-factor risk assessment should be carried out in combination with relevant reaction temperature parameters.

Strengthen the safety risk assessment of fine chemical reaction

Through the safety risk assessment of fine chemical reaction, the degree of danger in the reaction process is determined, so as to improve the design of safety facilities and risk control measures, improve the intrinsic safety level of enterprises and effectively prevent accidents.

Safety risk assessment unit of fine chemical reaction;

Zhongke detection

It can provide chemical reaction safety risk assessment services, and provide research and assessment of reactants and reaction risks for enterprises and institutions in the fields of pharmacy, drug research and development, fine chemicals, new energy and new materials.

The out-of-control reaction in fine chemical production is an important reason for the accident. It is of great significance to carry out the safety risk assessment of fine chemical reaction, determine the risk level and take effective control measures to ensure the safe production of enterprises. Carrying out risk assessment of reaction safety is also an inevitable requirement for enterprises to obtain safety production information, implement safety management of chemical process and strengthen safety production management of enterprises.
