Jiangsu: Focus on 7 aspects to improve the intrinsic safety level of nitrification enterprises

The on-site control room or central control room of the nitrification plant should be equipped with a monitoring and early warning system to realize automatic early warning and send the early warning information to relevant personnel in time
.
The emergency operation information that occurs during the production process should be reported to the post operator in time
.

Actively implement process improvements to effectively reduce safety risks

In principle, the newly renovated and expanded nitrification equipment adopts continuous nitrification production processes such as microchannels; the whole process promotes the application of mechanized and automated production equipment and facilities to minimize the number of on-site operators
.
The newly-built nitrification device shall be arranged separately, and shall not be mixed with other devices or arranged in the same workshop.
The fire separation distance from surrounding buildings (structures) shall at least meet the requirements of the "Design Fire Protection Standards for Petrochemical Enterprises" (GB50160).
Fixed operating positions are set up in the production equipment
.

If the nitrification product of the newly renovated and expanded nitrification unit contains flammable organic solvents, it is strictly forbidden to use open or semi-open separation facilities, and the separation of flammable organic solvents should be realized under the condition of nitrogen seal
.
The separated materials should be transferred to the next process in time, the intermediate nitrification products and products should be put into the warehouse (tank) in time, and the amount of materials temporarily stored in the nitrification device should be strictly controlled; the nitrification waste storage site should not exceed the designed amount, and the storage amount should be reduced as much as possible , To prevent the spillover of safety risks
.

Nitrification enterprises should actively adopt new processes and technologies, implement online volume reduction technology transformation of hazardous chemicals in the nitrification production process, and minimize the storage of raw materials, intermediate and final products with explosive hazardous characteristics
.
Improve the solid-liquid separation process of nitrification products to realize automatic control and reduce the risk of manual operation
.

Strengthen safety education and training and comprehensively improve the quality of employees

The main person in charge and the person in charge of production, technology, safety and full-time safety management personnel newly hired by the nitrification enterprise must have a college degree or above in chemistry, chemical industry, safety and other related majors or an intermediate or above professional title in the chemical industry.
Newly hired operators Must have a high school degree or above or a chemical secondary or higher level of vocational education.
Newly recruited operators of production equipment and storage facilities involving explosive hazardous chemicals must have a college degree or above in chemical engineering.
Existing personnel who do not meet the above requirements The personnel should reach the corresponding level by the end of 2021
.

The nitrification equipment involved in raw material processing, reaction and separation positions internal operators, external operators and monitors should obtain the special operation qualification certificate of the nitrification process, and those involved in the collection, storage, and transshipment of nitrification waste within the enterprise shall not use labor dispatch personnel
.

Revise and improve emergency plans to improve emergency response capabilities

Comprehensively identify the various dangerous and hazardous factors in the nitrification plant, revise and improve the emergency plan for production safety accidents of the enterprise, prepare special plans for fire and explosion of the nitrification plant, on-site disposal plans and post emergency response cards, equipped with emergency rescue facilities and equipment, and carry out emergency emergencies on a regular basis Training and actual combat drills enhance the emergency response capabilities of enterprises
