制氮机在化工行业的具体应用场景​

Petrochemical Field

Reaction Process Protection:

In many petrochemical reactions, such as catalytic cracking and hydrorefining, the high-temperature and high-pressure reaction conditions make the raw materials and products extremely susceptible to reaction with oxygen, leading to side reactions or even explosions. The nitrogen gas produced by the nitrogen generator is introduced into the reactor to create an oxygen-free inert environment, effectively preventing oxidation reactions, ensuring the smooth progress of the reaction, and improving product quality and yield.

Tank Nitrogen Blanketing:

The petrochemical production process requires the storage of large quantities of flammable liquid raw materials and products, such as crude oil, gasoline, and diesel. These liquids can volatilize during storage, producing flammable vapors that, when mixed with air, pose an explosion risk. By using a nitrogen generator to blanket the tanks—that is, filling the headspace of the tank with nitrogen—a layer of nitrogen protection is created, isolating the air from the liquid, suppressing the volatilization of flammable vapors, reducing the risk of explosion, and also reducing the oxidation and deterioration of the liquid.

Equipment and Pipeline Purging and Replacement:

During the construction, inspection, and maintenance of petrochemical plants, equipment and pipelines often contain residual flammable gases or other impurities. Before proceeding to the next operation, nitrogen must be used to purge and replace the equipment and pipelines, removing the flammable gases and impurities to ensure the safety of subsequent operations. For example, before plant maintenance, nitrogen is used to displace flammable gases from reactors and pipelines, reducing the oxygen content inside the equipment to a safe range to prevent explosions when opening the equipment for maintenance.

Fine Chemical Field

Reaction Environment Control:

Products from fine chemical production typically have high added value and extremely strict requirements for the production process. Many fine chemical reactions are highly sensitive to oxygen and moisture; even trace amounts of oxygen or moisture can cause side reactions, leading to decreased product purity, unstable quality, or even production failure. The nitrogen generator provides a pure nitrogen protective atmosphere for equipment such as reactors, centrifuges, and dryers, ensuring that the entire reaction process takes place in an oxygen-free and dry environment. Taking the production of pharmaceutical intermediates as an example, continuously introducing high-purity nitrogen during the reaction can effectively prevent the oxidation of raw materials and products, improving product yield and quality stability.

Material Storage and Packaging Protection:

Fine chemical products also require nitrogen protection during storage and packaging. Many fine chemical raw materials and products, such as easily polymerized monomers and deliquescent powders, are prone to deterioration due to reactions with oxygen and moisture in the air. On-site nitrogen generation using a nitrogen generator, nitrogen blanketing of storage containers, and nitrogen filling during product packaging can isolate the air, extending the shelf life and ensuring product quality.

Other Chemical Production Stages

Chemical Gas Manufacturing:

In the production of some chemical gases, nitrogen is used as a raw material or diluent. For example, in the production of ammonia, nitrogen and hydrogen react under high temperature and pressure with a catalyst to produce ammonia; in the preparation of certain special gases, nitrogen is used to dilute the reaction gas to control the reaction rate and product purity.

Pipeline Transportation:

For some corrosive, flammable, or explosive chemical materials, using nitrogen as a transport medium can effectively prevent reactions between the material and the pipeline, preventing pipeline corrosion and leakage, and also reducing safety risks during transportation. For example, when transporting liquid hydrocarbon substances, the pressure of nitrogen is used to transfer the material from one container to another, ensuring safe and reliable transportation.

Safety Protection:

In chemical production workshops, the nitrogen produced by the nitrogen generator can be used to create a safe explosion-proof environment. By appropriately deploying a nitrogen supply system in the workshop, when the concentration of flammable gases in the air is detected to exceed the limit or other dangerous situations occur, nitrogen is quickly released to reduce the oxygen concentration, bringing the concentration of flammable gases in the environment below the explosion limit, effectively preventing explosions and ensuring the safety of personnel and company property.

Benefits of Nitrogen Generators for the Chemical Industry

Safety Benefits

By providing an inert gas environment for chemical production, nitrogen generators greatly reduce the probability of safety incidents such as oxidation and explosions, creating a safe and stable production environment for chemical companies, ensuring the safety of employees and the sustainable development of the company.

Economic Benefits

Compared to purchasing bottled nitrogen or liquid nitrogen, on-site nitrogen generation using a nitrogen generator can significantly reduce gas procurement costs. Companies do not need to bear high transportation costs and deposits for bottled gas, and the cost advantage becomes more apparent as the production scale expands.

Nitrogen generators can adjust nitrogen output and purity in real time according to the actual needs of chemical production, avoiding production delays or resource waste due to insufficient or excessive nitrogen supply, improving production efficiency, and indirectly creating economic benefits for the company.

By using nitrogen generators to ensure the stability and quality of the chemical production process, the defect rate and scrap rate are reduced, production costs are lowered, product market competitiveness is improved, and companies can obtain more market share and profits.

Summary and Outlook

The widespread application of nitrogen generators in the chemical industry plays an indispensable role in various aspects, from reaction protection and material storage in the production process to safety protection, supporting the safe, efficient, and green development of the chemical industry. With the continuous development and technological progress of the chemical industry, higher demands are placed on the performance and reliability of nitrogen generators. In the future, nitrogen generators will develop towards intelligence, energy saving, miniaturization, and customization to meet the increasingly diverse needs of the chemical industry. At the same time, continuous innovation and breakthroughs in nitrogen generator technology will inject new vitality into the sustainable development of the chemical industry.
