Nitrogen generator for chemical industry

In the chemical industry, nitrogen plays a critical role in various processes, from inerting and blanketing to purging and acting as a carrier gas. A chemical nitrogen generator is an on-site device that produces nitrogen, providing a reliable and cost-effective solution for high-purity nitrogen supply.
Functionality Our chemical nitrogen generators harness advanced technologies such as Pressure Swing Adsorption (PSA) or membrane separation to extract nitrogen directly from the air. This process ensures a continuous supply of nitrogen that meets the stringent purity requirements necessary for chemical processes.

Advantages
On-Site Production With an on-site nitrogen generator, chemical plants can produce nitrogen as needed, reducing dependency on deliveries and storage of nitrogen bottles or bulk liquid nitrogen.
Cost-Effectiveness Generating nitrogen on-site eliminates recurring costs associated with nitrogen procurement and can lead to significant savings over time.
Reliability A chemical nitrogen generator ensures a stable and uninterrupted nitrogen supply, which is crucial for maintaining the efficiency and continuity of chemical production processes.
Safety By providing high-purity nitrogen, our generators contribute to a safer working environment, reducing the risks associated with oxygen exposure in chemical reactions.

Process flow

The air compressor compresses the raw air into high-pressure air, sends it to the air buffer tank to stabilize the pressure, and then further removes moisture, oil mist, etc. through the filter, and freezes and dehydrates through the refrigerated dryer to remove a large amount of moisture, and then enters the third stage. The filter further filters harmful substances, and then the clean compressed air enters from the bottom of the adsorption tower. After the air flow is diffused through the air diffusion device (universal spiral or porcelain ball), it evenly enters the adsorption tower for oxygen and nitrogen adsorption and separation, and then exits from the outlet end. The nitrogen flows out and enters the nitrogen storage tank. This nitrogen production process takes about 1 minute. Afterwards, through pressure equalization and pressure reduction (to normal pressure), the adsorbed impurity components (mainly oxygen) are removed, and the regeneration of the adsorbent is completed. The two adsorption towers operate in alternating cycles, continuously feeding raw air, and continuously producing qualified nitrogen.

Application

1. Inert Protection Chemical reactions that are sensitive to oxygen require an oxygen-free or low-oxygen environment to prevent the influence of oxygen on the reaction products. Nitrogen generators provide high-purity nitrogen for inert protection, ensuring the stability of the reaction process and the purity of the end product.

2. Coating Protection Materials that are prone to oxidation or affected by moisture during storage and transportation benefit from a nitrogen-rich environment. Nitrogen generators supply high-purity nitrogen for coating and protection, which extends the shelf life and enhances the stability of these materials.

3. Atmosphere Control Controlling the atmospheric composition within reaction vessels or equipment is essential for achieving specific reaction conditions in some chemical processes. Nitrogen generators can provide customized nitrogen atmospheres to adjust the reaction environment and facilitate chemical reactions.

4. Gas Chromatography Gas chromatography is a prevalent analytical technique in chemical laboratories that requires high-purity nitrogen as a carrier gas. Nitrogen generators are capable of supplying nitrogen that meets the stringent purity requirements necessary for accurate and reliable gas chromatography analysis.

5. Solvent Evaporation Protection In laboratories or production processes, volatile solvents may need to be evaporated in an oxygen-free or low-oxygen environment to prevent oxidation or other unwanted reactions. Nitrogen generators provide the necessary inert atmosphere for the safe and controlled evaporation of these solvents.

Nitrogen generators play a vital role in the chemical industry, offering a range of applications including inert protection, coating protection, atmosphere control, gas chromatography analysis, and solvent evaporation protection. These generators provide an essential nitrogen supply and protection, ensuring the safety, quality, and efficiency of chemical production processes.
