Nitrogen Purification System With Automatic Alarm Function Ensures The Quality And Purity Of Gas Production

Working Principle Description:

Nitrogen Purification: Nitrogen purification is the process of removing hydrogen and oxygen impurities using an adsorbent, typically a specialized molecular sieve or activated carbon. The gas mixture enters the nitrogen purification device and passes through an adsorbent bed. Hydrogen and oxygen are adsorbed on the adsorbent, while nitrogen passes through, achieving gas separation.

Hydrogenation: In the nitrogen purification process, hydrogenation involves adding a certain amount of hydrogen to the gas. This is because certain adsorbents have a strong affinity for hydrogen, allowing for more effective removal of oxygen. Hydrogenation helps enhance the effectiveness of nitrogen purification and ensures the production of high-purity nitrogen.

Deoxygenation: Deoxygenation in the nitrogen purification with hydrogenation process refers to the removal of oxygen from the gas. Oxygen is adsorbed on the adsorbent and undergoes a chemical reaction with active sites on the adsorbent. Through appropriate hydrogenation and adsorbent selection, efficient removal of oxygen is achieved.

Regeneration Cycle: Over time, the adsorbent becomes saturated and needs to be regenerated to restore its adsorption capacity. A common method is a cyclic process of desorption and regeneration. In the desorption phase, hydrogen and oxygen on the adsorbent are released, making the adsorbent available for nitrogen purification again.

Product Advantages:

Fault diagnosis and alarms: The automatic control system includes fault diagnosis and alarm functions, capable of promptly detecting and responding to potential issues. In case of abnormal conditions, the system issues alerts and takes appropriate measures to ensure the safe operation of the equipment and maintain nitrogen gas purity.

Quality Assurance: The automatic alarm function continuously monitors the nitrogen purification process and detects any deviations or abnormalities. This helps in maintaining consistent quality and purity of the produced gas. If any issues arise, such as a drop in purity or pressure, the alarm system promptly alerts the operators, allowing them to take immediate corrective actions.

Early Detection of Problems: The automatic alarm function is designed to detect issues at their early stages. For example, it can identify fluctuations in gas flow rate, pressure, or impurity levels. By alerting the operators promptly, potential problems can be addressed before they escalate, minimizing downtime and ensuring continuous production.
