Introduction To Carbon Molecular Sieves
In the industrial production process, the purity of nitrogen is directly related to the product quality of the enterprise and the stability of the production process. The common nitrogen making equipment is the nitrogen generator. How can the purity of nitrogen be guaranteed during operation? For this question, the carbon molecular sieve manufacturer will give a brief introduction to this aspect to the majority of users.
The source is extremely important, that is, the quality of the raw material air. Generally, the air passes through the inside of the nitrogen generator, and then passes through high-efficiency filters and drying equipment to remove dust, moisture and other impurities in the air, so as to ensure the purity of the raw material air.
Next, we have to go to the core component of the nitrogen generator, which is the carbon molecular sieve. As the core gas adsorption and separation filter material of the nitrogen generator, the quality of the carbon molecular sieve is related to the purity, total amount and service life of the final nitrogen produced. Therefore, it is particularly important to choose a carbon molecular sieve with excellent performance and reliable quality.
The operating parameter setting of the nitrogen generator is also particular, and it can be said that the influence on the purity of nitrogen is also very large. It is mainly to optimize the nitrogen generation process and improve the purity of nitrogen by adjusting parameters such as pressure and temperature.
PSA Nitrogen Production Principle
PSA nitrogen generator mainly uses physical adsorption to separate nitrogen and oxygen in the air, mainly based on the difference in the adsorption capacity of carbon molecular sieves for oxygen, nitrogen and other gases on the surface of molecular sieves. That is, when compressed air passes through an adsorption tower filled with carbon molecular sieves, impurities such as oxygen, carbon dioxide, and water vapor will be adsorbed on the surface of the molecular sieve. Due to the weak adsorption capacity of nitrogen, it passes directly through the molecular sieve, thereby obtaining the separation of nitrogen.
In the actual operation process, PSA nitrogen generators are generally equipped with two or more adsorption towers for alternating use. When one adsorption tower is in an adsorption state, the other adsorption tower is in a desorption state. The desorption process is to desorb the adsorbed impurities by reducing the pressure in the adsorption tower, so that the molecular sieve can be used to prepare for the next round of adsorption process.
