Nitrogen Generator Technology Principle

A Pressure Swing Adsorption (PSA) nitrogen generator uses carbon molecular sieve as an adsorbent. It works on the principle of pressure adsorption and depressurization desorption to adsorb oxygen from the air and separate nitrogen. The adsorption characteristics of carbon molecular sieve for O2 and N2 are such that with increasing adsorption pressure, the adsorption amounts of O2 and N2 both increase, but the increase in O2 adsorption is greater.

Nitrogen Generator Technology Principle

Pressure swing adsorption (PSA) nitrogen generators use carbon molecular sieves as adsorbents. They separate nitrogen from air by adsorbing oxygen under pressure and desorbing it under reduced pressure. The adsorption characteristics of carbon molecular sieves for O2 and N2 are such that as the adsorption pressure increases, the adsorption amounts of both O2 and N2 increase, but the increase in O2 adsorption is greater. PSA cycles are short, and the adsorption of O2 and N2 is far from equilibrium. Therefore, the difference in the diffusion rates of O2 and N2 causes the adsorption amount of O2 to greatly exceed that of N2 in a short time. PSA nitrogen generation utilizes the adsorption characteristics of carbon molecular sieves, employing a cycle of pressure adsorption and pressure reduction desorption. Compressed air is alternately introduced into two adsorption towers to achieve air separation and continuously produce product nitrogen. We provide comprehensive pre-sales, in-sales, and after-sales services, including procurement, maintenance and repair services, and sales of spare parts. If you have any questions about the technical principles of nitrogen generators, please feel free to contact our company for more information.

Application of PSA pressure swing adsorption nitrogen generators in SMT welding

In recent years, with the increasing demand for the quality of welding products and the increasingly stringent national environmental protection requirements, lead-free welding has become widely popular. Inert nitrogen welding has been favored for its ability to improve product quality. Although the purchase of nitrogen atmosphere requires a certain amount of investment, it is much lower than the cost of environmental protection and rework due to welding defects. Therefore, the role of inert nitrogen atmosphere in SMT welding is increasingly valued and will gradually be accepted and widely used. However, the cost of using nitrogen depends largely on the flow rate, operating hours, reflow oven structure, and production process, and the choice of nitrogen source is even more important.
