Carbon molecular sieves serve as the core adsorption material in nitrogen generators. The method of replacing them is crucial for the stability and lifespan of the equipment. In the operation of PSA nitrogen generators, the replacement of carbon molecular sieves is extremely important. It is the core for nitrogen separation. It is constantly contaminated by impurities, resulting in clogging of micropores and even pulverization, which can damage the structure and adsorption properties. This leads to a significant drop in nitrogen purity, failing to meet the high-purity nitrogen requirements of multiple industries and affecting product quality.

During nitrogen production, due to the frequent adsorption and desorption processes, the carbon molecular sieve structure becomes fatigued, the micropores deform, and the adsorption and selective adsorption capabilities decrease. This leads to an increase in the energy consumption of the nitrogen production machine, an increase in costs, and may also cause the associated components to overwork and have more failures, threatening the continuity and stability of production. Therefore, timely replacement of the carbon molecular sieve is an indispensable key measure for ensuring the efficient and stable operation of the nitrogen production machine, achieving nitrogen quality standards, reducing costs, and maintaining production order.

The prolonged use of carbon molecular sieves not only significantly reduces the efficiency of the gas separation process, but also causes the powdering of the molecular sieves, which leads to an increase in equipment resistance, higher maintenance costs and an increased risk of system failure.

The original factory service of SinceGas adopts a proven professional replacement process and control procedures. It is operated by professional service personnel and carried out using professional tools and vibration platforms. This ensures that the carbon molecular sieves in the adsorption tower are evenly and tightly packed without any dead corners, significantly reducing the gaps between the molecular sieves and effectively controlling the powdering phenomenon caused by the collision of the molecular sieves with each other. This guarantees that the equipment after replacing the carbon molecular sieves can achieve the performance parameters and service life as at the time of its initial manufacture.
