Description
Compressed air refers to air compressed by an external force. After the air is pressurized by a fan to the pressure required by the process and undergoes preliminary pretreatment, it then directly enters the adsorption tower, where components such as H2O and N2 are successively adsorbed by the adsorbent, and oxygen-enriched output can be obtained immediately. The production process of compressed air and oxygen includes the collection and preparation of air, the filtration and purification of air to remove impurities and moisture, and also the energy and material consumption for the operation of the compressed air system (such as air compressors); the dataset is formed by merging data from multiple sources.

Process Description
Compressed air is air compressed by external force. Air is compressible. The air after the air compressor does mechanical work to reduce its volume and increase its pressure is called compressed air. Compressed air is an important source of power. The air is pressurized by the fan to the pressure required by the process and undergoes a preliminary pretreatment process, and then directly enters the adsorption tower. The H2O, N2 and other components are adsorbed sequentially after passing through the adsorbent, and oxygen-enriched output can be obtained immediately. Pressure swing adsorption oxygen production technology is a gas separation method based on the principle of physical adsorption. This technology uses a specific adsorbent to adsorb impurities such as nitrogen under pressure, which has a much greater adsorption capacity than oxygen, thereby achieving the separation and purification of oxygen. During the adsorption process, as the pressure changes, the amount of nitrogen adsorbed by the adsorbent will also change, thereby achieving continuous production of oxygen.
