What is the key technology of air separation equipment?

The key technology of air separation equipment is the technology of separating the mixed gas in the air into a single gas by physical means. Air separation equipment usually includes compression, cooling, membrane separation, adsorption, condensation and other technical units, through the combination and coordination of these units, to achieve effective separation and refining of air.

First of all, the compression technology of air separation equipment is the basis for the separation of gases in the air. By compressing the air to a certain pressure, the difference in density and solubility of different gases leads to the separation of gases, thus achieving the initial separation effect.

Secondly, cooling technology also plays an important role in air separation equipment. By lowering the temperature of the air, the different components of the gas mixture can condense or liquefy, thus achieving further separation. Cooling technology is often combined with evaporation technology to achieve the evaporation and cooling process of the gas to further improve the purity of the gas.

In addition, membrane separation technology is also one of the key technologies in air separation equipment. Membrane separation technology can effectively screen and separate gases according to the permeability and selectivity of different gases by selecting appropriate membrane materials and membrane structures. Membrane separation technology has the advantages of simple process, low energy consumption and convenient operation, and is widely used in air separation equipment.

In addition, adsorption and condensation technology is also commonly used in air separation equipment separation technology. Adsorption technology through the selection of suitable adsorbent, using different gases on the adsorbent adsorption performance differences, to achieve efficient separation of gases. The condensation technology condenses the gas into liquid by reducing the temperature of the gas and realizes the condensation separation of the gas.

In summary, the key technologies of air separation equipment include compression, cooling, membrane separation, adsorption, condensation and other technical units, through the combination and cooperation of these technologies, to achieve efficient separation and purification of mixed gases in the air. With the continuous development and progress of science and technology, the key technologies of air separation equipment are also constantly innovative and improved, providing more possibilities and opportunities for the development of the field of air separation.
