All atmospheric air contains some amount of water vapor. When air is compressed, the water concentration increases. To avoid future problems in the compressor installation, the compressed air needs to be treated. In this article we are talking about adsorption air drying.
What is adsorption air drying?
Adsorption air drying is a chemical process in which water vapor is bound to absorption material. The absorption material can either be a solid or liquid. Sodium chloride and sulfuric acid are frequently used, which means that the possibility of corrosion must be taken into consideration. This method is unusual and involves high consumption of absorbent materials. The dew point is only lowered to a limited extent.
