How can Compression be used to Dry Air?
Air compression suggests a method of reducing moisture content in air. As air is compressed, partial pressure of the water vapour in the water gas mixture rises to the point where moisture can be condensed from the air at a higher temperature. This approach is some times quite practical for very small volumes of air but the cost of compressed air equipment, BHP requirement and the amount of cooling water required for after-cooling makes it very impractical for large volumes of air.
