Dew point is simply the temperature to which air must be cooled for the water vapor within to condense into dew or frost. At any temperature, there is a maximum amount of water vapor that the air can hold. This maximum amount is called the water vapor saturation pressure. If more water vapor is added beyond this point, it will result in condensation.

Tate & Lyle’s sustainability actions involve countless initiatives worldwide to minimize its environmental impact by reducing emissions and using water sustainably. Whether it’s the use of a low-pressure blower instead of a high-pressure compressed air system to save energy, or a $75 million natural gas-fired Combined Heat and Power (CHP) system to replace coal as a power source at its corn wet mill in Lafayette, Indiana, Tate & Lyle is on a mission to protect the planet.

The foundation of any purification system is its filtration and of the ten main contaminants found in a compressed air system, filtration is responsible for the treatment of nine of them. Coalescing filters are the most important piece of purification equipment as they reduce six of the ten contaminants and a look in any air compressor room will find a pair of coalescing filters (backed up with dry particulate and oil vapor removal filters).

In the field of externally heated adsorption dryers there is a large variety of different systems on the market offering substantial flexibility in terms of process flows, dew points and energy demand. Often, economic parameters and project-specific requirements ultimately define the individual user-specific solution. This article discusses the basic types of desiccants used in compressed air dryers.
