Air Treatment

Compressed air contains contaminants such as dirt, water and oil which must be removed before use. ISO8573.1 specifies air quality classes for these contaminants. Humidity is expressed in terms of Pressure Dew Point (PDP). PDP is the temperature at which air is fully saturated with moisture, when the air temperature falls below this point further condensation will occur.
Desiccant dryers are commonly used to bring the pressure dewpoint well below freezing (commonly -40°F) in order to prevent moisture from precipitating in the compressed air system and production equipment.
Compressed air dryers are important items to consider when evaluating the efficiency of a typical compressed air system. One of the keys to optimal system operation is ensuring the air is only dried to the level required by the actual needs of the facility.
This article reviews two major processes in paper mills: compressed air quality and air compressor cooling.  The central air compressor room was expanded and relocated at the largest privately owned paper mill in Canada.  The compressor space was required by a plant expansion, which would occupy the original compressor space for increased production.
Compressed Air Best Practices spoke with the Parker PDF (Purification, Dehydration, and Filtration) Division.
The snack food facility is running with two normally separated compressed air production systems: the main plant system and the nitrogen system.
The next time you sit down for dinner, take a good look at your food. There’s a very good chance compressed air played an essential role in preparing your meal for consumption.
The NPE2009 international plastics showcase was held June 22-26 in Chicago’s McCormick Place. While attendance was down from NPE2006, the preliminary total of visitor registrations numbered 44,000. Sustainability and energy efficiency was a prominent topic in the booths of exhibitors. Manufacturers of compressed air and injection molding equipment had many developments with Sustainability to show the visitors to NPE2009.
Resin drying is a critical step in the manufacturing process of injection molding, extrusion molding and stretch blow molding.  Compressed air resin dryers are one of the most commonly used dryers in the plastics molding industry. Recent advancements in compressed air membrane-type resin dryers, have reduced the associated energy costs significantly.
Nuclear power plants produce electricity for people, business and industry.  Electricity is produced in a similar fashion as fossil fuel (i.e., coal, oil, etc.) power plants, using steam to drive a turbines which spin an electrical generator, producing the electricity. 
Industry standards serve a very important purpose for the end users of compressed air equipment.  If the standards are well written, they can help to promote the equipment that they govern, as long as the equipment manufacturers properly apply and promote the standards.
