Aerzen Maschinenfabrik GmbH (Aerzen, Germany; www.aerzen.com) has commercialized the first rotary lobe compressor, the Delta Hybrid, which combines the technologies of both a rotary lobe blower and a screw compressor. This union reduces the energy consumption by up to 15% compared to conventional compressors, says the company. Whereas the Roots principle of isochoric compression is most suitable for...

Compressing carbon dioxide captured from power plants to 1,500–2,200 psia for pipeline transmission or underground injection is a challenge that requires eight stages or more, using conventional compressors. A compressor that promises to do the job in two stages, for 50–60% of the installed cost, is being developed by Ramgen Power Systems, Inc. (Bellevue, Wash.; www.ramgen.com). Ramgen has been...

Webinar: Heat Transfer Optimum Performance in Thermal Fluid Heating Systems: The importance of heat flux and film temperature Date: November 6, 2008 | Time: 11am EST In circulating thermal-fluid heating systems, the rate of heat transfer is typically controlled to maintain a desired outlet-temperature setpoint of the fluid. However, it is the temperature of the fluid film in contact with the heater walls...

Each compressed air system is typically composed of one or more compressors with a power source, control system, intake air filter, after cooler and separator, air receiver, air dryer, interconnecting piping and a distribution system to deliver air to points of application. Because the air leaving the compressor is generally saturated, any reduction in temperature will cause water to begin condensing...

Compressed air is often referred to as the fourth utility, and yet for an upstart business or process there is no commercial infrastructure that provides a core supply as exists with gas, electricity and water. When a need for compressed air is identified in planning and feasibility studies, it is necessary for the owners of the process or business to develop and maintain their own systems. Often the...

June 15, 2008
Compressed air is your most expensive utility. This is a fact that has been documented time and time again. It takes 7 to 8 hp of electricity to produce 1 hp in an airtool. In many plants, the compressed air system is the largest user of electricity. Yet, despite rising utility rates, compressed-air-system efficiency is frequently misunderstood or too often overlooked. Every plant or processing facility...
