Industrial Utility Efficiency    

Compressor Controls

Load-sharing is an important part of a multiple centrifugal-compressor master control system. It minimizes blow-off based on the available turn-down. In addition, remote start-stop saves more energy if load floats between different ranges. Finally, adding a screw compressor and implementing a hybrid control system might save the most energy and provide the best back-up. In any case, a well-instrumented system allows engineers and operators to assess, optimize and tune the system.
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.
The primary objective of this case study is to illustrate the process in which industrial facilities can qualify for energy incentives on projects that reduce the energy usage of their compressed air system.
Reducing energy costs and pollution emissions involves many areas within an industrial facility.  My studies have found seven (7) key (or common) areas where low cost practical projects can be implemented.  Combined, these projects provide savings exceeding 10% of the annual energy spend with an average payback of less than one year.
How do you test a 747 engine to ensure reliability once it’s airborne at 600 miles an hour?
Compressed Air Best Practices Magazine interviewed Sid Van der Meer (President) and Terry Nickel (Office Manager) of the Northwest Equipment Company.
Compressed Air Best Practices spoke with Jay Hedges (General Manager) of Mattei Compressors.
A four thousand, five hundred and fifty pound (4550 lbs.) race car is running at 170 mph and facing wind resistance of 150 mph. The car then enters a curve creating a three-degree “yaw” (the change in angle from the direction the car is headed and the airstream).  The car struggles to maintain speed as the yaw changes and the dynamic downforce load on the car changes.  Suddenly, the driver-less car comes to a stop on the stainless-steel track...
