Industry faces the threat of draconian demands from Congress as chemical plants remain an attractive targets for terrorism attacks, according to Mark Rosenzweig, editor in chief of Chemical Processing.
The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.
Carefully managing compressed air can save money. Compressed air is often overlooked in energy studies because many people do not fully understand compressed air equipment, their own system, or what it costs to produce compressed air power.

Nanotechnology is grabbing headlines these days and the growing prospects of its use is spurring increasing attention to safety issues. This article examines the worldwide reaction to burgeoning popularity of the technology and what safety concerns are legit.
Chemical processors face significant challenges in controlling fugitive emissions. The emissions escape from valves, compressors, pumps, piping components, etc. It is a difficult task, but necessary to avoid penalties and other liability.
Fine powders often need air injection to increase flow rates to an acceptable level. With entrained or injected air, powders flow like water, but when deaerated, the extremely low flow rate may be confused with a hang-up or arching condition.
