The System Assessment
Oil & Gas
Compressed Air Best Practices® Magazine spoke with Mark Shedd, Head of Oil-free Air, Aggreko Rental Solutions - There are two distinct compressed air systems in a refinery or petrochemical environment: plant air and instrument air systems. Instrument air systems are almost always 100% oil-free air compressors on both the permanent and temporary systems. The demand for compressed air purity, in instrument air systems, is so high that the permanent install back-up system is usually nitrogen.
Compressed Air Best Practices® (CABP) Magazine and the Compressed Air and Gas Institute (CAGI) cooperate to provide readers with educational materials, updates on standards and information on other CAGI initiatives. CABP recently caught up with Rick Stasyshan, Technical Director for the Compressed Air and Gas Institute (CAGI) to provide readers with some insights into the benefits of CAGI’s Verified Performance Program for refrigerated compressed air dryers.
Atlas Copco has a long history serving the Houston-based energy and chemical industries with custom-engineered packages. The objective of this article is to show just a few examples of the custom applications typically engineered and manufactured in the Atlas Copco Houston operation. Opened in 2012, Atlas Copco Houston produces standard compressed air dryers as well as completely engineered air dryers for all markets. The air flow capacity of the dryers, produced at this location, vary from 5 to 12,750 scfm. This capacity range covers heatless, heated purge and blower purge air dryers.
Insufficient focus at the design phase will kill a project. In one aerospace project, insufficient detail was paid to the physical size of the air compressor. The compressor didn’t fit in the allocated space—requiring the extension of the building, and costing tens of thousands of unbudgeted dollars. That had a significant, negative impact on the project return.
