Inspecting Underground Piping

Piping integrity is always a major concern in the chemical process industries (CPI), but the level of concern elevates when piping is buried underground. Soil conditions not only exacerbate general external corrosion, but also increase the difficulty and cost of…

Design Underground Piping For Safety

Buried piping — especially lines carrying hydrocarbons — shoulders many more risks in terms of plant safety and environmental protection than aboveground piping does. Leaks in buried pipes are much harder to detect and, yet, are no less catastrophic. Ironically,…

Compressor offers improved efficiency with smaller footprint

A new rotary gas compressor technology designed by OsComp Systems (Cambridge, Mass.; www.oscomp-systems.com) incorporates advantages of reciprocating piston pumps into a hybrid rotor compressor. With a carefully optimized interior geometry, the new compressor can achieve near-isothermal compression with a large-volume…

Streamlined terephthalic acid process lowers capital and operating costs

A simplified and streamlined new process for producing purified terephthalic acid (PTA), trademarked as Compress PTA and co-developed by The Dow Chemical Co. (Midland, Mich.; www.dow.com) and Davy Process Technology (DPT; London, U.K.; www.davyprotech.com), requires 15% lower capital spending, 20%…

Hansen Solubility Parameters (HSP)

In recent years, a number of factors have further emphasized the importance of solvent selection in the chemical process industries (CPI). These include the increasing regulatory scrutiny leveled on industrial solvents, and an effort by CPI companies to reduce the…

Fermentation Process Development

The range of synthetic biology tools available for manipulating microbial metabolic pathways has expanded significantly in the past decade, opening new routes to chemical products. But the development challenges associated with strain development, as well as scaling up effective fermentation…

A new twist in compressor design reduces energy consumption

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%…

Carbon nanotube ‘paper’ could reduce Pt content in fuel cells

One of the biggest factors hindering widespread adoption of polymer exchange membrane fuel-cells (PEMFCs) is the high price of the platinum metal needed to catalyze the reduction-oxidation chemistry in the fuel cell. In a step toward reducing platinum content, a…
