Drying as a process is one of the most energy-intensive unit operations on the planet. Add to that the fact that dryers are used extensively throughout the chemical process industries (CPI) and it becomes obvious that there ought to be…
As bulk-solids processors look for ways to save money, manufacturers of screening equipment are concentrating on maximizing the efficiency of the equipment they offer. Screening has been prominent in solid-solid separations in the chemical process industries (CPI) for decades. It is…
Faced with increased workloads and time and budget constraints that often restrict external training support, many chemical process operators are forced to get the most out of their heat transfer system with less help. This article offers recommendations for how…

Avoid kinking on tight turns with this tubing Parker Hannifin Tex-Flex fluorinated ethylene propylene (FEP) corrugated tubing (photo) can turn sharp corners without kinking. The manufacturer asserts that the tubing can handle bend diameters four times smaller than a typical…
BinMaster Level Controls Extend level measurement with this flexible probe The Procap capacitance probe (photo) features a flexible, extendable cable design for high-, middle- or low-level detection when the probe must be mounted on top of the bin. The device…
Most chemical engineers involved with operating large chemical process facilities have encountered the following challenge: Several large engineering contractors built the facility in multiple phases, using different computer-software models. Retrieving drawings or data in both digital and non-digital form in…
At a reception Tuesday evening, Chemical Engineering announced this year’s finalists and the winner of the 2009 Kirkpatrick Chemical Engineering Achievement Award, a biennial prize that the magazine has bestowed continuously since the early 1930s. The award recognizes the most…
Security at many U.S. chemical facilities is regulated by the U.S. Department of Homeland Security (DHS; Washington, D.C.; http://www.dhs.gov) under the Chemical Facility Anti-Terrorism Standard (CFATS). Proposed modifications to this regulation are being debated in the U.S. Congress. In fact,…
For wastewater treatment, membrane bioreactors (MBRs) provide superior effluent quality in a small footprint compared to alternative activated-sludge treatment methods. However, MBRs are prone to fouling, and thus may require frequent membrane cleaning with the associated manpower and chemical costs.…
