Mechanical processes can offer an environmentally friendly and safer option to chemical water treatment Non-chemical methods for conditioning water for use in cooling towers and boilers have been investigated, marketed and installed for over 100 years. In light of the…
The use of appropriate hazardous-area lighting in the chemical process industries (CPI) is a key factor when it comes to improving overall plant safety and worker productivity, and supporting the best maintenance practices. The potentially hazardous conditions associated with many…
Mechanical seals play a pivotal role in the chemical process industries (CPI). As the sealing interface between rotating process equipment and the materials contained inside, these devices prevent product leakage and fugitive emissions, while permitting process machines, pumps and compressors…
As heat exchangers age, their tube thickness decreases because of erosion, corrosion or a combination of both. Installing thin sleeves in tubes in which the tube walls have become so thin that failure is imminent is a maintenance technique useful…

The stirred tank reactor with rotating mixers remains the backbone of the chemical process industries (CPI). While mixing is considered a mature technology, it is clear that continued technological development is necessary to achieve the state-of-the-art design demanded by ever-increasing…
This survey of modern particle-measurement technologies demonstrates how selection criteria vary by application Particulate systems are everywhere; they are responsible for bright red sunsets, the texture of chocolate and the rate of drug delivery in the human body. Particulate processing…
A hard biomaterial Researchers at the Fraunhofer Institute for Manufacturing Engineering and Applied Materials Research (IFAM; Bremen, Germany; www.ifam.fraunhofer.de) have developed a granulate form of a biomaterial that may replace titanium used as screws and other hardware in medical applications.…
ASA Analytics Plugging is not an issue with this phosphorus analyzer The ChemScan mini oP analyzer (photo) for ortho-phosphorus analysis features flow paths designed to avoid plugging. The analyzer uses large orifice sizes, compared to capillary tubes and needle valves…
