This article provides practical guidance for engineers and highlights the importance of combining mathematical skills, domain expertise and proper communications The role of mathematical models in chemical engineering keeps increasing, to the point that some engineers become specialized “modelers.” To…
Every two years, Chemical Engineering honors an innovative technology that has been commercialized with the Kirkpatrick Chemical Engineering Achievement Award. This year, we have six finalists who will have the opportunity to present their technologies at the Chem Show in…
Plant Watch Perstorp will construct new plant for sodium formate deicer product May 9, 2019 — Perstorp AB (Perstorp, Sweden; www.perstorp.com) plans to construct a new plant in Perstorp, Sweden. The plant will increase capacity for Pergrip Run NF, the…
Hydrogen gas is used widely in industry, including in metal annealing, float-glass production and silicon wafer manufacturing, among others, but greater than 80% of the H2 used for these processes is typically vented or flared as waste. A new electrochemical…
The transition-metal-catalyzed reduction of nitrogen is an alternative to the traditional energy-intensive Haber-Bosch process for producing ammonia. In these reaction systems, metallocenes or potassium graphite are typically used as the reducing reagent, and conjugate acids of pyridines or related compounds…
The first high-strength, wrought-aluminum alloy powder designed for use in additive manufacturing (3-D printing) applications is moving into commercial production. The powder was developed by HRL Laboratories (Malibu, Calif.; www.hrl.com) for use in laser powder-bed fusion 3-D printers. The company…
Scientists at the Chinese Academy of Sciences (Beijing; www.cas.cn) and Yangzhou University (Jiangsu, China; www.yzu.edu.cn) have developed a technique for disinfecting water by using graphitic carbon nitride sheets. They claim their technique purifies water in 30 minutes, killing more than…
Eastman Chemical Co. (Kingsport, Tenn.; www.eastman.com) is ready to commercialize a new chemical-recycling technology that can handle a wide variety of mixed plastic waste, including plastic materials that cannot be handled by conventional recycling processes. “We are modifying the front…
Paying closer attention to the air-filtration systems of pneumatic conveying operations can avoid losses in efficiency in compressed-air usage during filter cleaning The inefficient use of compressed air in solids-handling processes, such as pneumatic conveying, can waste a significant amount…
Apart from ensuring the conformity of the process and the quality of the product, professional calibration, first and foremost, improves the quality of the process At many plants in the chemical process industries (CPI), measurement instrumentation is usually calibrated during…
