Dimensionless numbers refer to physical parameters that have no units of measurement. These numbers often appear in calculations used by process engineers. As long as consistent units are used, dimensionless numbers remain the same whether metric or other units are…

Researchers from the University of California at Los Angeles (UCLA; www.ucla.edu) Henry Samueli School of Engineering and Applied Science have created what is claimed to be the first surface texture that can repel all liquids, no matter what material the…
A modular, skid-mounted hydrogen-production plant developed by Linde AG (Munich, Germany; www.linde.com) uses a modified version of conventional steam-methane reforming (SMR) to generate hydrogen from inexpensive natural gas, rather than relying on more costly methods of hydrogen production, such as…
For the first time, polypropylene carbonate (PPC) polyol, a versatile polymer made from CO2, is available at a commercial scale. Produced by Novomer Inc.’s (Waltham, Mass.; www.novomer.com) polymerization process, PPC polyol has been adopted into a formulation for polyurethane hot-melt…
A cement plant in Taiwan has been retrofitted with the largest CO2-capture plant to use calcium-looping technology to date. The project, run by Taiwan’s Industrial Technology Research Institute (ITRI; Hsinchu, Taiwan; www.itri.org), demonstrates ITRI’s high-efficiency calcium-looping technology (Heclot) at a…
Meanwhile, a new class of highly fluorinated polymers is being developed at the Institute of Microstructure Technology (IMT), Karlsruhe Institute of Technology (KIT; Karlsruhe, Germany; www.kit.edu) that repels both water and oil. Last month, IMT was awarded €2.85 million funding…
Greene’s Energy Group LLC (Houston), a provider of testing services, equipment rentals and specialty services for the oil-and-gas industry, names Robert Fraser regional business-development manager, based in Dubai. Philippe Sauquet becomes president of refining and chemicals, and a member of…
If the word “modular” brings to mind a trailer office parked on site, it’s time to revisit modular systems. Today’s modular system go well beyond office space and tool sheds, and can contain almost anything from a skid-mounted filtration system…
Enzymes, nature’s catalysts, have been used in industrial processes for centuries. Now, they are coming into their own in the chemical process industries (CPI). As green chemistry becomes an industry mantra, pressures to reduce product cost, facility carbon footprint and…
