Isothermal compression gets practical
Mechanical engineering students have been taught that true isothermal compression, while ideal from an energy-efficiency perspective, is not achievable. However, a late 1800s technology, the Taylor Compressor has delivered isothermal compression in large industrial applications for nearly a century. The…
Synthesizing adipic acid without generating N2O
Adipic acid, a precursor for the synthesis of nylon, is usually produced through nitric acid oxidation of cyclohexane, a process which has disadvantages, such as the emission of nitrous oxide — a greenhouse and ozone-depleting gas — as well as…
LED sight-glass light
Illumination is required for visual inspection of a process through a sight glass in a vessel or tank. A newly demonstrated light source, developed by L.J. Star Inc. (Twinsburg, Ohio; www.ljstar.com) and marketed as the LumiStar3000, is said to be…
Phase-change slurry
Researchers from the Fraunhofer Institute for Environmental, Safety and Energy Technology (Umsicht; Sulzbach-Rosenberg; www.umsicht.fraunhofer.de) and RWTH Aachen University (both Germany; www.rwth-aachen.de) have developed a new phase-change material (PCM) trade-named CryoSolPlus. The PCM is a dispersion of solid paraffin beads and…
Onsite CN generation
Gold mines using traditional cyanide-leaching extraction processes will benefit with the launch of a new technology allowing onsite production of sodium cyanide. The technology, developed by Synergen Met Pty Ltd (Brisbane, Australia; www.synergenmet.com), will eliminate a range of hazardous activities…
‘High-entropy’ alloy
Researchers from North Carolina State University (Raleigh; www.ncsu.edu) and Qatar University (Doha; www.qu.edu.qa) have developed a new metal alloy that is claimed to have a higher strength-to-weight ratio than any other existing metal material. The low-density, nanocrystalline alloy — Al20Li20Mg10Sc20Ti30…
New enzyme
Last month, Novozymes (Copenhagen, Denmark; www.novozymes.com) launched a new enzyme, dubbed Eversa, which is said to be the first commercially available enzymatic solution to make biodiesel fuels from waste oils. The enzymatic process converts used cooking oil or other lower-grade…
Direct fermentation to produce propylene
Global Bioenergies (Evry, France; www.global-bioenergies.com) says that last month it developed a proprietary strain of microorganism that directly produces propylene by the fermentation of glucose. The company claims this is the first time propylene has been produced entirely by a…
Biodegradable drilling lubricant garners positive field results
An encapsulated, biodegradable drilling-fluid additive designed to reduce friction on drill bits and piping inside oil wells has been demonstrated successfully in more than 30 wells across North America following its launch in mid-2014. The lubricant product, known as Encapso,…
A one-step, phosgene-free route to urethane
Researchers at the National Institute of Advanced Industrial Science and Technologys (AIST) Interdisciplinary Research Center for Catalytic Chemistry (Tsukuba, Japan; www.aist.go.jp) have developed a new reaction process to synthesize aromatic urethane — a promising starting material for the production of…
