New process for monoethylene glycol completes pilot stage
A new process for producing monoethylene glycol (MEG) from synthesis-gas-based feedstocks is nearing completion of extensive pilot plant operation, according to developers Eastman Chemical Co. (Kingsport, Tenn.; www.eastman.com) and Johnson Matthey Davy Technologies Ltd. (London, U.K.; www.davyprotech.com). The technology enables…
Improving extraction yields of Ni and Co from laterite
Low-grade nickel (less than 1.5 wt.%) laterite ores represent about 70% of global reserves but account for only 40% of nickel production. Increasing demand for nickel in recent years has created the need to process such ores. Atmospheric acid leaching…
First commercial process for K2SO4 from polyhalite completes pilot
Pilot plant operation has been completed for a process that produces the fertilizer potassium sulfate from the mineral polyhalite, a hydrated sulfate of potassium, magnesium and calcium. The process, developed by Intercontinental Potash Corp. (ICP; Golden, Colo.; www.icpotash.com), resurrects a…
An efficient way to make fermentable sugars from fibrous waste
The National Food Research Institute (NFRI) of the National Agriculture and Food Research Organization (NARO; Tsukuba City, Japan; www.naro.affrc.go.jp) has developed an enzymatic pretreatment process for producing highly concentrated sugar solution from fibrous materials containing rice straw and starch. The…
Metabolic engineering makes plants produce more oils
A research team from the University of Western Australia (Perth; www.uwa.edu.au), led by professor Dongke Zhang, has pioneered the application of higher plants for new-generation biofuel production. Metabolic engineering of Arabidopsis thaliana — a small flowering plant native to Europe…
Corrosion: the silent killer
CUI — that acronym should be enough to capture your attention. All chemical process industries (CPI) plants are aging — and some are aged, especially in the U.S. and Europe. Corrosion under insulation (CUI) should be regarded as a silent…
Dandelion rubber
Last month saw the start of a five-year joint research project to extract rubber from dandelion plants to make tires. In collaboration with Continental AG (Hannover, Germany; www.continental-tires.com), the Fraunhofer Institute for Molecular Biology and Applied Ecology (IME; Aachen, Germany;…
Transporting more H2 gas
The Linde Group (Munich, Germany; www.linde.com) has developed a new storage technology that will enable a much more efficient transport of larger amounts of hydrogen. The new solution works at a higher pressure of 500 bars (7,250 psi) and uses…
Plasma-modified CNTs show promise for water purification
An international team of researchers claims to have developed carbon nanotube (CNT) membranes with an ultrahigh specific-adsorption capacity for salt that is two orders of magnitude higher than that found in current activated-carbon-based water-treatment systems. The team includes researchers from…
KIT makes ‘gasoline’ for the first time
Last month, the synthesis stage of the bioliq (biomass to liquid Karlsruhe) pilot plant produced gasoline for the first time at the Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu). The achievement is a milestone in that all stages of the…
