Researchers from the Dept. of Chemical Engineering, Monash University (Clayton, Victoria, Australia; www.monash.edu), have reported on a new composite polymer hydrogel with light-absorbing particles incorporated within it, that can be used as draw agents in the forward osmosis (FO) process of desalination. The researchers, led by professor Huanting Wang, aimed to develop new...

A technique for protecting structural steel from fire using the endothermic decomposition of magnesium hydroxide has been developed by a team from the Dept. of Chemical Engineering and Materials Engineering, the University of Auckland (New Zealand; www.auckland.ac.nz). Led by professor Mohammad Farid, the team designed a system consisting of an outer layer of gypsum board and an inner mass of Mg(OH)2. The...

Outotec Oyj (Espoo, Finland; www.outotec.com) has introduced a new partial roasting process to purify copper and gold concentrates that are contaminated with arsenic, antimony and carbon. The process is a pretreatment stage for Cu- and Au-extraction plants, and enables the extraction of metals from ores that had previously been unattractive because the impurities create a “huge problem” of...

Earlier this year, the first polylactic acid (PLA) plant based on a new polymerization process was put into service by Synbra Technology in Etten Leur, the Netherlands. The plant — capable of producing up to 5,000 ton/yr of PLA — was built by Sulzer Chemtech Ltd. (Winterthur, Switzerland; www.sulzerchemtech.com), and uses a PLA process jointly developed by Sulzer Chemtech and Purac (Gorinchem...

A carbothermal process for obtaining magnesium — developed by CSIRO (www.csiro.au) Light Metals Flagship (South Clayton, Victoria, Australia) — overcomes previous limitations to commercial viability. For several years, magnesium has been produced mainly by electrolytic routes, from magnesium chloride sources such as seawater and natural brines. More recently, world production has been mainly in...

The first commercial-scale biobutanol plant using the Gevo Integrated Fermentation Technology (GIFT) process is set to come online in mid-2012 at the former site of an ethanol facility in Minnesota. In late January, Gevo (Englewood, Colo.; www.gevo.com) was awarded a U.S. patent for the GIFT separation technology, a key component of the process that allows the separation of C3–C6 alcohols from the...

A new catalyst design, in which gallium atoms are integrated into the zeolite catalyst structure, can increase yields of aromatic compounds from biomass by 40% in a catalytic fast-pyrolysis process. The higher yields of benzene, toluene and xylenes (BTX), as well as ethylene and propylene, achieved with the gallium-containing zeolite...

A proprietary nanoscale catalyst and an updated engineering design have allowed higher conversion rates for transforming the heaviest fractions of crude oil, known as vacuum residue, into high-value transportation fuels, such as diesel. Developed by UOP LLC (Des Plaines, Ill.; www.uop.com) and called Uniflex, the technology combines elements of the CANMET hydrocracking process used by Petro-Canada from...

Solar thermal power The first solar-thermal power plant in Southeast Asia fed its full output of 5 MW into Thailand’s public grid for the first time late January. The facility — designed and built by Solarite GmbH (Duckwitz, Germany; www.solarlite.de) — is also the first commercial solar-thermal plant to produce steam directly from water, thereby eliminating the need for heat-transfer...
