Linde to help commercialize an oil-from-algae process
Sapphire Energy, Inc. (San Diego, Calif.; www.sapphireenergy.com) and The Linde Group (Munich; www.linde.com) have signed an agreement, with a minimum span of five years, to commercialize Sapphire’s process for producing crude oil from algae. The agreement expands an existing partnership…
A solid way to eliminate contaminants from wastewater
CSIRO Minerals Down Under Flagship (Perth, Western Australia; www.csiro.au/MDU) has developed a method that uses hydrotalcite formation to simultaneously remove contaminants from mining and industrial wastewaters in a single step. Current wastewater-treatment processes typically produce lime-based slurries, often with large…
Desalination sans membranes
Researchers from the University of Texas at Austin (www.utexas.edu) and the University of Marburg (Germany; www.uni-marburg.de) are developing a process, called electrochemically mediated seawater desalination, that promises to be an inexpensive way to desalinate small volumes of water. The patent-pending…
Commercialization is set for a biomass-to-gasoline process
A process that is expected to produce high-octane gasoline from non-food biomass for an average cost of $1.50/gal, depending on feed costs, will be commercialized by Cool Planet Energy Systems (Denver, Colo.; www.coolplanet.com). The company has tested the process in…
A gas turbine with low NOx emissions
NEDO and Hitachi Ltd. (Tokyo, www.hitachi.com) have developed a new combustion technology that could reduce the emissions of oxides of nitrogen (NOx) to below 10 ppm without the addition of diluents. As part of the CCS-IGCC project (carbon capture and…
July Chementator Briefs
ODC for Cl2 production Last month, ThyssenKrupp Uhde GmbH (Dortmund; www.uhde.eu) and Bayer MaterialScience AG (BMS; Leverkusen, both Germany; www.bayermaterialscience.com) commercially launched — worldwide — the oxygen depolarized cathode (ODC) technology, which BMS and ThyssenKrupp Uhde/UhdeNora developed to improve…
Bio-butanol scaleup moves ahead with trials
In April development tests, Cobalt Technologies (Cobalt; Mountain View, Calif; www.cobalttech.com) produced n -butanol at the fermentation scale of 100 m3 per run, demonstrating lower production cost than butanol produced from petroleum. This represents production that is a factor of…
Burner technology enables reduced NOx with short flame length
To comply with increasingly stringent regulations for NOx emissions, operators of industrial plants often turn to low-NOx burners to avoid much more costly post-combustion treatment approaches like selective catalytic reduction (SCR). But low-NOx burners are plagued by significant losses in…
These scavengers of water pollutants have a magnetic attraction
A process that uses magnetic nanoparticles, coated with a reactive material, to clean up contaminated water for human use is being developed at Stanford University (Stanford, Calif.; www.stanford.edu). The nanoscavengers, as they are called, are distributed in the water to…
Improved corrosion control in refinery steam systems
GE Power & Water (Trevose, Pa.; www.ge.com) has introduced a novel, dual-pronged approach to corrosion inhibition for boiler and steam-condensate systems in petroleum refineries. The technology is designed to prevent attack by acidic species on steam-system surfaces, providing reliability to…
