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…
Evonik Industries AG (Essen, Germany; www.evonik.com) has awarded WorleyParsons Ltd. (North Sydney, Australia; www.worleyparsons.com) a contract for the detailed engineering, procurement support and construction management on the building of world-scale plants for the production of isophorone and isophorone diamine. 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…
Air Products (Lehigh Valley, Pa.; www.airproducts.com) has entered into a definitive agreement to acquire all of DuPont’s (Wilmington, Del.; www.dupont.com) interest in DuPont Air Products NanoMaterials LLC (DA NanoMaterials; Tempe, Ariz.; www.nanoslurry.com ), the two companies’ 50-50 joint venture serving…
A challenge in recovering fissile material from spent nuclear fuel is separating radioactive components that cannot be reused as fuel. Researchers at Sandia National Laboratory (Albuquerque, N.M.; www.sandia.gov) have fabricated metal-organic frameworks (MOFs) capable of selectively capturing gaseous iodine from…
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 —…
