This water-treatment system can aid disposal options for brine
A six-stage water treatment process involving electrocoagulation (EC) and multi-stage flash (MSF) distillation could improve options for the disposal of sludge and brine in applications that include the treatment of water from hydraulic fracturing of oil and gas wells (see…
Growing algae with fluegas CO2
Construction of a 1-hectare (ha) carbon-capture and recycling “synthesizer” demonstration plant has started at Tarong Power Station near the town of Nanango in southeast Queensland, Australia. Tarong Power Station comprises four coal-fired units with a gross generating capacity of 1,400…
April Chementator Briefs
Biobutanol milestones Last month, Cobalt Technologies (Cobalt; Mountain View, Calif.; www.cobalttech.com) announced two achievements toward commercial-scale production of bio-based n -butanol: the demonstration of its biomass pretreatment process, and the demonstration of its advanced-strain fermentation process. In cooperation with…
Expanded certifications for industrial virtualization
Invensys Operations Management (IOM; Plano, Tex.; iom.invensys.com), a division of Invensys, has expanded its certification for virtualization technology, making its industrial automation systems the first to be certified for high availability, disaster recovery and fault tolerance in supervisory control applications…
Plastics with soy-derived protein reduce petroleum use
New biocomposite plastics that combine soybean-meal protein with conventional plastic resins allow significantly lower use of petroleum-based chemicals in polyethylene (PE) and polypropylene (PP) manufacturing. The new class of bioplastics incorporates soybean-meal protein, which is chemically bound to the PE…
A new roasting process slated for commercialization
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…
This MOF selectively captures radioactive iodine
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…
A new PLA process makes its commercial debut
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 —…
