Printed electronics made possible by this carbon-nanotube-production process
A recently commercialized method for growing single-walled carbon nanotubes (SWCNs) in large quantities enables their use in a downstream process for depositing semiconducting inks onto flexible surfaces. Southwest NanoTechnologies Inc. (Norman, Okla.; www.swentnano.com) has developed a scalable technique (CoMoCAT process)…
Recovering energy from fluegas
Alcoa of Australia (www.alcoa.com.au) has developed a process to recover sensible and latent heat from the fluegas (FG) produced by Bayer alumina calciners, and use the heat to evaporate Bayer spent liquor. Peter Hay, of Alcoa’s Technology Delivery Group, at…
Large-diameter reverse osmosis product lowers cost and reduces footprint
Koch Membrane Systems Inc. (KMS; Wilmington, Mass.; www.kochmembrane.com) recently unveiled large-diameter reverse osmosis (RO) elements and pressure vessels for seawater desalination that offer cost savings and reduced footprints. The new RO element and pressure vessel combinations have an 18-in. dia.…
‘Super Boiler’ achieves higher efficiency through the recovery of waste heat
An advanced heat recovery system (AHRS) that boosts the fuel-to-steam efficiency of firetube boilers by as much as 15% will be produced by Cannon Boiler Works Inc. (New Kensington, Pa.; www.cannonboilerworks.com) through a license agreement with the Gas Technology Institute…
A new electrochemical process for making K2FeO4
A new process for producing the oxidizing agent potassium ferrate (VI) (K2FeO4) can routinely generate multi-kilogram quantities per day, say scientists. Ferratec (St. Louis, Mo.; www.theincubationfactory.com) and partner Electrosynthesis (Lancaster, N.Y.; www.electrosynthesis.com) have licensed the process technology from Battelle (Columbus,…
Sound water treatment delivers environmental and economic benefits
A two-year collaboration between Ashland Hercules Water Technologies (AHWT; Wilmington, Del.), a commercial unit of Ashland Inc. (Covington, Ky.; www.ashland.com), and BASF Nederland B.V. (Nijehaske, the Netherlands) has demonstrated that a combination of ultrasonic microbial control and corrosion inhibitors not…
