The release of silver from industrial wastewater has caused serious environmental problems. Many methods have been developed to remove silver ions from industrial wastewater, including chemical precipitation, ion exchange, electrolysis, replacement, membrane and reverse osmosis. Several adsorbents have been used…
A new commercial manufacturing process for carbon nanotubes (CNTs) produces tubes in the range of 1–10 mm in length (5–12-nm dia.), two orders of magnitude longer than currently available CNTs, which typically have lengths from 5–20µm. “Despite attractive mechanical and…
Gas Innovations (La Porte, Tex.; www.gasinnovations.com) has signed a 15-year, pay-per-use agreement with Haldor Topsøe A/S (Topsøe; Lyngby, Denmark; www.topsoe.com) for a second on-site carbon-monoxide production unit, using Topsøe’s electrolytic Carbon Monoxide solution (eCOs) technology. The first eCOs unit in…
Bio foam control Last month, Novozymes A/S (Bagsvaerd, Denmark; www.novozymes.com) introduced Fermax, an enzyme protease that prevents foam development during the sugarcane ethanol fermentation process, while delivering improved control and replacing chemicals. For an average size plant, trialing partners experienced…
Scandium International Mining Corp. (Sparks, Nev.; www.scandiummining.com) is about to become the first company to achieve production from a primary scandium mine, with its project near the small town of Nyngan, New South Wales, Australia. The production of scandium from…
Demand for carbon fiber (CF), which can be used to make strong, lightweight composite materials for improving vehicle fuel economy and wind-power generation, has been growing. However, widespread use of these advanced composites has been limited by the high production…
Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) has developed a hydrothermal liquification (HTL) process that converts sewage sludge directly into “biocrude oil,” which can then be refined by conventional methods into liquid fuels, such as gasoline, diesel and jet…
The glass industry’s needs are extremely diverse, and manufacturers demand stability and precision in their furnace operations. Air Products (Lehigh Valley, Pa.; www.airproducts.com/glass) has released an advanced burner, the patent-pending Cleanfire HR e, which is said to be the first…
Last month, the first compact plant to produce synthetic fuels from solar energy and CO2 extracted from air was commissioned in Finland, as part of the Soletair project, which is coordinated by the Technical Research Center of Finland (VTT: Espoo;…
The Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu) is cooperating with research institutions and industry partners to develop a novel process chain for the synthesis of methanol, either without the use of fossil resources or by reusing CO2 from undesired…
