Municipal water sludge-optimization technology poised for growth
A sludge-optimization technology for municipal water-treatment facilities is poised for rapid growth after the exclusive worldwide patent-licensing rights for the technology were acquired by CNP Technology Water and Biosolids Corp. (Kenosha, Wisc.; www.cnp-tec.com). The technology, known as AirPrex, was initially…
Mercury removal with modified aluminosilicate clay
The first commercial contract delivery was recently made for an emissions control product that removes mercury from fluegas without the use of activated carbon. The product, known as AS-HgX, is made by Novinda Corp. (Denver, Colo.; www.novinda.com), and will be…
Monitoring pipeline deposits in realtime
The presence of scale depositions in pipelines can restrict flow, limit heat transfer and decrease efficiency. The ability to monitor pipelines for depositions helps avoid issues and optimize costs. The Deposition Watch system from Flowrox Inc. (Linthicum, Md; www.flowrox.us) presents…
Modern Water-Treatment Challenges
Water and wastewater treatment are extremely important at liquefied natural gas (LNG) facilities and other industries that are blossoming due to the shale-gas boom. Engineering concerns are similar to those of other industrial water-treatment and power-generation systems, but with the…
This process realizes large costs savings for manufacturing silicon wafers
Crystal Solar Inc. (Santa Clara, Calif.; www.xstalsolar.com) is preparing for high-volume production of silicon wafers using a process that forms the wafers directly from trichlorosilane (TCS) gas using a chemical vapor deposition (CVD) epitaxy process that can significantly lower the…
Demonstration plants for biomass-to-sugar technology under construction
Edeniq Inc. (Visalia, Calif.; www.edeniq.com) announced progress in building demonstration facilities in Brazil and China that feature the company’s proprietary process for converting cellulosic biomass into industrial sugar for fermentation or catalytic conversion (diagram). In Brazil’s São Paulo state, Edeniq…
September Chementator Briefs
CO2-to-syngas . . . Scientists from the University of Illinois at Chicago ( www.uic.edu) have developed a catalytic system — molybdenum disulfide and an ionic liquid — to convert CO2 into synthesis gas, (syngas; a mixture of CO and…
Microporous vanadosilicate efficiently removes cesium from wastewater
The effective removal of Cs+ ions from contaminated groundwater, seawater, and radioactive nuclear waste is crucial for public health and for the operation of nuclear power plants. Although several methods for the removal of Cs+ ions have been developed, there…
This production process cuts Pt usage in catalytic converters in half
Chemists from the National Institute of Advanced Industrial Science and technology (AIST; Tsukuba City, Japan; www.aist.go.jp) have developed a procedure for making the catalysts used in catalytic converters for treating the exhaust from diesel engines. The process, developed with support…
Demonstration of methane fermentation to lactic acid
What is said to be the world’s first fermentation pathway from methane to lactic acid has been demonstrated by Calysta, Inc. (Menlo Park, Calif.; www.calysta.com). The fermentation process begins with an organism that feeds off of methane rather than typical…
