An alternative to chlor-alkali
Earlier this year, NSR Technologies (Decatur, Ill.; www.nsr-tech.com) commercialized its patented process for producing potassium hydroxide (45–50 wt.%) and dilute hydrochloric acid via a membrane separations technology. The company’s flagship production facility in Decatur, Ill. is the first commercial application…
A replacement for Cr+6
Aculon, Inc. (San Diego, Calif.; www.aculon.com) has developed a formulation of its proprietary SAMP technology (Self-Assembled Monolayer of Phosphate) that can be used as an alternative to hexavalent chromium used in primers and conversion coatings to increase the adhesion of…
Chementator briefs for August
Bioplastics DSM Engineering Plastics (Sittard, Netherlands; www.dsm.com) has introduced EcoPaXX, a biobased, high-performance engineering plastic that is said to have a zero carbon footprint (100% carbon neutral from cradle to grave). Approximately 70% of EcoPaXX is made from building blocks…
A silver-based antimicrobial
Pure Bioscience (El Cajon, Calif.; www.purebio.com) has developed silver dihydrogen citrate (SDC), the first antimicrobial approved by the U.S. Environmental Protection Agency (EPA; Washington, D.C.) in 30 years, with applications in the pharmaceutical, personal care, household, food and textile markets.…
A gypsum-free, energy-saving route to lactic acid
Uhde GmbH (Dortmund, Germany; www.uhde.biz) is developing a new process for producing lactic acid (LA) — a monomer for making the biodegradable plastic polylactic acid (PLA) — that does not require a distillation step. As a result, savings in steam…
Making solar panels even greener
Last month, Malibu GmbH & Co, KG (Bielefeld, Germany; www.malibu-solar.de) started up a thin-film photovoltaic-module fabrication facility that is claimed to be the world’s first to eliminate the use of nitrogen trifluoride (NF3) — a greenhouse gas with a significant…
The missing piece for wireless process control
Last month, Honeywell Process Solutions (HPS; Phoenix, Ariz.; www.honeywell.com/ps) unveiled the process industry’s first redundant wireless system gateway (WSG), connecting the last major gap in the path to wireless process control. WSGs manage data between wireless field instrumentation and a…
New catalyst boosts liquid-fuel yield from heavy hydrocarbons
A new zeolite catalyst that increases yields of light cycle oil (LCO) from high molecular weight “bottoms” hydrocarbons in petroleum fluid catalytic cracking (FCC) units was commercialized last month by Grace-Davison, an operating segment of W.R. Grace & Co. (Columbia,…
Direct conversion of cellulose to HMF demonstrated
Researchers at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pln.gov) have published the first direct route for converting plant cellulose to 5-hydroxymethylfurfural (HMF), a valuable platform chemical for the production of both plastics and biofuels. Appearing in the June issue…
A new support for biofilters
Researchers from the Environmental Biotechnology Cooperative Research Center (Sydney and Perth, Australia; www.ebcrc.com.au) have developed a new way to harness bacteria to biodegrade odor-causing substances. Traditional biofilters typically employ compost supported on wood chips to trap the odor-producing substances, and…
