Combustible Dust Standard Gets a Facelift
While NFPA 652 creates a general set of requirements for mitigating explosion hazards, equipment providers improve offerings to assist with compliance The National Fire Protection Association (NFPA; Washington, D.C.; www.nfpa.prg) recently released the first edition of NFPA 652 Standard on…
Continuously cleaned filters for challenging water streams
A new self-cleaning filter from Spiral Water Technologies Inc. (San Rafael, Calif.; www.spiralwater.com) can efficiently treat water with 25,000 mg/L total suspended solids (TSS). According to Spiral Water CEO Ashwin Gulati, the filters use much less energy — reportedly just…
Thermochemical regenerator system demonstrated in glass facility
A patented thermochemical regenerator system developed by Praxair, Inc. (Danbury, Conn.; www.praxair.com) has been demonstrated at its first industrial site, a glass-making facility in Mexico. The system, known as the Optimelt heat-recovery system, lowers fuel consumption in oxy-fuel furnaces, which…
A new catalyst removes cyanide from wastewater
Chemists at the University of Amsterdam (UvA; the Netherlands; www.uva.nl) have discovered a new catalytic method for removing cyanide ions from industrial wastewater. The heterogeneous catalyst — discovered jointly by Paula Oulego Blanco, Raveendran Shiju and professor Gadi Rothenberg from…
This ‘ultrabattery’ makes its commercial debut
Ecoult Energy Storage Solutions (Sydney, Australia; www.ecoult.com) is entering the commercial and residential energy-storage markets with an “ultrabattery,” which was developed by CSIRO (www.csiro.au), with contributions from Furukawa Battery Co. (Yokohama, Japan; www.furukawadenchi.co.jp) and funding from the Australian and Japanese…
High-efficiency cell removal
Acoustic wave separation (AWS) technology can improve cell-culture clarification in biopharmaceutical applications by enabling high-efficiency, continuous removal of cells in a closed system without centrifugation. Developed by FloDesign Sonics (Wilbraham, Mass.; www.flodesign.org) and licensed to Pall Corp. (Port Washington, N.Y.;…
Making a mercury-removing polymer from industrial waste
Scientists at Flinders University (Adelaide, Australia; www.flinders.edu.au) have synthesized a new polymer that is extremely effective at binding to mercury for removal from water and soil. The new material — called sulfur-limonene polysulfide — is created from a reaction (diagram)…
Chementator Briefs
Nylon Recycling Validation has been completed, and construction is underway for an industrial-scale facility that will recycle technical textile waste when it starts up in 2016 at a site in Gorzów, Poland. The facility is part of Solvay S.A.’s (Brussels,…
CPI Salaries Hold Steady; Workforce Solutions Expand
Conditions in the U.S. CPI continue to support high salaries for engineers and skilled technical workers, but conditions also continue to sustain ongoing workforce challenges Engineering expertise and technical know-how continue to be in high demand in the chemical process…
‘Switchable solvent’ technology is a promising development for advancing forward osmosis
Forward osmosis (FO), whereby a concentrated salt solution is used to “draw” water through a membrane from a less-concentrated salt solution (via osmotic pressure), has the advantage over reverse osmosis (RO) in that high pressures, with the associated pumps and…
