A process that uses magnetic nanoparticles, coated with a reactive material, to clean up contaminated water for human use is being developed at Stanford University (Stanford, Calif.; www.stanford.edu). The nanoscavengers, as they are called, are distributed in the water to…
Ammonia is a promising candidate for scrubbing carbon dioxide from fluegas, since each ammonia molecule can absorb one molecule of CO2, whereas amine absorbers require two molecules to do the same job. However, because ammonia is volatile, the fluegas must…
SJV Hose Jet Filters remove dust from air flowrates from 10,000–500,000 m3/h and are suitable for use in the non-metallic industry, wood and plastic processing, blast-furnace operations, and other sectors of the chemical processing industries. These filter systems can also…
Security of SCADA (supervisory control and data acquisition) and other industrial control systems (ICSs) is a complex subject, and one that has received much attention in recent years. While modern industrial control systems use many of the same computers, operating…
Selecting air-pollution control equipment can be tricky. It’s not only difficult to determine which pollutants must be controlled, but also which type of equipment will best control them to required levels for any given process or facility because there is…
This flowrate totalizer has an explosion-proof enclosure Precision Digital The PD6830 ProtEX-RTP Pulse Input Rate/Totalizer has a rugged, explosion-proof, NEMA 4X enclosure and is designed for the quick and easy display of local or remote flow information in hazardous areas.…
Ongoing advances in the design and use of dry gas seals (DGSs; [ 1]) — as an alternative to traditional oil-lubricated wet seals [ 2] — have helped to improve the reliability and efficiency of compressors throughout the chemical process…
During process operations, elevated pressure inside of isolated zones within a process or system can be rapidly reduced by the release of gas and vapor to a dedicated blowdown network. Analysis can be carried out to determine whether a given…
Evonik Industries AG (Essen; www.evonik.com) and OPX Biotechnologies, Inc. (OPXBio; Boulder, Colo.; www.opxbio.com) have entered into an agreement to jointly develop certain bio-based specialty chemicals. The joint development agreement was signed May 3, 2013, and calls for OPXBio to use its…
Regardless of whether one is producing acrylic acid, butanediol, tetrahydrofuran or other chemicals, residues will arise that need to be disposed of. This company delivers turnkey thermal utilization plants for these and other production facilities that ensure not only the…
