While air-sensitive materials may not be a part of every chemical process, certain catalysts, OLED (organic light-emitting diode) applications, inert gas welding, lithium-ion battery applications and other chemical processes do, indeed, require the inclusion of air-sensitive materials. And, when such…
In an integrally geared centrifugal compressor (Figure 1), several impellers are mounted on the ends of high-speed pinion shafts, which are rotated by a bull-gear. Each impeller’s casing is mounted directly on the horizontally split gear casing. As is the…
This company has been awarded a contract to develop special vacuum pumps for the ITER fusion reactor (photo) — a multinational project to further fusion power plants. In order to carry out the plasma reaction, it is necessary to evacuate…
The portfolio of Neles ceramic E-Series control valves (photo), recognized for being extremely erosion resistant, has now been expanded to NPS 8 in. (DN 200) in pressure Class 300 (PN40). The E-series valve is the most erosion-resistant control valve available.…
APSPG tubing is specially formulated to withstand the repeated compression and release actions of peristaltic pumps and offers consistent performance in pharmaceutical, biopharmaceutical and laboratory uses. Made of platinum-cured, low-volatile-grade silicone material, the finished tubing carries the United States Pharmacopoeia…
This company now offers its new SQEx.2 part-turn actuator — the explosion-proof version of its SQ actuator, which was introduced at the beginning of 2013. In line with qualification requirements for hazardous environments, the SQEx.2 meets the European ATEX and…
This multi-port valve block from the iComLine Series is made of ultra-pure PVDF and features innovative seat-diaphragm technology with PTFE. This combination allows very heavy-duty switching cycles and temperature resistance up to 150°C — features that are not possible with…
These vacuum inlet traps protect pumps across many applications, from laboratory settings to scalable production systems. The inlet vacuum traps feature user-selectable filter elements for removing the corrosive gases and abrasive particles created by processes that use volatile organic compounds…
How big can a fermenter get? And what would the biggest fermenter look like? The answers to these questions depend upon how the requirements of heat transfer, mass transfer (gas-to-liquid), and momentum transfer (mixing) are met. In an earlier article…
Construction is underway in France on a pilot plant for what is believed to be the first fermentation process capable of directly producing the light olefin isobutene. Global Bioenergies (Evry, France; www.global-bioenergies.com) expects to begin operations of a 500-L fermentation…
