The new two-stage DuoLine rotary-vane vacuum pumps feature a newly developed pump system with optimized cooling. These changes have a significant impact on the pump’s service life, says the manufacturer. The long maintenance intervals, the energy-efficient motors and the optional…
A new range of compact, lightweight motorized valves has been introduced for applications where electric actuation is required. The valves are quiet in use, and can be operated by a 24-V d.c. power supply, or by voltages between 24–48 and…
The ViscoFlux mobile drum-emptying system has been further developed and now has an optional control unit enabling integration into a range of filling processes. For example, an end position cutoff can be integrated into the ViscoFlex so that the pumping…
Polymer-based piping systems offer a number of advantages, along with some limitations, compared to metallic and other non-polymeric pipe materials. The use of thermoplastic piping in the chemical process industries (CPI) must be carefully considered on a case-by-case basis because…
This company’s E-Series Plastic AODD (air-operated double-diaphragm) pumps have been upgraded with electrically conductive polytetrafluoroethylene (PTFE) diaphragms (photo) to provide safer transfer of chemicals while avoiding electrostatic discharge. As a result, E-Series pumps equipped with conductive PTFE diaphragms can be…
Launched in May, the new semi-hermetic, six-cylinder GEA Block piston compressor HG46 CO2 T has a displacement of 21.8 to 30.3 m3/h. It is said to be the biggest semi-hermetic compressor for transcritical CO2 applications with operating pressures of up…
The new Food Grade range of pipework systems is said to be the first product range on the market that meets the stringent requirements of the European standard EC 1935/2004, as well as the U.S. Food and Drug Admin. (FDA)…
In April development tests, Cobalt Technologies (Cobalt; Mountain View, Calif; www.cobalttech.com) produced n -butanol at the fermentation scale of 100 m3 per run, demonstrating lower production cost than butanol produced from petroleum. This represents production that is a factor of…
GE Power & Water (Trevose, Pa.; www.ge.com) has introduced a novel, dual-pronged approach to corrosion inhibition for boiler and steam-condensate systems in petroleum refineries. The technology is designed to prevent attack by acidic species on steam-system surfaces, providing reliability to…
On the heels of its successful scaleup of bio-butanol, Cobalt is looking for pathways to use that molecule as a building block for other products. The company has announced plans to build the first bio-butadiene plant in Asia. Projected to…
