The ADPC 302 (photo) is a unique, in-process contamination management system for particle contamination monitoring in the semiconductor industry. The system measures the number of particles in wafer-transport carriers, and its fully automated, patented process localizes and counts particles from…
The new motorized actuation of the 2030 series valve actuator (photo) is composed of an electric stepping motor (400 steps per revolution), a flexible coupling, a gear box and stroke detector. Every part of the gear box is made of…
The A Series eccentric-disc pump (photo) incorporates a variety of upgrades, including the implementation of ISO PN 16/ANSI 150 flanges. The A Series has also doubled its maximum differential pressure from 5 bars (72 psi) to 10 bars (145 psi),…
The scaleup of liquid mixing systems does not have to be a mystery. The principles are quite well understood, although knowing which principles apply is not always obvious. Follow this guidance to improve operation. 1. Liquid mixing scaleup. Liquid mixing…
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…
