In most process control applications, larger valves tend to be fitted with pneumatic actuators that provide significant positioning forces. In these situations, the positioner is used to precisely position the valve by filling the actuator with the corresponding amount of…
The new EcoPrime metering pump delivers a precise flowrate in low-pressure liquid chromatography (LPLC) systems, and provides a linear gradient between 0.5 and 99.5% — with 0.5% accuracy. Traditional systems only work linearly over a range between 20 and 70%,…
The 8681 control head was developed for decentral automation of hygienic seat valves, butterfly valves and ball valves. It supplements the company’s Element Series of control heads, digital positioners and process controllers for diaphragm, angle seat and globe valves. The…
The new three-way Water Manifold enables researchers to connect three water-cooled condensers to a single water supply. With the main body constructed of anodized aluminum, the manifold is designed to be clamped to fume hood scaffolding in either vertical or…
Impending standards requiring that cellulosic ethanol be used in gasoline blending have focused attention on building a capacity for bioethanol from non-food sources. In a development that may begin to meet that need, a plant employing a unique method for…
China produces about 98% of the world’s electrolytic manganese metal (EMM), a vital ingredient used in specialty steels, aluminum and electronics. In contrast, the U.S. produces no EMM, says Nick Weir, an executive with U.S. American Manganese Inc. (AMY; White…
H.C. Starck GmbH (Goslar, Germany; www.hcstarck.com) and Clausthaler Umwelttechnik-Institut GmbH (Cutec; Clausthal-Zellerfeld, Germany; www.cutec.de) have joined forces to successfully develop a completely new generation of catalysts and process technology for the production of substitute natural gas (SNG) from biomass as a…
Large-volume polypropylene and polyethylene storage tanks from this company are available in capacities from 100 to 50,000 gal. The ready-for-installation tanks are made by extruding polypropylene or polyethylene around a steel drum mold. They are manufactured in various thicknesses, according…
Mitsubishi Chemical Corp. (MCC; Tokyo, www.m-kagaku.co.jp, MCC) is developing bio-based technology for producing propylene, butadiene, 1,4-butanediol (BDO), terephthalic acid and succinic acid from glucose. In collaboration with North American partners, MCC plans to start production of succinic acid and 1,4…
The chemical process industries (CPI), like many others, increasingly employ non-metallic piping systems for fluid transfer — including polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) and fiberglass-reinforced plastic (FRP) — instead of exotic metal piping. While non-metallic piping systems have…
