One of the key components in the operational success of chemical process industries (CPI) facilities is the transfer pump. These pumps must handle a wide variety of materials under a broad range of operating conditions. These diverse operational conditions may…
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…
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…
Metabolix Inc. (Cambridge, Mass.; www.metabolix.com) has successfully demonstrated and completed research and development for scaleup on a fermentation process that produces gamma -butyrolactone (GBL) from genetically engineered bacteria. The process is built upon the company’s technology for engineering metabolic pathways…
Since the isolation of graphene by the “Scotch tape” method, many researchers have tried to synthesize solution-dispersible graphene. The challenge has been to develop a high-yield method that can exfoliate graphite efficiently into solution-dispersible graphene sheets without collateral damage to…
Today only a few percent of Canada’s oil sands resource is accessible by traditional surface mining, so the rest has to be recovered in situ, mostly by steam-assisted gravity drainage (SAGD). In this process, steam is injected into a horizontal…
