In the framework of the Impulse project (Integrated Multiscale Process Units with Locally Structured Elements; CE, April 2005, p. 19), researchers from the Industrial Chemistry Group at RWTH Aachen University (Germany; www.itmc.rwth-aachen.de) have developed a continuous production plant capable of…
Mitsubishi Chemical Corp. (MCC; Tokyo, Japan; www.m-kagaku.co.jp) has developed a new technology for producing 1,3-butadiene (butadiene) from waste butenes using a self-developed, proprietary catalyst. The process has been pilot tested (200-ton/yr capacity) at MCC’s Mizushima site in Japan, and the…
A less-expensive way of making the raw materials for carbon anodes (for aluminum smelting) and graphite electrodes (used to make steel in electric arc furnaces) has been developed by West Virginia University (UWV; Morgantown, W.Va.; www.wvu.edu). The conventional starting materials…
A photocatalyst that is more active for decomposing volatile organic compounds (VOCs) with visible light than existing catalysts has been developed by researchers from the New Energy and Industrial Technology Development Organization (NEDO; Kawasaki City, Japan) in a project lead…
Vesta Tank Bottom Valves are used to shut off liquid media at vessels or tanks. Preferably installed at the lowest point of the tank bottom, their characteristic feature is shut-off at tank bottom level without any sump. The pocket-free design…
The Analysette 22 MicroTec Plus is the latest generation of this company’s particle measurement technology. The instrument covers a range of 0.08 to 2,000 µm with a resolution of up to 108 measuring channels. The wet dispersion unit is equipped…
The Helical Dryer series HD was designed to meet the requirements of multipurpose production, as specified by a study group that included major European pharmaceutical manufacturers. The dryer incorporates an optimized mixing assembly, which features a mechanical seal (without product…
Electromechanical (EM) pumps are widely used in wastewater and sewage treatment, chemical and ceramic industries, mining, power plants, marine and offshore applications. With RAN EM diaphragm pumps, capacities up to 30 m³/h can be transferred. Body material options are aluminum,…
Designed for pumping hazardous and chemically aggressive liquids, this seal-less PTFE/PFA-lined chemical pump complies with DIN EN 22858 and Atex. The pump provides virtually leak-free operation and unrestricted corrosion resistance, even at temperatures of 160°C and higher. The pump features…
Friction Factor Fluid flowing through pipes experiences resistance due to viscosity, turbulence and roughness of the pipe surface. The Darcy-Weisbach Equation (1) is commonly used for the analysis of steady-state, Newtonian-fluid flow inside pipes. It summarizes the relations between frictional…
