The prices of low-voltage variable frequency drives (VFDs) have declined substantially since they were introduced, while the cost of power has increased. Normal project economics will now justify these VFDs — which go up to 375 kW (500 hp) or…
Many CPI applications require the injection of chemicals, such as corrosion inhibitors, precipitation inhibitors, oxygen scavengers and countless others, into the process during operation. Follow these tips to design and operate a system that ensures accurate delivery of performance chemicals,…
The new V Series modulating ball valve is designed for controlling pressure, temperature flow and level. The valve body is available in carbon or stainless steel with NPT, Socket Weld, Tri-Clamp and 150# or 300# flanged end connections. Sizes are…
The first international “Science Award Electrochemistry” from BASF SE (Ludwigshafen; www.basf.com) and Volkswagen AG (Wolfburg; both Germany; www.volkswagen.com) goes to Dr.Naoaki Yabuuchi, Tokyo University of Science, Institute for Science and Technology (Tokyo, Japan). The jury of experts from BASF, Volkswagen…
Fans and blowers are common in air-handling and movement systems used in the chemical process industries (CPI). Two major uses of fans and blowers are in pneumatic conveying systems and in ventilation and air-pollution-control systems. Powering fans and blowers can…
Inorganic acids play a major role in the chemical process industries (CPI). They are used as raw materials, catalysts or finishing and pH control agents in the manufacture of a wide range of chemical products, from fertilizers to detergents, and…
Small chemical reactors offer a number of benefits compared to large reactors, such as better heat transfer and mixing. While small batch vessels are impractical at the industrial scale, continuous flow reactors can provide the benefits of small physical size…
The QVF Supra-Line is compatible with two proven flange systems — the QVF/WPR2002 and the Schott/KF systems — and thus reduces the number of technically equivalent components required while providing the user with increased safety. The Supra-Line extends the allowable…
The new Pivotrol PTF4 is a high-capacity, pressure-powered condensate pump that covers a wider motive-pressure range. This new version can be operated by steam, air or other pressurized gases, and covers a complete pressure range of up to 200 psig.…
Air Fuel Synthesis Ltd. (AFS; Darlington, U.K.; www.airfuelsynthesis.com) has recently demonstrated a process for producing carbon-neutral liquid hydrocarbon (HC) fuel from air-captured carbon dioxide and hydrogen. The proof-of-concept demonstration facility, located at Teesside, England produces 5–10 L/d of liquid HCs.…
