For petroleum refineries, the cost of converting hydrofluoric-acid-based alkylation units to the relatively safer sulfuric-acid-based alkylation process (diagram) has been cost-prohibitive and has lacked specific economic benefits. Now, DuPont (Wilmington, Del.; www.dupont.com) has developed a low-cost approach to converting existing…
The new ERC25-25 eccentric roll crusher (photo) can process hard rock and ores efficiently and economically in underground mining operations. It features a compact design and an integrated screen that is 20 to 50% lower than conventional primary crushers, a…
A triple-layer, porous membrane system developed at the Functional Materials Laboratory at Eidgenössische Technische Hochschule Zürich (www.fml.ethz.ch) can be fashioned into evaporative curtains to cool and humidify indoor spaces, potentially decreasing the energy demand for climate-control systems. Juxtaposing opposite forces…
Advances in next-generation materials and assembly techniques have enhanced membranes’ effectiveness in numerous applications Membranes are one of the primary technologies used for separations. While they may be best known for their use in water-treatment operations, advances in membrane technologies…
This company recently introduced a magnetic filter (photo) that captures very tiny iron particles (as small as 1µm in diameter) in industrial liquids, such as lubricating oil, solvents and coolants. Removing iron particles from such products reduces damage to machines…
The BinMaster C-100 control console provides level and volume data outdoors at ground level with the push of a button. It is simple to add to a network of up to 120 SmartBob cable-based sensors mounted on bins, tanks or…
Last month, this company introduced the PV4 and PV6 piston valves (photo) for isolation purposes. They are available in NPT and SW versions, in sizes from½ to 2 in., in either forged carbon steel or forged stainless steel. These valves…
This company’s MegaPress stainless-steel press fittings (photo) are said to dramatically reduce the time required to make pipe repairs compared to other pipe joining systems, leading to shorter periods of production downtime. MegaPress fittings are equipped with this company’s patented…
The new TankJet 78 tank cleaner (photo) provides fast, high-impact cleaning of tanks up to 45 ft in diameter. TankJet 78 systems are available in single-hub (two-nozzle) or dual-hub (four-nozzle) designs. The unit is built to withstand extremely harsh chemicals…
The Kek cone mill (photo) can handle a wide range of feed material to produce diverse products for intermediate sizing in both wet and dry granulation processes. According to the manufacturer, the Kek cone mill provides a gentle, low-energy form…
