Messer Group GmbH (Krefeld, Germany; edlinks.chemengonline.com/6516-531) has commercialized a liquid-nitrogen- (LNâ‚‚) based process for purifying exhaust air that contains high (100–1,000 g/m3) loads of chlorofluorocarbons (CFCs) or solvents. Unlike incineration (which can have problems, such as dioxin formation, with chlorinated…
Solid-liquid separation is a key unit operation that processors look to for a wide-range of applications ranging from: the lowly removal of debris from cooling-fluid lines and products; through the recovery of product from solvents; to massive-scale dewatering…

Researchers from the Physics of Fluids and Biocolloids group at the University of Granada (Spain; edlinks.chemengonline.com/6516-549) are developing a system in which bitumen emulsifies at room temperature, which facilitates transport and allows cold application. Because the bitumen does not need…
ADA-ES, Inc. (Littleton, Colo.; edlinks.chemengonline.com/6516-550) has been awarded a contract from the U.S. DOE to develop an improved process for manufacturing activated carbon (AC). AC is the key chemical used in ADA-ES’s mercury-control technology (CE, December 2004, p. 18) —…
Low flowrates can be measured with these sensors Models 104 and 107 Liquid Flo-Sensors are designed as an electronic alternative to ball-and-tube rotameters and can measure fluid flowrates as low as 13 mL/min. Stainless-steel construction offers compatibility with…
Pick one of ten sensors to track exposure to hazardous gases There are now ten different contaminant-specific sensors available for this firm's Pac 7000 single-gas detector (photo). Depending on which sensors are fitted, the device can reliably announce…
A chemical-treatment process, called Kemicond, that reduces the volume and odor of sludge has been commercialized by its developer Kemitra Kemi AB Kemwater (Helsingborg, Sweden; edlinks.chemengonline.com/6515-532). The first commercial application - a system for Käppala Association (Stockholm, Sweden) that treats…
