The E-finity (photo) is a continuous, dense-phase conveying system for fragile materials. Precise pressure monitoring and airflow corrections allow the system to operate efficiently under a wide range of conditions, while gently inducing materials through the conveying line in slug…
The MagnaShear motor brake (photo) employs oil shear technology that transmits torque between lubricated surfaces, thereby preventing wear on friction surfaces. A patented fluid-recirculation system dissipates heat, eliminating heat buildup, which is the most common problem in dry braking systems.…
The new Allen-Bradley Micro 870 programmable logic controller (PLC; photo) can support applications that require up to 304 I/O points, 280 kB of memory and 20,000 program instructions. The Micro870 PLC uses a flexible design concept that provides designers up…
The activated sludge process (ASP) is designed to speed up the rate of decomposition of waste material in water. First developed in 1914, it remains an important means of treating both municipal and industrial wastewaters. This one-page reference provides information…
The new 1209 pressure gage (photo) is equipped with a 316L stainless-steel solid front case and ring, along with a pressure-relief back cover to ensure that the process fluid will be directed away from the operator in the event of…
The Rosemount CX1100 in-situ oxygen analyzer (photo) is said to be the first high-performance, zirconia-cell-based combustion-control system designed to improve energy efficiency and meet environmental regulatory requirements for small and midsize boilers. It features the same sensor reliability found in…
The CGM 750 (photo) is a new cone mill with a diameter of 29.5 in. (750 mm) that gently grinds fatty, heat-sensitive, sticky, moist or fragile materials into uniform particle sizes with minimal fines at rates up to 32 metric…
This company’s Sanipacking fills (photo) prevent the growth of bacteria and reduce the risk of Legionella bacteria in wet cooling towers with open circuits. Sanipacking fills also prevent colonization of the fill surface by the microbe Pseudomonas aeruginosa, the species…
The CL 10HY-V2 density cell and Series 2000 density digital converter (photo, p. 37) can be used to measure the density of ammonium hydroxide, caustic soda, ethylene glycol, methanol, nitric acid, oleum, phosphoric acid, sodium chloride and sodium hydroxide. The…
A process that produces renewable hydrogen from organic biowaste and reduces the economic and environmental burden of wastewater treatment is being developed by Chemergy, Inc. (Miami Fla.; www.chemergy.com). Introduced at last month’s AIChE Spring Meeting (April 22–26; Orlando, Fla.), Chemergy’s…
