A. Alexander and F. Muzzio, Rutgers University Proper blender selection can improve the mixing of bulk solids. Be sure to consider post-blending segregation problems Mixing and blending of bulk solids occurs frequently in many industrial processes. Though small-scale mixing and…
Plant Watch New chlor-alkali plant scheduled for Kazakhstan April 23, 2008 — Uhdenora received a contract from AO "Kaustik" for a new membrane chlor-alkali plant to be erected in Pavlodar, Kazakhstan. The new plant will have a capacity of 91…
Prevent the growth of germs in water softeners, without heat Water softeners are needed in pretreatment stages for pure-water generators, but they also harbor risks: the ionic-exchange resins offer large surface areas for the growth of microorganisms. A safe and…
Convey tough bulk materials that tend to pack, cake, smear, break apart or fluidize, and prevent separation of blended products Flexible screw conveyors are suitable for use with most bulk materials, from sub-micron powders to large pellets, both free-flowing and…
Water hammer — a high-pressure surge or wave created by the kinetic energy of the moving liquid — is not only a system issue, but primarily a safety concern. Understanding the nature and severity of water hammer in a…
Industrial furnaces, or direct-fired heaters, are only as good as the burners that supply them with thermal energy for heat transfer and endothermic chemical reactions. This article presents equations that permit calculation of such important burner-operating characteristics as flame…
This fifth in a series of articles [1 – 4] on piping design discusses the practical issues of installation and cleaning. Pipe installation The installation of pipe follows its fabrication and is very frequently a part of it. The…
High-resolution x-ray diffraction Based on the Medipix2 application-specific integrated circuit (ASIC), the PIXcel is designed for sensitive, high-resolution x-ray diffraction applications. Consisting of over 65,000 pixels, each 55 x 55 microns in size and with individual readout circuitry, it delivers…
A good understanding of the reaction chemistry is needed for a safe process design It is a fact that safety-related incidents do occur in the chemical process industries (CPI). These incidents have, in part, led to increased attention to reactive-chemical…
A 360° feedback report is a way for employees to learn how they are perceived by direct reports, colleagues, managers, customers, and strategic business partners — hence the term 360° because it generates a "full circle" of information concerning…
