Feature Report: Incorporate Floating Solids Into Liquids
The incorporation of floating solids into liquids is a common challenge throughout the chemical process industries (CPI) in operations ranging from polymerization reactions to fermentation processes and water treatment. Yet, it has received much less attention in comparison to processes…
Chementator: Catalyst loading
TubeMaster, Inc. (Louisville, Ky.; edlinks.chemengonline.com/7373-547) has filed U.S. and foreign patents for Dog-leg — claimed to be the world’s first articulating catalyst-loading device that permits loading of single and multi-layer catalyst to any height or outage, regardless of reactor vertical-head…
Solids Processing: Blender Selection And Avoidance of Post-Blender Segregation
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…
Vacuum Injection of Powders in the Center of the Emulsifier
Several manufacturing procedures for chemical, cosmetic, pharmaceutical or food products distribute powder-like solids during the liquid or pasty phases of operations. The systems usually used for these operations require the injection of powders in an agitation tank. Dispersion is often…

Tank Coatings: Covering the Basics of Selection and Specification
The interior surfaces of your storage tanks are constantly at risk. If you walk past a tank often without giving thought to what is happening on the inside, it is because you trust the interior coating to protect not only…
Chementator: Resodyn Unveils ‘Entirely New’ Mixing Technology
At the Chem Show last month (New York; Oct. 30 – Nov. 1), Resodyn Acoustic Mixers Inc. (Butte, Mont.; edlinks.chemengonline.com/6902-531) demonstrated its new, impeller-free mixing technology, which induces microscale turbulence through the propagation of acoustic waves. Dubbed ResonantAcoustic Mixing (RAM),…
Solids Processing: Weighing Your Options — The 10 Most Important Scale Considerations
Scales are available in a dizzying array of types and sizes to suit different needs. Although it’s easy to default to price in order to eliminate the tedious task of researching your options, a basic knowledge of these ten key…
Microbial testing
A molecular testing method that attains a viable count of microbial organisms in as little as 4 h compared to the typical 3–14 d needed by standard methods, has been commercialized by Lonza AG (Basel, Switzerland; edlinks.chemengonline.com/6901-544). The genetics-based (RNA…
