Most engineers know what viscosity is, but may have trouble explaining it. To be brief, viscosity is resistance to flow. For handlers of all materials that flow, either while being processed or in an end-use, it is important to think…
Substantial technological advances to meet the growing regulatory scrutiny of a wide variety of pollutants have taken place over the past 50 years. In the last few years, the increased complexity in regulations in developed countries has been even more…
Many branches of the chemical process industries (CPI) make use of impact comminution to process solid matter, such as minerals, foodstuffs, pharmaceutical products, and above all, products for the chemicals industry. Impact comminution is also used for coarse crushing, but…
Successful adsorber design requires information about certain adsorbent properties, including: adsorbent densities and void fractions; isotherms or other equilibrium data; and data on mass-transfer kinetics and fixed-bed dynamics. Here, these adsorbent properties are explained, along with corresponding equations. Densities and…

Despite the immense value and universal appeal of these additives for product designers, process engineers facing the day-to-day reality of full-scale production face a unique set of challenges. Dispersing these powdered additives into a liquid is one of the most…
“When you improve the efficiency or capacity of a product, it almost always can be used to improve the process economics with respect to investment costs or operating costs,” says Mark Pilling, manager of technology with Sulzer Chemtech (Tulsa, Okla.).…
Examine reaction kinetics and more with this system With integrated mid-infrared (IR) capabilities, the fully automated Atlas FT-IR System (photo) for reaction monitoring combines the technology of the Atlas automated reactor with Bruker Optics’ Matrix-MF, a process-ready fourier transform infrared…
A new range of dosing pumps This firm now offers four new series of multilayer diaphragm pumps and piston diaphragm pumps featuring the multilayer diaphragm technology. These include two series for local, manual control (R-Series) and two series with integrated…
Tie-in opportunities are few and far between. These rules of thumb will help make sure everything and everyone line up in time A majority of capital projects today are either debottlenecks or revamps that are intended to increase capacity, squeeze…
