Editor’s page: Welcome to Chemical Engineering
This month’s column gives a brief overview of the Chemical Engineering brand. While long-term readers need no introduction to the magazine, newer readers might be interested in the history of the magazine and what we cover. Perhaps even long-term readers…
Focus On: Pumps
A dispenser for abrasive and viscous fluids NEMO dispensers (photo) are designed for precise dosing and metering of abrasive and viscous fluids. With the ability to handle a wide range of viscosities, shear-sensitive materials and entrained solids, NEMO dispensers deliver…
Switchable solvent supports freshwater extraction from hypersaline brine
Extremely high-salinity water streams present difficulties for many types of processing equipment, such as membranes and filters, and most commercial treatment methods involve thermal evaporators or crystallization, which are energy-intensive and require special anti-corrosion materials. A new membrane-less, non-evaporative process…
Makeup Water Treatment: Sodium Softening and Reverse Osmosis
Conscientious operation and maintenance is critical for steam-generator system reliability. Here, important details for softening and reverse osmosis systems are explained and compared As steam generation technology and higher pressure and temperature boilers evolved in the 20th century, improved makeup-water-treatment…
Avenues for Decarbonizing the Steel Industry
Energy- and carbon-intensive, steel production is categorized as one of the most “hard-to-abate” industries, making the scaleup of decarbonization technologies crucial not only for steelmakers themselves, but for every downstream industry in the supply chain Responsible for some 9% of…
Carbon dioxide removal combined with desalination
Most existing carbon-dioxide removal (CDR) approaches have focused on air, but the volumetric concentration of dissolved inorganic CO2 in surface water is much higher (150X) than its concentration in the atmosphere. Removing CO2 from water could prove to be a…
A platform technology for low-carbon cement makes progress
Two recent developments at Queens Carbon Inc. (Pine Brook, N.J.; www.queenscarbon.com), a spinoff company from Rutgers University (New Brunswick, N.J.; www.rutgers.edu), illustrate the potential for reducing the high carbon-dioxide emissions that result from cement and concrete production. Both are results…
GEA commissions new spray dryer at Chugai Pharmaceutical in Japan
GEA (Düesseldorf, Germany; www.gea.com) is supplying Chugai Pharmaceutical in Japan with a cutting-edge pharmaceutical spray dryer designed and built to meet the highest containment standards. The PSD-3 spray dryer was successfully commissioned in the first quarter of 2025 and represents…
Beyond the Datasheet: Common Pitfalls in Specifying Pressure-Relief Valves
Even seasoned engineers can fall into the trap of trusting valve datasheets too much. In real chemical‑processing environments, “on paper” performance can fall short — especially when factors like backpressure, fluid phase, fire exposure, or piping layout are misunderstood. This…
