The new CO2 Feed System (photo) is a safe and effective way to adjust pH and minimize risk associated with dangerous mineral acids. The 0–100% scaled flowmeter has an integral adjustment needle valve for increased accuracy. Additional benefits of the…
With the Texoversum (photo), Reutlingen University (Germany; www.reutlingen-university.de) has put into operation a training and innovation center for the textile industry that is unique in Europe. The almost 2,000-m2 textile-like façade of the new building combines the innovative power of…
There are several established technologies to remove per- and polyfluoroalkyl substances (PFAS) from water, including membranes and adsorbents. However, such purification media can pose disposal challenges due to the potential for further PFAS contamination stemming from the spent media. Now,…
For intelligent textiles to function effectively, they need to be strong, stretchable and electrically conductive. However, fabricating fibers that possess these three properties has been challenging. Drawing inspiration from how spiders spin silk to make webs, an international team of…
Last month, Circa Group A/S (Oslo, Norway; www.circa-group.com) applied for patents for two new solvents for CO2 capture processes. The solvents, named Furatech:1 and Furatech:2, were developed over the last 12 months as part of the company’s platform molecule, levoglucosenone…
Crushing and screening of solids are essential to many solids-handling processes, but engineers must be mindful about how those actions will affect flow behavior of the bulk material When it comes to processing bulk solids, (particle) size matters. Almost all…
This company has engineered a purpose-built VM-450-gallon VersaMix (photo) that features three independently driven agitators, including a two-wing center-mounted agitator with contoured bottom and Teflon scrapers to efficiently motivate viscous product throughout the mixing zone, a long helical flight agitator…
Henry Kister shares lessons learned from troubleshooting distillation towers During a course that I was presenting in Houston one year, a participant asked me the following at the end of one of the sessions: “Do you have experience with BX-type…
The proper selection of materials of construction is crucial. The example presented here shows how to use standards to help narrow down the options Since the late 1800s, a steady body of pressure technology codes and standards have been under…
An overview on the importance of standard operation procedures (SOPs) and how to write them Today, it is necessary to have standard operating procedures (SOPs) for steam and condensate systems, boilers, deaerators and even steam process units (Figure 1). An…
