Looking at the challenges and benefits of various recycling technologies, this article uses polymethyl methacrylate (PMMA) as an example to analyze the economics and design considerations for depolymerization processes Plastics are a valuable commodity in society and provide versatile materials…
Concrete production is responsible for 6–9% of global anthropogenic CO2 emissions. “The largest contribution to that comes from the production of cement, a precursor product,” says Peter Stemmermann from the Institute for Technical Chemistry (ITC) at the Karlsruhe Institute of…
At Achema 2024 (Frankfurt, Germany; June 10–15), Sulzer Chemtech (Winterthur, Switzerland; www.sulzer.com) revealed MellapakEvo (photo), the latest addition to its structured-packing product family. The MellapakEvo structured packing has been developed to enhance the efficiency and capacity of distillation columns, maximizing…
Process heating systems are critical parts of chemical process industries (CPI) facilities. Unfortunately, the reliable, efficient operation of utility systems is often taken for granted, and they receive little engineering attention. This is perhaps understandable, since these systems play a…
The NEMO MY magnetically coupled pump (photo) is the latest upgrade of the NEMO progressing-cavity pumps. It was developed for more efficient and safer handling of media with high viscosities (up to 20,000 cP), such as slurries. However, using the…
The costs associated with installing and maintaining pressure-relief valves (PRVs) can often be reduced by equipping systems with upstream rupture discs Reclosing pressure-relief devices, commonly referred to as pressure relief valves (PRVs), are designed to allow for the release of…
Three of the critical aspects of dust collection systems are properly identifying necessary dust capture points, effectively capturing dust at each point and accounting for solids loading in the ductwork. Key considerations for these aspects are presented here Dust collection…
Updated digital technology to support field workers The updated Ability Connected Worker technology (photo) offers new functionalities that strengthen and accelerate the digitalization of the field-operator experience to mitigate the risk of human error and unscheduled downtime. The enhanced software…
This company has earned the UL 508A certification for its pneumatic vacuum-conveyor controls (photo). Secured to support operator safety and help speed the conveyor installation process, the certification documents conformance with the National Electric Code (NEC) standard for the safe…
A new bulk-bag unloading station features a proprietary design that promotes the smooth, consistent, complete discharge of non-free-flowing materials. Developed for emptying difficult bagged powders and other bulk materials that cake, clump, bridge or generate nuisance dust, the new AFC…
