This P-recovery process is market-ready

At PowTech 2019 this month (Nuremberg, Germany), Glatt Ingenieurtechnik GmbH (Weimar, Germany; www.glatt.com) introduced a waste-free process that recycles the phosphorus from sewage-sludge ash to produce ready-to-use, high-quality fertilizers. The market-ready process fulfills the legal obligation of the German fertilizer…

A new membrane for forward osmosis

Many desalination technologies have been developed, but they usually require a large amount of energy. Forward osmosis (FO) has the potential to become an excellent alternative desalination technology due to its lower energy consumption. Nano structured materials have also attracted…

Mechanochemistry performs cross-coupling reactions

Palladium-catalyzed cross-coupling reactions are one of the most powerful and versatile methods to synthesize a wide range of complex functionalized molecules. However, the development of solid-state cross-coupling reactions remains extremely limited. Now, Hajime Itoh, Koji Kubota and colleagues at Hokkaido…

Distillation Column Internals: It’s What’s on the Inside that Counts

New column internals boost efficiency and improve reliability of distillation towers In the chemical process industries (CPI), the majority of separations are done via distillation columns. And, when the rest of the process relies upon those columns, inefficiencies, bottlenecks and…
