‘Green’ steelmaking Seamlessly following the successful completion of the GrInHy project (Green Industrial Hydrogen via reversible high-temperature electrolysis) in February, the GrInHy2.0 project was launched last month at the Salzgitter Flachstahl GmbH steelworks (Germany; www.salzgitter-flachstahl.de). Together with partners Sunfire GmbH…
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…
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…
A novel carbon-capture project at Michigan Technical University (MTU; Houghton, Mich.; www.mtu.edu) couples the collection of carbon dioxide from power-plant fluegas with a system to use the captured CO2 as a raw material to make oxalic acid, which can be…
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…
A novel and versatile performance chemistry that enables a variety of supramolecular assemblies has been released for its first commercial applications. The molecules, tradenamed AqBit, are characterized by their ringed structures, barrel-like shapes and ability to capture, hold and release…
Adjustment and control of moisture levels in solid materials is a critical aspect in the manufacture of many chemical products. Drying can be defined as the vaporization and removal of water or other liquids from a solution, suspension, or other…
This column is based on “Polyacrylonitrile Production – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/polyacrylonitrile-production-cost. Polyacrylonitrile (PAN) is a polymer resin mainly composed of acrylonitrile. This important acrylic resin is used in the production…
Overpressure in a process can damage the seals in a pressure instrument’s sensor or skew the zero point. Here’s how to avoid the problem Pressure is one of the most commonly measured variables in the chemical process industries (CPI). Accuracy…
Closing off pressure upstream can minimize the need for pressure-relief systems to open, avoiding product waste and possible environmental damage Any system within a chemical process industries (CPI) manufacturing plant that is pressurized, or could experience pressure during an upset…
