Recent advances in gas-monitoring technologies can greatly increase worker connectivity and safety With increased automation, expanding areas of operation and smaller teams of field workers, monitoring personnel and ensuring lone worker safety are serious challenges for the chemical process industries…
‘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…
In late February, construction began on a test facility that will be used to demonstrate a CO2-capture process being developed by JGC Corp. (Yokohama, Japan; www.jgc.com) and Japan Oil, Gas and Metals National Corp. (JOGMEC; Tokyo; www.jogmec.go.jp). When the Texas-based…
The novel performance characteristics and tunability of quantum dots make them a promising nanomaterial in numerous emerging applications Quantum dots (QDs) represent a broad group of semiconducting nanoparticles that feature a unique combination of optical and electronic properties. For example,…
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…
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…
