A System Approach with Flow Analysis

Taking a system approach to find the root cause of a problem can be more beneficial than simply replacing a problematic pump. This article explains why We want the best reliability with anything that we work with. In a plant…

Field Calibration of DP Flowmeters: Best Practices

Improved understanding of differential pressure (DP) flowmeter operation, along with best calibration practices, reduces maintenance errors Utilizing an orifice plate installed in a pipe and accurately measuring the differential pressure (DP) to calculate flow is one of most common methods…

A flexible, origami-based fuel cell

Until now, manufacturing polymer-electrolyte membrane fuel cells (PEMFCs) that are small, light and capable of mechanical movement has been challenging using conventional methods. PEMFCs are composed of end plates, bipolar plates, gaskets, membrane-electrode assemblies (MEAs) and other assembly parts, of…

A solvent-free process makes battery electrodes

Conventional processes for manufacturing battery electrodes use toxic solvents and require a lot of space and energy. In contrast, DRYtraec — a new dry-coating process developed by the Fraunhofer Institute for Material and Beam Technology (IWS; Dresden, Germany; www.iws.fraunhofer.de) —…

Chementator briefs

'New food' GEA AG (Düsseldorf, Germany; www.gea.com) has received a contract from Novozymes A/S (Copenhagen, Denmark; www.novozymes.com) for a turnkey fitting of a major new plant to produce plant-based proteins for the plant-based food industry. The high double-digit million-euro order…

Two new semiconductor-based nanomaterials synthesized for the first time

The latest generations of computer chips are only a few nanometers in size and are becoming ever more energy-saving and powerful as a result of progressive miniaturization. Since the etching processes traditionally used in chip production are increasingly reaching their…

Integration of CO2 direct air capture and alcohol-to-jet fuels manufacturing

A feasibility study is underway for the world’s first commercial facility that integrates direct air capture (DAC) of atmospheric carbon dioxide with gas fermentation of CO2 and production of aviation fuels. LanzaTech (Chicago, Ill.; www.lanzatech.com) and Carbon Engineering (Squamish, B.C.;…

Safer, more sustainable control of runaway polymerization

Runaway polymerizations of acrylic monomers can lead to catastrophic fires and explosions in production plants and storage terminals, as well as during transportation. Special chemical products called shortstop inhibitors are used to minimize the likelihood of runaway polymerization reactions. A…

CE Podcast: Swagelok engineers discuss grab-sampling

In this episode of the Chemical Engineering podcast, senior editor Scott Jenkins speaks with Matt Dixon and Karim Mahraz, both engineers at Swagelok and experts on grab-sampling systems. Matt and Karim discuss the most common problems associated with grab sampling…
