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…

Implementing digital transformation

The recently concluded 5th annual Connected Plant Conference (CPC; www.connectedplantconference.com), held in Austin, Tex., illustrated both the real promise of Industry 4.0 digital tools to improve operational efficiency and safety at chemical process industries (CPI) facilities, as well as the…

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…

Proof-Testing Level-Measurement Devices in Storage-Tank Safety Systems

Storage tanks containing hazardous materials require safety instrumented systems (SIS) to prevent overfills. Digital technology in the latest level-measurement devices used in SIS enables remote proof-testing, which provides significant advantages At industrial facilities with tanks containing hazardous, flammable or explosive…

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…

Expanding access to real-time monitoring technology for polymer reactions

A recently announced business collaboration between Fluence Analytics (Houston; www.fluenceanalytics.com) and Yokogawa Corp. (Tokyo, Japan; www.yokogawa.com) will significantly expand the availability of the latest generation of Fluence’s technology for continuous, real-time monitoring of polymerization processes. Under the agreement, the two…

Membrane productivity springs forward with new degradation-control method

The ability to precisely control the molecular structure of polymer membranes could expand their use in challenging separations, such as the purification of xylene isomers. Using highly selective membranes that can be operated at ambient conditions to separate such hydrocarbons…
