Spherical ‘chip’ extends H2 sensor range a hundredfold

A prototype of what is called the world’s fastest, wide-ranging hydrogen gas sensor has been constructed by a team of researchers, led by Professor Kazushi Yamanaka at the Dept. of Materials Processing, Tohoku University (Sendai, Japan; edlinks.chemengonline.com/5828-531), together with Toppan…

EDDL standards continue to evolve

The EDDL (electronic-device-description language) Cooperation Team (ECT; Karlsruhe, Germany; edlinks.chemengonline.com/5828-532) has released Phase 1 EDDL enhancement specifications. The enhancements on the existing EDDL include new capabilities, such as graphs, charts and images, the possibilities for archive data, and an EDD…

This flowmeter now has a FF massflow-function block

Last month, Emerson Process Management (St. Louis, Mo.; edlinks.chemengonline.com/5828-540) launched the Rosemount 3095 MultiVariable transmitter with FOUNDATION Fieldbus (FF) technology and fully-compensated mass-flow functionality. Said to be a first for the process industries, this extension to the Rosemount 3095 platform…

Integrating CFD & DEM

Fluent. Inc. (Lebanon, N.H.; edlinks.chemengonline.com/5828-541) has entered a partnership with DEM Solutions (Edinburgh, U.K.; edlinks.chemengonline.com/5828-542) to complement Fluent’s multiphase computational fluid dynamics (CFD) models with discrete-element-modeling (DEM) capabilities. DEM Solution’s EDEM software enables engineers to simulate the behavior of particuate…

Focus On: Pressure Measurement

These miniature regulators are ideal for gas instruments The compact DM3000 (photo, left) allows flow control systems for process or laboratory instrumentation to be constructed in small spaces. With a flow coefficient (Cv) of 0.1 and a maximum inlet pressure…

Chementator: New software should speed up reaction engineering

Simulations of chemical processes that involve many reactants with continually changing compositions can be set up and run in minutes, rather than the previously required hours, with a newly commercialized software package, Reaction Engineering Lab, says developer Comsol (Stockholm, Sweden,…

Minimize Trapped Components in Distillation Columns

Minor components trapped in distillation columns can react to form solids that cause major problems. The conventional responses to this situation focus upon dealing with the solids after they have become formed. A better strategy consists of preventing or minimizing…
