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…

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…

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…

Stress Analysis for Piping Systems Resting on Supports

    Piping-flexibility and stress analysis are required in the design of most piping systems before the piping is installed in a chemical-process or other plant. It is intended to ensure the safety of the plant and thus protect the…

Modeling gas-liquid separation

Process System Enterprise Ltd. (PSE; London, U.K.; edlinks.chemengonline.com/5825-542) has launched the latest of a series of gPROMS Advanced Model Libraries (AMLs) for Gas-Liquid Contactors (GLCs). This “open model” library of high-fidelity, non-equilibrium-component models covers a wide range of gas-liquid-separation operations,…

KEEP TABS ON VALUED PLANT ASSETS

Asset management means different things to different people, but in the chemical process industries (CPI) it’s all to do with making the most of expensive equipment. Asset management is frequently used as another term for maintenance, especially of the proactive…

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…
