A Short‐Cut Design Approach to Evaluate Reboiler Designs in Vapor Recompression Scenarios

open access: yesChemie Ingenieur Technik, EarlyView.
A short‐cut model framework that incorporates mechanical vapor recompression (MVR) requirements into reboiler design is presented, which is particularly beneficial during early process development with limited data or initial feasibility assessments.

Application of Ultrasonic Sensors for Determining the Height of Dynamic Two‐Phase Layers in Tray Columns

open access: yesChemie Ingenieur Technik, EarlyView.
Ultrasonic sensors are evaluated for their applicability in dynamic gas–liquid systems. By comparing sensor data with two independent optical reference methods, their robustness and reliability are demonstrated under varying flow conditions and tray geometries in column systems.

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...

Être Écossais, un entre-deux permanent ? Réflexions sur le pluralisme identitaire dans un État d’union

open access: yesTextes & Contextes
L’identité écossaise constitue un entre-deux car l’Écosse, indépendante jusqu’au XVIIe siècle, a conservé de nombreuses spécificités en formant la Grande-Bretagne à l’issue d’une union législative avec l’Angleterre. Cette

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

open access: yesDroplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...
