Rate-limiting Mechanisms of Water Removal during the Formation, Vacuum Dewatering, and Wet-pressing of Paper Webs: A Review

open access: yesBioResources, 2020
Because some of the critical events during the removal of water before the dryer section on a paper machine happen very rapidly within enclosed spaces – such as wet-press nips – there have been persistent challenges in understanding the governing ...

Enhancing the Stability and the Scalability of Tree‐Mimicking Dewatering Devices by Employing Hygroscopic Cellulose

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 1, January 2026.
A hygroscopic cellulose implemented as an artificial stem markedly facilitates the surface evaporation in artificial tree devices and greatly enhances the device stability. The direct enhancement of surface evaporation rate by leaf area increase is demonstrated.

Liquid–liquid equilibrium studies of n‐butane–bitumen system with application to solvent‐aided in situ bitumen recovery

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 1, Page 425-441, January 2026.
Abstract Solvent‐assisted recovery methods have gained attention as an alternative to conventional thermal methods which have significant environmental drawbacks and high greenhouse gas emissions. Solvent‐assisted recovery methods can lead to various phase equilibria, such as vapour–liquid equilibrium (VLE) and liquid–liquid equilibrium (LLE), under ...

Preparation of coal slurries deposited in ground settling ponds [PDF]

open access: yes, 2005
As a result of the hard coal washing process, considerable quantities of coal slimes are generated. They belong to grain size classes below 1, 0 mm (with the majority of grains below 0,035 mm) and are often sold in order to prepare blends for the power ...
