[HTML][HTML] Quasistatic model for foam fractionation

P Grassia - Chemical Engineering Science, 2023 - Elsevier
A simple model is presented for foam fractionation. The basis of the model is that the liquid
fraction profile across the foam column is known quasistatically at any instant in time, and …

[HTML][HTML] A model for foam fractionation with spatially varying bubble size

P Grassia, C Torres-Ulloa - Chemical Engineering Science, 2023 - Elsevier
A model is developed for a foam fractionation process, supposing that bubble size increases
moving up the foam column. Predictions are obtained for liquid flux through the foam …

Impact of the lubricant on a modified revolving vane expander (M-RVE) in an organic Rankine cycle system

A Naseri, R Moradi, L Cioccolanti, A Subiantoro - Energies, 2023 - mdpi.com
The expansion device is the critical component of micro-to-small scale organic Rankine
cycle (ORC) systems, substantially affecting system efficiency and cost. Low isentropic …

[HTML][HTML] Transport of convected soluble surfactants on and within the foam film in the context of a foam fractionation process

H Rajabi, R Rosario, P Grassia - Chemical Engineering Science, 2023 - Elsevier
This study models convective transport of soluble surfactant in a foam fractionation system
with reflux. Owing to reflux, initial surfactant concentration in films is lower than in Plateau …

Drainage in a rising foam

P Yazhgur, E Rio, F Rouyer, F Pigeonneau, A Salonen - Soft matter, 2016 - pubs.rsc.org
Rising foams created by continuously blowing gas into a surfactant solution are widely used
in many technical processes, such as flotation. The prediction of the liquid fraction profile in …

Theoretical analysis of the performance of a foam fractionation column

ST Tobin, D Weaire, S Hutzler - Proceedings of the …, 2014 - royalsocietypublishing.org
A model system for theory and experiment which is relevant to foam fractionation consists of
a column of foam moving through an inverted U-tube between two pools of surfactant …

Maintaining yeast viability in continuous primary beer fermentation

EJ Pires, JA Teixeira, T Brányik… - Journal of the …, 2014 - Wiley Online Library
Continuous fermentation is a long known and vastly studied process. The use of
immobilized cell technology (ICT) is exploited in a significant number of studies owing to the …

Modelling surface active species transport during a foam fractionation process with reflux

H Rajabi - 2023 - stax.strath.ac.uk
Surface active species can be encountered in various process industries. This can then
result in demand for their separation. Most of the conventional separation methods are …

[图书][B] Foam Fractionation of surfactant-protein mixtures

ID Kamalanathan - 2015 - search.proquest.com
