Modulation of liquid holdup along a trickle bed reactor with periodic operation
(Pergamon-Elsevier Science Ltd, 2007-11)
Temporal variations of the liquid holdup in a mini-pilot scale trickle bed reactor cold-mockup, induced by an ON-OFF liquid flow modulation strategy of operation, are explored at different axial positions. The reactor is ...
Electrode arrangements for continuous measurement of dispersion conductivity in lab flotation cells
(Elsevier, 2017)
Electrical conductivity, an intensive property of materials, has been used in flotation for measuring important process variables such as froth depth, bias rate, solid and gas holdup. Most of these applications were based ...
Methodological analysis of gamma tomography system for large random packed columns
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Gamma ray tomography experiments have been carried out to detect spatial patterns in the porosity in a 0.27 m diameter column packed with steel Rashig rings of different sizes: 12.6, 37.9, and 76 mm. using a first generation ...

Holdup models from experimental conductance data in a bubble column
(Pergamon-Elsevier Science Ltd, 2001-02)
Mathematical models for the calculation of gas holdup in liquid-gas systems from experimental measures of the electrical conductance at several frother levels are presented in this paper. Experimental data were taken by a ...
Gas holdup and rtd measurement in an industrial flotation cell

The role of governmental commitment on regulated utilities
(Elsevier, 2019-10-09)
Regulation is generally interpreted as a relational contract between governments and private companies. Besides, regulation plays either a positive or a negative role in infrastructure development. This article is intended ...
