Hydrodynamic and mass transfer efficiency of ceramic foam packing applied to distillation. [PDF]

open access: yes, 2009
In addition to a high void volume and specific area, solid foams possess other properties (low density, good thermal, mechanical, electrical, and acoustical behaviour) that make them attractive for applications such as heat exchangers and reformers ...

GAS HOLDUP AND AXIAL LIQUID DISPERSION IN THREE PHASE BUBBLE COLUMNS

open access: yesJournal of Engineering and Sustainable Development, 2015
Axial liquid dispersion coefficient was studied in air-tap water systems (bubble columns) and air-tap water-PVC solid particles systems for different column diameters, 10, 15, and 30 cm, Each column had a gas distributor plate with perforated holes of

Experimental investigation on free surface vortices driven by tangential inlets [PDF]

open access: yes, 2016
Particle Image Velocimetry (PIV) measurements have been carried out in order to analyze the structure of free surface vortices in a promoting geometry with two tangential inlets. Velocity fields associated to the free surface vortex have been obtained at

Gas Holdup in a Cocurrent Air-Water-Fiber Bubble Column [PDF]

open access: yes, 2004
Effects of superficial liquid velocity (Ul ), superficial gas velocity (Ug ), and fiber mass fraction (C) on gas holdup (ε) and flow regime transition are studied experimentally in well-mixed water-cellulose fiber suspensions in a cocurrent bubble column.

Characteristics of liquid flow in a rotating packed bed for CO2 capture: A CFD analysis [PDF]

open access: yes, 2017
Rotating packed beds (RPBs) have been proposed as an emerging technology to be used for post-combustion CO2 capture (PCC) from the flue gas. However, due to the complex structure of the packing in RPBs, characteristics of the liquid flow within RPBs are ...

Comprehensive experimental investigation of counter-current bubble column hydrodynamics: Holdup, flow regime transition, bubble size distributions and local flow properties [PDF]

open access: yes, 2016
In this paper, we apply a variety of experimental techniques to investigate the influence of the counter-current mode on bubble column hydrodynamics. We study an air-water bubble column, which is 5.3 m in height and has an inner diameter of 0.24 m, and ...

Effects of Height to Diameter Ratio and Aeration rate on Liquid Mixing and Hydrodynamic Properties in a Bubble Column [PDF]

open access: yesIranian Journal of Chemical Engineering, 2009
"> Experimental measurements of overall gas holdup (εg), residence time distribution (RTD) and liquid mixing time (tm) have been carried out in an air-water system in a 17 lit bubble column with an 11 cm diameter, over a wide range of superficial gas ...

Investigation of the Mass Transfer Ratio in a Bubble Column Operated with Various Organic Liquids and Mixtures Under Ambient Conditions

open access: yesFluids
In this work, for the first time, the dependence of the mass transfer (MT) ratio (kLa coefficient to overall gas holdup) as a function of the superficial gas velocity UG in seven organic liquids was studied.

A model for a countercurrent gas—solid—solid trickle flow reactor for equilibrium reactions. The methanol synthesis [PDF]

open access: yes, 1987
The theoretical background for a novel, countercurrent gas—solid—solid trickle flow reactor for equilibrium gas reactions is presented. A one-dimensional, steady-state reactor model is developed.
