On-line phase holdup measurement and analysis in flotation columns

open access: yes, 1994
A technique for on-line simultaneous determination of gas and solids holdup, based on a combination of conductivity and pressure difference measurements, was developed and tested in a laboratory flotation column (10 cm in diameter and 447 cm in height ...

Modelling of transient gas-liquid flow and pigging in pipes [PDF]

open access: yes, 1999
More and more transient gas-liquid operations in pipes are being successfully applied in the oil and gas industry. Pigging in two-phase pipelines, to remove liquid accumulation or for cleaning purposes, is an important transient operation.

The Finite Element Analysis for a Mini-Conductance Probe in Horizontal Oil-Water Two-Phase Flow

open access: yesSensors, 2016
Oil-water two-phase flow is widespread in petroleum industry processes. The study of oil-water two-phase flow in horizontal pipes and the liquid holdup measurement of oil-water two-phase flow are of great importance for the optimization of the oil ...

Liquid Holdup in Geothermal Wells [PDF]

open access: yes, 2020
Simulation of two-phase flow in geothermal wellbores requires use of empirical correlations for liquid holdup and for friction factor. Use of currently available correlations often yields widely differing results for geothermal wells. A new liquid holdup

Prediction of Liquid Holdup and Solid Holdup in Three-phase Fluidized Bed: Air/Newtonian and non-Newtonian Liquid Systems

open access: yes, 2008
Three-phase fluidizing beds have emerged in recent years as one of the most promising devices for three-phase operations. Such a device is of considerable industrial importance in chemical and biochemical industries, wastewater treatment and other ...

A simple correlation for prediction of the liquid slug holdup in gas/non-Newtonian fluids: Horizontal to upward inclined flow

open access: yes, 2013
This paper studies the liquid slug holdup of gas/non-Newtonian fluids in horizontal and inclined pipes. The results of the study show that the liquid slug holdup significantly increases for a given mixture velocity as the liquid phase becomes ...

Computational Fluid Dynamics Simulation and Experimental Measurement of Gas and Solid Holdup Distributions in a Gas-Liquid-Solid Stirred Reactor

open access: yes, 2015
The lack of convincing computational fluid dynamics models and basic experimental data makes it difficult to design and scale up a gas liquid solid three-phase stirred reactor such as in environmentally benign bioleaching processes.

Experimental Investigation of Liquid Holdup in a Co-Current Gas–Liquid Upflow Moving Packed Bed Reactor with Porous Catalyst Using Gamma-Ray Densitometry

open access: yesChemEngineering
This study explores the dynamics of liquid holdup in a lab-scale co-current two-phase upflow moving packed bed reactor, specifically examining how superficial gas velocity influences the line average external liquid holdup at a fixed superficial liquid ...
