Gas holdup and flow regime transition in spider-sparger bubble column: Effect of liquid phase properties [PDF]

, 2017
This paper discusses the effects of the liquid velocity and the liquid phase properties on the gas holdup and the flow regime transition in a large-diameter and large-scale counter-current two-phase bubble column.

A two-fluid model incorporating droplet entrainment to predict pressure drop and holdup for CO2 two-phase flow in horizontal and vertical pipe

Journal of Pipeline Science and Engineering
CCUS technology is currently the best practice for reducing CO2 emissions, with pipeline transportation as the primary method for the long-distance, large-scale transport of captured CO2 to storage sites.

The effect of Alcanivorax borkumensis SK2, a hydrocarbon-metabolising organism, on gas holdup in a 4-phase bubble column bioprocess

, 2023
To design bioprocesses utilising hydrocarbon-metabolising organisms (HMO) as biocatalysts, the effect of the organism on the hydrodynamics of bubble column reactor (BCR), such as gas holdup, needs to be investigated.

Equivalent Dielectric Permittivity Model of Low Water Cut Oil-Water Two-Phase Flow

Cejing jishu
The capacitance method is widely used to measure the water content of oil-water two-phase flow, whether it is the surface oil-water measurement or the stratification test of the production profile in the well.

Holdup of dispersed phase in a mixer-settler extraction column.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1990
Holdups in a stirred liquid-liquid dispersion were measured in a single-stage mixer-settler column equipped with a lifter turbine impeller. There was a large difference in dispersed phase holdup between the local positions above and below the impeller.

The effect of liquid phase properties on gas holdup in bubble column reactors

, 1987
The effect of liquid phase properties on gas holdup in bubble column reactors was investigated within a large set of gas-liquid systems. Air was used as a gaseous phase in all experiments, liquid phases included distilled water and aqueous solutions of ...
