Gas Holdup in Gas−Liquid Stirred Tanks

Industrial & Engineering Chemistry Research, 2010
A single-point optical probe is developed that can accurately obtain local gas holdup in a gas-liquid stirred tank across a wide range of operating pressures, temperatures, and fluids. It is found that the probe orientation to the flow in a stirred tank can cause underestimations in gas holdup if only a single probe orientation is used.

Gas holdup in pneumatic reactors

The Chemical Engineering Journal, 1988
Abstract The gas holdup expressions of the form eG = aU sg b often observed to be applicable in bubble columns and airlift reactors, are shown ...

Liquid Holdup in Wet-Gas Pipelines

SPE Production Engineering, 1987
Summary An experimental study of two-phase flow was conducted to investigate liquid holdup in wet-gas pipelines. The liquid-holdup data were obtained by passing spheres through a 1,333-ft [406.3-m] -long, 3.068-in. [77.93-mm] -ID horizontal pipe and measuring the liquid volumes removed. Three different two-phase mixtures were used.

Gas Holdup in a Fiber Suspension

The Canadian Journal of Chemical Engineering, 2003
AbstractThis paper investigates the effects of fiber mass fraction and length on gas holdup and flow regime transition. The experiments are performed using three different Rayon fiber lengths (3, 6, and 12 mm) over a range of superficial gas velocities (Ug ⩽ 18 cm/s) and a range of fiber mass fractions (0 ⩽ C ⩽ 1.8%) in a 15.24 cm diameter bubble ...

Gas holdup and energy dissipation in liquid‐gas ejectors

Journal of Chemical Technology & Biotechnology, 2008
AbstractBACKGROUND: Ejectors have excellent mass transfer characteristics with energy efficiency and can be used in place of conventional countercurrent systems, namely, packed bed contactors as well as venturi scrubbers, cyclones and airlift pumps. Although a number of papers have been published in the recent past, none of them provides a theoretical ...

Frother persistence: A measure using gas holdup

Minerals Engineering, 2009
Persistence here refers to the how long a frother remains effective in producing small bubbles, one of its prime functions in flotation. One way to evaluate is to track gas holdup over time while air is sparged into a column: if frother is depleted bubble size will start to increase consequently increasing bubble rise velocity and hence decreasing gas ...

Gas holdup and single bubble velocity profile

International Journal of Mineral Processing, 2011
Abstract Single bubble velocity profile (velocity vs. distance) has been measured for a 1.45 mm diameter bubble to try to explain reported differences in gas holdup in two systems: F150 vs. 1-pentanol, and MIBC vs. NaCl. It was found that in F150 the bubble slowed rapidly to reach the terminal velocity stage of the profile while in 1-pentanol the ...
