Gas holdup and axial dispersion in gas-liquid concurrent bubble column.
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1987 An experimental investigation was carried out to determine the effect of liquid flow on gas holdup and axial dispersion coefficient in a gas-liquid concurrent bubble column 20 cm in diameter, in the ranges of gas and liquid superficial velocities of 0.21-0.87 and 0-1.16ms-1, respectively. Theoretical expressions of the turbulent recirculation flow were

Interfacial Area and Gas Holdup in an Agitated Gas-Liquid Reactor under Pressure
Industrial & Engineering Chemistry Research, 1995 The chemical method has been used to measure gas-liquid interfacial areas in a mechanically agitated gas-liquid reactor at pressures up to 6.6 MPa. The 4.7 L vessel had an inner diameter of 15.6 cm with a dispersion height set equal to the diameter. The influence of pressure, agitation rate, gas velocity, and liquid viscosity on the interfacial areas ...

Gas Holdup in Highly Viscous Liquids in Gas-Liquid Spouted Beds.
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1995 Gas holdup in highly viscous fluid in two phase spouted bed operated continuously with respect to the gas flow and batchwise with respect to the liquid was investigated using bed expansion technique. Experiments were carried out in three cylindrical spouted beds having diameters of 74 mm, 114 mm and 144 mm and height of 1000 mm under the conditions of ...
