A new invasive sensing probe for the measurement of local phase holdups in two-and three-phase reactors is described. The local gas and solids holdups in a bubble column with a volume of V = 2 m 3 at varying operating conditions (gas velocity, sparger design, solids content and density) are measured
Experiments of pressure effects on gas holdup and bubble size in slurry bubble columns at 5.6 MPa and at gas ยฎelocities up to 45 cmrs indicate that the gas holdup increases with an increase in pressure, especially at high slurry concentration. At ambient pressure, a higher solids concentration signi
