## Abstract The average large gas bubble size in slurry bubble columns is estimated using a spectral analysis method applied to measured pressure time series. A pressure time series measured in a bubble column consists of local pressure fluctuations and global pressure fluctuations. The local press

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
