Electrical capacitance tomography has been used to image a bubble column. Sets of linear back projection tomographs are then analysed to yield gas hold-up values and to determine flow regime in a traditional manner. Further analysis is performed producing a statistic (Heterogeneity Index for Tomograms) that is independent of the average hold-up. This is used to provide an alternative and superior means to determine flow regime.
