Packed upflow bubble columns. Packed upflow bubble columns are used in the chemical industry, in biotechnology, and in waste-water purification. They are usually operated in the co-current mode and have various advantages, but also disadvantages, compared with empty bubble columns. This survey reports the current state-of-the-art in fluid dynamics (flow states, pressure drop, holdup and dispersion, bubble size and bubble rise velocity, interfacial area), mass and heat transfer (mass transfer coefficients at the gas/liquid and liquid/solids interface, heat transfer coefficients for fluid/solids and fluid/wall interfaces, effective thermal conductivity of the bulk solids through which flow occurs), flow models (continuum models, stage models, zone models), and other aspects of this type of multiphase reactor; gaps in our knowledge are also indicated.
