The influence of the gas flow rate and vibration intensity in die presence of the solid phase (polypropylene spheres) on axial mixing of the liquid phase in a three phase (gas-liquid-solid) Karr reciprocating plate column(RPC) was investigated. Assuming that the dispersion model of liquid flow could be used for the real situation inside the column, the dispersion coefficient of the liquid phase was determined as a function of different operating parameters. For a two-phase liquid-solid RPC the following correlation was derived: D L =1.26(Af) 1 . 4 2 U L 0 . 5 1 e s 0 . 2 3 and a similar equation could be applied with ′ 30 % confidence for the calculation of axial dispersion in the case of a three-phase RPC: D L =1.39(Af) 0 . 4 7 U L 0 . 4 2 U G 0 . 0 3 e s - 0 . 2 6
