The results of the analysis of the mass transfer characteristics of a reciprocating plate column (RPC) of the Karr type in the case of two-phase (gas-liquid) and three-phase systems (gas-liquid-solid) are presented. The volumetric mass transfer coefficient in the liquid phase (kLa) was analysed and the obtained results indicated that kLa depends on the vibration intensity, the superficial gas velocity and in the case of three-phase system, on the content of the solid phase present in the RPC. An empirical correlation was derived indicating that kLa does not depend on the column diameter and that for its calculation only the average power consumption in the column and the superficial gas velocity must be known.
