EN The paper presents the results of experimental studies on one- and two-phase flow in packed columns. In the study, natural materials (LECA, pumice stone, cones, coconut fiber, wood chips, walnuts, shells), waste materials (plastic nuts, bricks, tiles), copper springs, and plastic acorns were used as packing. The relationship between the flow resistance coefficient and the Reynolds number is described. In the model, the relationship between the pressure drop on the sprayed packing and the pressure drop on the dry packing is presented. The characteristic values for the studied materials were obtained. The study constitutes the basis for further studies of packings of various origins in order to determine the influence of variable geometrical dimensions.
