Abstract (en)
In this paper, the influence of liquid and gas flow rates, vibration intensity, and solid phase volume fraction on the axial mixing of the liquid phase in axial direction of reciprocating plate columns with different geometry (columns RPC1 and RPC2: inner column diameter 2.54 and 9.2 cm, working height 173 and 86 cm, number of perforated plates 65 and 15, and fractional free area 51 and 45.4 %, respectively) was investigated. The tap water flowing down (superficial velocity: up to 0.9 cm/s), air (superficial velocity to 1.5 cm/s) and the polypropylene spheres (diameter 8.3 mm, density 890 kg/m3, ratio up to 8.43 %) were used as the liquid, gas and solid phase, respectively.
To study the axial dispersion (axial mixing) the resident-time distribution function was
used, which was determined by the pulse input method with sorbic acid used as a tracer
(tracer concentration was measured at the column outlet).

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
