✦ Synopsis

The analysts of the mass transfer III a bundle of parallel capdlartes wtth vartous dtameters shows that wtthm a certam range the achievable changes of the concentration are almost Independent of the mass flow rate, the dtffustvtty and the magnitude of the interface Thrs result contradicts those, which follow from the assumption that a heterogeneous system can be consrdered to be equivalent to a quasi homogeneous one, mtroducmg e g an average hydrauhc drameter and other average values The latter procedure, however, IS apphed for the predrctron of mass transfer rates m mass transfer equipment as, e g in fixed beds, flmdtzed beds and on bubble trays The given analysts mdtcates that this procedure may induce considerable errors as to mass transfer eqmpment design 1 lNTRODUCTION
