UDC 66.048.3

A mathematical model of the process of rectification of 
a multicomponent mixture on a bubble plate is presented. The transfer 
processes in the two-phase gas-liquid flow are described using 
a two-liquid model with account for the distinctive features of the 
phase interaction on the plate. The results of calculations according 
to the Young model are compared to the experimental data on the rectification 
of an N-hexane-ethanol-methylcyclopentane-benzene mixture 
on a sieve plate 0.302 m in diameter.
