TWO-DIMENSIONAL MODEL OF TRANSFER PROCESSES ON A BUBBLE PLATE IN MULTICOMPONENT RECTIFICATIONA. G. Lapteva and V. A. Danilovb 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. aKazan State Power-Engineering University, Kazan, Russia; bKazan State Technological University, Kazan, Russia; email: firstname.lastname@example.org.
