Abstract
A mathematical model of dephlegmation processes (i. e. of partial condensation with countercurrent flow of rising vapour and falling condensate) has been proposed and the results of the simulation have been compared with those of five series of experimental runs carried out with two different binary systems. The agreement between calculated and measured values of the variables (compositions, temperatures, heat transfer surface) has been found satisfactory. Moreover, the extent of the rectification obtained from the experimental runs is generally small and appears to be slightly sensitive to both the temperature and the flow rate of the coolant.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
