In this article, numerical simulations are performed to investigate the performance of the thermal diffusion column for the separation of n-heptane/benzene mixture. In order to obtain the hydrodynamic and temperature and mass distribution inside thermal diffusion column, computational fluid dynamics (CFD) method is applied as a robust approach to solve the Navier-Stocks equations. Numerical simulations are conducted to study the main parameters in both stationary and time-dependent conditions. By using the separation work unit as a function of cut, the optimal cut for maximum SWU occurs within a limited range of 0.47-0.5 for feed rate between 0.5 to 4 g/min.
