In this article, experimental and numerical investigations are performed to study a liquid thermal diffusion column for the separation of toluene from n-heptane mixture. This research has tried to determine the main significant parameters and their effects on the performance of the process. In experimental examinations, the influence of the main parameters such as feed flow rate and temperature gradient on the performance of the thermal diffusion column efficiency is studied. In addition, computational fluid dynamics is used to simulate the separation process in this review. The numerical results showed that the predicted data were in good agreement with experiment data, and the average error between experimental and simulation data was around 20%. It was found that the separation factor increased by 129 % when the feed rate is changed from 4 to 0.8 ml/min at Ѳ=0.5 and ΔT=40 K.
