Effect of inert gas on molecular distillation process

On basis of the Bhatnagar-Gross-Krook equation, a new scheme for multi-component flow calculations between two closed surfaces of evaporation and condensation is developed. It is used to simulate the vapor behaviors DBP-DBS mixture system in the presence of an inert gas. The effects of evaporation temperature, condensation temperature, inert gas pressure and distance between evaporation and condensation surfaces on the separation factor are discussed.
