Based on the Bhatnagar-Gross-Krook distillation for two components in the presence equation, a new scheme of wiped-film molecular of inert gas is developed. The equations in the scheme are solved numerically by the method of finite difference and iteration. The new scheme is used to simulate the molecular distillation of dibutyl phthalate and dibutyl sebacate （ DBP-DBS ） mixture. The effects of the inert gas pressure, the distance between the evaporation surface and condensation surface, the rotation rate of blade, and the number of blades on the distillation rate and separation factor are discussed. 相似文献

Simulation of Vapor Flows Between Two Closed Surfaces of Evaporation and Condensation at High Vacuum
The steady multi-component vapor flows between two closed surfaces of evaporation and condensation are investigated numerically by the nonlinear Bhatnagar-Gross-Krook equation.The mathematical model will make it possible to determine the profiles of the process variables between two surfaces of evaporation and condensation if the conditions of evaporation and condensation surfaces are taken into consideration.It is used to simulate the vapor behaviors of the pure dibutylphthalate and the ethylhexyl phthalate-ethylhexyl sebacate mixture.The effects of the liquid composition of the evaporaton surface,the evaporation temperature ,the condensation temperature and the distance between evaporation and condensation surfaces on the evaporation efficiency and separation factor are discussed. 相似文献
