摘要
Abstract
The second extractive distillation unit of C5 hydrocarbons was introduced,the vapor-liquid equilibrium of dimethylformamide-C5 was predicted by UNIFAC group contribution method,and the binary interaction coefficient in Wilson equation was corrected so as to establish a thermodynamic model based on Wilson equation applicable for simulation of extractive distillation for C5 hydrocarbons with dimethylformamide.With the software Aspen Plus,the simulation analysis of the 2nd extractive distillation column was performed,the influence of such main process parameters like solvent/feed ratio (mass ratio),reflux ratio and feed position on the separation effect and thermal load of column was investigated,and the proper process operating conditions were determined,thus providing the basis for energy saving and consumption reduction.关键词
