摘要
Abstract
Batch extractive distillation process was chosen to separate tert—butyl alcohol —water mixture and the ethylene glycol as solvent. The effect of reflux ratio, solvent feeding speed and solvent feeding temperature was analyzed. The best operating conditions were that the reflux ratio was 2, solvent feeding speed was 5. Lg/min, the solvent feeding temperature was 90℃. Under those conditions, the mass fraction of tert —butyl alcohol could reach 98. 41%. The batch extractive distillation column was simulated by Aspen plus software, and an agreement was found between the predicted and the experimental data.关键词
