摘要: Nowadays,extractive distillation is the main technique to produce 1,3-butadiene.This study simulated the 1,3-butadiene production process with DMF extractive distillation by Aspen Plus.The solvent ratio is the most important parameter to the extractive distillation process.The article has given out the proper solvent ratios,reflux ratios,distillate ratios,and bottom product ratios of the columns.It also discusses the thermal loads of several columns.The results of simulation are consequently compared with the plant data,which shows good accordance with each other.
