Process simulation of separating butadiene with DMF extractive distillation
1,3-Butadiene production process with DMF extractive distillation is simulated by ASPEN PLUS process simulation software.The results of simulation are consequently compared with the plant data,which shows good accordance with each other.Based on the results of simulation,the influence on solvent ratios,reflux ratios and DMF temperature on separation is discussed.The proper operating conditions are given.
