| Abstract: | UNIQUAC phase equilibrium model was developed in simulating the process of DMF recovery in the liquid waste by using CHCl3 as the extracting agent and ASPEN PLUS was applied in calculating.By discussing the results on the process which was made by the altering some main parameters,such as the extracting stage,extracting ratio and reflux ratio,stage numbers,the feed position and so on,and optimized some technological parameters.Simultaneously,comparing with common distillation technology,the energy cost in the extracting-distillation technology can be saved by 80%. |
