| Abstract: | In order to select extractive distillation solvents for benzene-cyclohexane system by the computer,we adopt molecular design method based on UNIFAC,and initial screening of solvents for extractive distillation were done with the Aspen database.The use of screening at whole tower of the primary solvent simulations were done for further screening,and we got a good solvent group:Heterocyclic compounds-NMP,Amide-DMF, Alcohol-tetraethylene glycol,triethylene glycol and so on.The results were that,the general sep... |
