I wanna do a classic extractive distillation with water, ethanol and benzene.
So I send water and ethanol as feed in column 1, the top product goes in column 2 and I add a second feed with benzene.
Now I expect water, ethanol and benzene to be the top product and ethanol bottom product, but I get 99% benzene as bottom product.
Can anyone help?
Can you elaborate more regarding your problem? Which column(shortcut, rigorous or Chemsep) are you using and What are the column specifications you are giving?
