aspen module

Thread Content

I have a question: the extract module in Aspen can be used to extract the product, but if one wants to achieve complete separation of the product from impurities, is it necessary to set specifications requiring that the impurity content at the top of the tower be greater than 0.99, and the product content at the bottom of the tower also be greater than 0.99? Is such a setting acceptable?

How should it be set up so that isopropanol and butanol are completely separated? Water and isopropanol contain almost no butanol, while benzene and butanol contain almost no isopropanol

Check the design specifications or sensitivity analysis parameters to see what level of separation can be achieved.

Under normal circumstances, only one purity requirement can be met

So if I want to achieve a complete separation, are there any other actions or settings needed?
