Respected forum Members,
I am trying to simulate a separation column in ChemCad,
I have taken the exact specs given in the literature and used in the ChemCad simulations. But the simulation does not provide any results in the outlet stream (all zeros) or any warning.
ChemCad file attached, https://filebin.net/g08tsn89d87vjtco
Any input is appreciated. 
 
Column Specs
Property Package Ideal (Raults law)

Hi,

From literature , EO is very much soluble in water ( High Henry coefficient) .

Using Chemsep light , attached the results .

Flowrate unit is wrong, should be kmol/h 

 

Hope this is helping you .

Thank you so much for taking the time to do the separation on behalf of me. 

 

May I know which property package are you using in ChemSep? I have failed to do it in Aspen Plus and ChemCad.

 

Thank you.
