    Estimation of Modified UNIFAC (Dortmund) Model Parameters

    Umeshmathur, I would like to ask you one question. Structual formula of 2-(Methylamino)ethanol is CH3-NHCH2-CH2-OH, in which i am sure that OH is a primary alcohol. But to check in aspen plus i selected secondary alcohol, and it worked well. So i would like to know that is this solvent contain...

    Estimation of Modified UNIFAC (Dortmund) Model Parameters

    Umeshmathur, I said when i removed one group, lets say OH (Which is not the proper way), i am getting good fit of my experimental results. Obviously such fit is wrong as i am not considering OH group because of the error. I think its a bug in the programme. I am fully agree with your...

    Estimation of Modified UNIFAC (Dortmund) Model Parameters

    Hello Folk, I would like to ask you guys one question, which is related to the solving of UNIFAC model in Aspen Plus. Actually I am trying to find the group-group interation parameters by using the experimental heat of mixing data of different amines. I would like to describe my problem by...
