What property equations should be used in the ASPEN method for dibutylene extraction with DMF? Is Wilson suitable?

I am also doing simulations for DMF extraction, mainly using UNIFAC.

First, determine: activity coefficient method → non-electrolyte → operating pressure low at 10 bar → no binary interaction → non-liquid-liquid phase. Therefore, the available methods are: UNIFAC, UNIFLBY, UNIF-DMD, while Wilson is generally used for the \"activity coefficient method → non-electrolytes → operating pressure less than 10 bar → presence of binary interactions → gas-liquid phase equilibrium\"”

Could you send me your styrene extraction simulation source file? I’d like to learn from it; as a beginner, I’m really stuck
