In the proposed method, the energy and size parameters in studied Equation of State (EoS) have been obtained using the Wong – Sandler (WS) mixing rule combined with the NRTL and Wilson Gibbs equations. The NRTL and Wilson parameters for aqueous solutions of alkanolamine mixtures have been correlated using measured viscosity data at atmospheric pressure and different temperatures. The overall average deviation between the experimental and calculated viscosities of studied aqueous solutions of alkanolamine mixtures using Wilson model is 0.92%.      UR - https://ijcce.ac.ir/article_5863.html L1 - https://ijcce.ac.ir/article_5863_d4cf70090b6f82b504893d1e66d9f13a.pdf ER -
