Acetic acid extraction is an important operation in industrial field. This paper focuses on the modeling and simulation of the extraction tower. To simulate the column correctly, the liquid phase non-idealities were described by UNIQUAC model. The binary parameters were regressed from liquid-liquid equilibria experiment data. The model of the column was built by considering mass balance, equilibrium balance and summation equations. Newton-Raphson method was used to solve the non-linear equations. Model results agreed well with the industrial data
Keywords:Acetic acid, extraction, simulation, terephthalic acid
