Distillation of ethyl acetate and water
Thread Content
Dear experts, there is a significant discrepancy between the boiling point compositions reported in the literature and those obtained through the distillation of ethyl acetate and water: the literature values indicate a water content of around 6%, while ASPEN’s calculations give a value of around 12%. Could you help me check this? Additionally, why isn’t the quality composition at the tower top improving? Could you help identify where the problem lies?
Check the vapor-liquid equilibrium and try doing a property regression
Esters and water may separate at normal pressure and temperature; vapor-liquid-liquid equilibrium calculations should be used. The VLL method is employed to predict the azeotrope, thereby determining the heterogeneous azeotrope temperature and its composition.
