| Popis: | 99 This work is done by simulator to purify acetic acid by heterogeneous distillation at steady state.The feed compositions are Acetic acid, H2O, Methyl Acetate, and P-xylene. This work has the result of three azeotropies. One is the homogeneous azeotrope of HAc-PX, its azeotropic temperature is 92.2℃, another is the homogeneous azeotrope of H2O-MA, its azeotropic temperature is 56.66℃, and the other is heterogeneous azeotrope of PX-H2O, its azeotropic temperature is 92.29℃. Because of H2O-PX has heterogeneous azeotropic point at 92.29℃, this work were conducted with a modified NRTL model. The VLE and VLLE data were correlated by the activity coefficient models of NRTL with the consideration of the association by Hayden and O’Connell in the vapor phase. |
