| Abstract: | Nonequilibrium thermodynamic analysis for extractive distillation process was made. The separation criteria for implementing extractive distillation process were proposed, which will be theoretically helpful to the design of extractive distillation process. The mathematical equation of entropy generation, which can be used for energy-saving analysis, was deduced and verified to be reliable. The results presented in this work can only be applied to the tray distillation column and are in the linear range of nonequilibrium thermodynamics. Moreover, it is valuable for other special distillations with separating agent about why the process can be carried out. |
