碩士 === 明新科技大學 === 化學工程研究所 === 96 === The reactive distillation combines the chemical reaction and separation in one column. This research uses two kinds of thermodynamics analysis methods to reflect the discussion of the reactive distillation column, The column grand composite curve （CGCC） is similar to the grand composite curve used in pinch technology, provides a convenient tool for energy analysis and process integration for distillation column. The exergy loss profile shows the irresibility and energy inefficiency within the distillation column. Synthesizing MTBE by reactive distillation from methanol and mixed butenes are studied. The performances of different configurations through changing feed location are analyzed. The results show that the exergy loss profile is consistent with the results by traditional total annual cost（TAC）analysis. The CGCC can be applied to reactive distillation column target analysis. The CGCC and exergy analysis can be easily calculculated from converged results from process simulator, and be available from some commercial flowsheet simulators. The thermodynamic analysis can be considered as one of the methods applied to evaluate the performance of reactive distillation in additional to the TAC analysis.
