Internal heat integrated technology was developed to improve the thermodynamic efficiency of distillation columns to save energy and increase profit. A novel internal heat integrated distillation column, middle vapor recompression distillation column (MVRC), was proposed and simultaneously investigated in comparison to the vapor recompression distillation column (VRC) and the heat integrated distillation column (HIDiC). Temperature difference from top to bottom (ΔT_CDiC), operating pressure (P_CDiC), and feed state in the conventional distillation columns (CDiC) were considered when studying the feasibility and flexibility of these three columns. Moreover, the economic evaluation was completed by calculating the total annual cost (TAC) for the selected economic model. The results show that the MVRC is a formidable internal heat integrated distillation column configuration with a wide range of applications due to its operational flexibility.

新型中蒸汽减压蒸馏塔的可行性评估

开发内部热集成技术以提高蒸馏塔的热力学效率，以节省能源并增加利润。提出了一种新型的内部热集成蒸馏塔，中间蒸汽再压缩蒸馏塔（MVRC），并与蒸汽再压缩蒸馏塔（VRC）和热集成蒸馏塔（HIDiC）同时进行了研究。上下温度差（ΔT _CDiC），工作压力（P _CDiC），并在研究这三个塔的可行性和灵活性时考虑了常规蒸馏塔（CDiC）的进料状态。此外，通过计算所选经济模型的年度总成本（TAC），完成了经济评估。结果表明，MVRC具有强大的操作灵活性，是一种强大的内部热集成蒸馏塔配置，具有广泛的应用范围。
