In this paper, a novel design methodology based on self-heat recuperation for heat integrated distillation column (HIDiC) is proposed. In HIDiC, the condensation heat is recovered and exchanged with the vaporization heat in the column for energy saving. By following self-heat recuperation technology, the energy input and output of HIDiC are analyzed and the process heat circulates through the process by using pressure change, leading to further energy saving. The simulation result demonstrates that the energy consumption for HIDiC based on the proposed design methodology by using self-heat recuperation is drastically decreased as compared with benchmark processes which use external heat sources.
