Recently, self-heat recuperation technology has been developed. In this technology, whole process heat is recirculated in the process without heat addition, leading to the drastic energy saving for the process. Although the process based on this technology can achieve drastic energy saving at steady state, the dynamics of the process have not been investigated. Therefore, operators of the process have to manually switch the conventional operation mode to the operation mode by self-heat recuperation at reaching steady-state. Two stream lines for each operation mode are required and increase the capital cost. Thus, in this paper, the dynamic characteristics of the self-heat recuperative process for distillation have been investigated to design operation systems such as controllers for further energy saving and stability of this process during operation.
