The influences of pressure distribution on an ideal heat-integrated distillation column (HIDiC)

In this paper, the static and dynamic influences of pressure distribution are examined on an ideal heat-integrated distillation column. In the aspect of process design, pressure distribution is found to have an effect upon the thermodynamic efficiency and it appears beneficial to explore an optimum pressure distribution during process development. From the viewpoint of process operation, the dynamics of pressure distribution may give rise to a severe deterioration on process controllability. Therefore, it should be taken into account in control system design for an ideal HIDiC.
