【 摘 要 】

References(17)Cited-By(19)In this paper, an ideal heat integrated distillation column (HIDiC), which has neither a reboiler nor condenser, is considered. A dynamic model, capable of doing both static and dynamic simulations of the ideal HIDiC is derived. Based on this model, the system properties and control feasibility are studied. It is found that the ideal HIDiC could be regulated quite well with manipulation of feed thermal condition and the pressure of either rectifying or stripping section. The efficient way to control its top and bottom product qualities is to use composition inferential systems to realize direct composition control.
