The operation and control of a dividing-wall column
a fully thermally coupled distillation column configuration
is more complex than the traditional column because of its coupling nature. However it exhibits more flexibility due to the more degree of freedom. In the present paper the operation flexibilities of dividing-wall columns for separating the mixture of n-pentane
n-hexane and n-heptane with different compositions are investigated by using rigorous simulation. And the effect of the feed composition on the operation flexibilities are also investigated.
