swings in extraction columns, and thus they operate virtually isothermally. There are
no condensers or reboilers, and therefore the number of degrees of freedom is equal
to the number of available equations, and no operating specifications are required. The
Extract block is a rating or simulation model, and its use requires the specification of
feed rates, states, and locations as well as the number of equilibrium stages.
When preparing an extraction column simulation, a review of the available data
in Aspen Plus's databases is imperative. Figure 11.25 shows the Uniquac parameters
