Rebolier tabs become available. When the Thermosyphon Config tab is selected, the
thermosyphon reboiler baffle configuration may be selected, as shown in Figure 11.17.
When the tab Reboiler specification is chosen, Figure 11.18 appears. This permits
various reboiler specifications to be made for either kettle or thermosyphon reboilers.
If the Reboiler Wizard button is pushed, the Reboiler Wizard display, on the right
of Figure 11.18, appears and enables details of an associated heat exchanger to be
entered, including a link to the Heatx block. Results for this simulation may be found
at Example/RadFracExample1.
The RadFrac block has an associated design specification function. In the example
above, the DSTWU solution shows a 0.95 recovery fraction of methanol; however,
the rigorous RadFrac solution shows that the recovery is 0.937. One possibility for
improving the recovery is to vary a column specification, in this case either the distillate
rate or the reflux ratio. Use of the design specification, varying the distillate rate,
