VSI'KN I'll 'S SIMl'LATION OF DISTOIATIOM MHHKl.S 137

As Aspen Plus presents the window after clicking OK in Figure 3.39, choose General
with English Units. Then hit OK (see Figure 3.40).

FIGURE 3.40
Click OK when the Aspen Plus engine window is displayed (see Figure 3.40).
Remember that this step is specific to the installation.

Creating flowsheet
At present, we have a blank Process Flowsheet Window. So, we start to develop the
process flow diagram by adding a RadFrac column from the Model Library toolbar and
drawing the inlet and product streams by the help of Material STREAMS.
Now the process flowsheet is complete. The Status bar in the bottom right of the
screen, shown in Figure 3.41, displays a message ofRequired Input Incomplete indicating
that input data are required to enter to continue the simulation.
Configuring settings

Hitting Next knob and then clicking OK, we get the setup input form. In Figures 3.42(a)
'
and (b), the Title of the problem ( Simulation of a Multicomponent Column') followed
by the Aspen Plus accounting information (AKJANA/ll/ANY ID/FINE) are provided.
Include the additional items in Report Options/Stream sheet under Setup folder
(see Figure 3.43).
