• At this point you will be asked to create the rest of the files needed for the Model Solver. You should
select Continue by pressing <Enter>. This step, which serves to create a customized equation file and a
customized thermodynamic data file, specific to your chemistry, takes no more than a very few minutes
to complete in most cases. When the Generate step is complete you will be prompted to "Press any key
to continue". Press any key to continue.
You will receive a confirming prompt. Simply press <Enter> to continue. When the original screen which
allowed you to begin Chemistry Model is refreshed, you have completed preparing the Chemistry Model
and you are now free to run any number of process simulations utilizing this chemistry or any subset
thereof.
We are now ready to proceed with the next step on the tour.
Preparing to Build the Process ...
• We are ready to define the individual unit operations which make up the process shown in Figure 2-1.
First, highlight the Process Build line on the current screen and then press <Enter>. You will now see a
series of unit operations (called blocks) groupings, each containing several ESP Process Blocks. The first
block we are interested in is Conventional Blocks. This selection should already be highlighted so simply
press <Enter> to continue. We will now see several icons for individual blocks that are available. The
Mix Block should be highlighted, so just press <Enter> to access the facilities for describing the Mix
Block.
• The Mix Block schematic will now appear on the screen with the cursor set at the Block Name field.
Simply type the name MIX1 and press <Enter>.
• The cursor is now at the name for the first feed stream. Simply type BASE WASTE and press <Enter>.
• You will now be prompted to fill out the description of the physical state of the first feed stream. You
want to simply enter the values shown in Figure 2-1 for this stream. First, however, you need to change
the default units to metric. This is done by pressing the Action Key and highlighting the Units facility on
the Action Bar. Once this is done, press <Enter> and a units selection window will be activated. Use the
right arrow to toggle the first field to METRIC and then press <Enter>. Metric will now be the default for
the balance of this session. Now, enter the values shown for this stream in Figure 2-1 (where dashes are
shown the corresponding fields should be left blank). When all values have been entered, press the
<End> key or <Esc> key to move along.
