A few days ago we showed you how to create tabs in your PFD. Also known as flowsheets. Today we’ll show to you how you can improve the look of your simulation using flowsheets in PRO/II 9.2.
Let’s start with a very bad looking simulation. Would you have a PFD with an entire plant on one single piece of paper? Probably not. No need to do it in PRO/II either.
That’s what you get if you import C:\Users\UserID\Documents\SimSci\PROII92\Applib\Casebook_VCM_Plant.inp

If you want to follow along, copy the file first so you do not destroy the good Casebook_VCM_Plant - Copy.prz that comes with the package.
Let’s divide this simulation into two reaction sections and two purification sections plus a quench.
COL3 and COL4 belong on one purification section.
Getting a rectangle around them and collapse like we showed the other day will also take a lot of other unit operations on the flowsheet. Instead you can first create the flowsheet by dropping a “BLOCK diagram” from the palette, give it a name (COL_3_4), and open it. It will be blank.
Move to the main flowsheet now, and select FLS7, while pressing shift key select COL3, and COL4. A rectangle will form , but only COL3 and COL4 will be selected. Right Mouse click and select Cut, or do a Ctrl-X. Now move to the flowsheet previously created and paste (right mouse paste or Ctrl-v).
Return to main flowsheet. Create a second block, name it COL_1_2. Open it. Return to main flowsheet. Select MIX5, FLS3, MIX6, COL1, MIX7 and COL2, cut and paste them inside COL_1_2. You may want to rearrange a little.
Return to main flowsheet. Create third block, name it DirectRx. Open it. Return to main flowsheet. Select MIX1, SPL1, RX1, RX2, MIX2, FLS1, STC2. Cut/paste onto DirectRx. Rearrange a bit. Oops, we forgot to add CAL2, let’s go back to main flowsheet, cut CAL2 and paste it into DirectRx.
Return to main flowsheet. Create a new block, name it OXYRX. Select MIX3, SPL2, RX3, RX4, MIX4 STC3, and FLS2. Curt and paste into OXYRX.
Now may be you can select the rest of the units using a rectangle and cut all of them at once. For that you create a new Block, rename the block Quench. Select a rectangle covering all the rest of the unit operations, and cut it. Move into Flowsheet Quench and paste. Now a little arrangement.
Return to main flowsheet. Window/Tile horizontally and zoom 100 each small view. You can enlarge either one individually and rezoom to 100.
Not too bad, and it is much easier to see and use! Run and see it working.
You can play this video to see the steps. It only takes 7 minutes to do the entire process!
About PRO/II: PRO/II is the major product in the Process Engineering Suite (PES). This process simulation software optimizes plant performance by improving process design, operational analysis, and performing engineering studies. It is designed to perform rigorous heat and material balance calculations for a wide range of chemical processes. PRO/II allows users to evaluate the use of heat integration with case studies, rigorously evaluate process improvements with the help of a process flow diagram (PFD), or model crude distillation units. PRO/II offers a wide variety of thermodynamic models to virtually every industry and is incredibly cost effective, decreasing both capital and operating costs.
