Maintaining Planning Tools. Maintain refinery margins by updating refinery planning models with streamlined workflows using a process simulation solution calibrated to plant data. Monitoring Heat Exchanger Fouling. Sulfur Recovery Unit Optimization. Engineering Procurement and Construction. Minimize estimating risk and develop bids faster through the improved consistency and accuracy of an integrated, model-based estimating system.

Cut CAPEX and prevent issues by selecting optimal trays and packings with interactive plots built using correlations and process simulation data. Dynamic Studies. Hone your understanding of operational changes through dynamic insights with trusted accuracy and built-in templates to get started. FEED Execution. Reduce FEED package preparation time and decrease rework by allowing engineering design changes to propagate consistently through interconnected FEED tools. Integration with Detailed Engineering.

Deliver bids with optimized designs faster, with less rework and errors through an integrated model based estimating tool from concept design t Operations Decision Support. Then in the right pane on the 'selection' tab, click the 'Review' button at the bottom right. These should match the values from the course textbooks. Click on 'Next'. Stream specifications will appear. You must choose the stream composition, flow rate, and state for feed streams. The state is specified by pressure, temperature, and vapor fraction.

For this example, for the feed stream 1 choose a pressure of 1 atm and a temperature of 25 o C. If you enter feed composition as mole fractions, you also have to specify the total flow rate. Click on Next. The block RadFrac setup will appear. For this rigorous simulation, you must specify the column configuration. Enter the number of stages as 33 and specify total condenser. Note that in the newer versions of Aspen, a menu item for 'Block Options' will appear the the left browser panel.

Selecting that will bring up a form where the thermodynamic property model can be specified to override the default. Hit 'Next' and the 'Stream' page appears. Locate the feed stream 1 on stage Hit 'Next' to get to the 'Pressure' page. By leaving the other sections of the pressure page alone, pressure drop through the column will be ignored in this calculation. All required information should now be complete.

Click 'Next'. You should now get a message that all required information has been entered. If you don't, complete the required form or look at the menu on the left for any red semicircles. To run the simulation, click OK on the message, or you can run the simulation on Run in the 'Run' pulldown menu. To view results, click on the blue folder in the toolbar.

Choose 'Stream' to view stream properties, or 'Block' to view column properties. In 'Streams', you can look at the streams you wish and place a streams table on your PFD by clicking the 'Stream Table' button. Note: pasted stream tables are NOT updated if you modify the simulation and rerun. In a complex simulation, it is sometime more convenient to work with the PFD to find results.

Right-click on a block or stream for a short-cut menu to results. You can bring up compiled reports by going to the 'View' menu and clicking on the desired information. The information in the reports is controlled somewhat by the report options introduced in Section 4. You can study the behavior of the column by looking at the column profiles as shown below from the 'Results' data browser.

An example table is shown below. For compositions, choose the composition tool, specify liquid mole fractions. The analysis below shows that there may be more stripping stages than necessary for the given column 33 stages, flowrates, reflux and boilup. Naturally, compositions at the top of the column are limited by the azeotrope. You can print the process flowchart and include the stream table if you have pasted it onto the PDF.

Then select 'Print'. To print 'Input Summary', 'History', or results 'Report' , go to the 'View' menu and select your choice. Save the information as a Notepad.

The default reports have more information than you typically need. Avoid printing reports without reviewing them or pasting them in a Word document or you will use up print quota quickly! As you work with Aspen plus and Aspen Properties, saving files in the 'backup' format will assure that they can be opened in the next version of Aspen.

Currently it is not possible to open 'standard' files when upgrading Aspen. The backup format ends with an 'bkp' as the last part of the file extension. You will want to modify your process parameters to run the case again. After modifying, you can click the 'Next' button, or the 'Run' button.

Aspen will 'reuse' the last state to start the next simulation. When a case crashes, this is usually not desirable. Be sure to explore the phase behavior of the systems in your design.
