Creating a Simulation Model This example describes how to construct a polymer simulation model.It provides an overview of Aspen Polymers Plus features.The steps covered include:Creating a New Run Creating the Process Flowsheet Specifying Setup and Global Options Specifying Components Characterizing Polymers Specifying Physical Properties Specifying Feed Streams Specifying Kinetics Defining the Unit Operation Block Running the Simulation Examining Simulation Results Plotting Distributions Creating Live Distribution Plots Pasting and Linking Between Aspen Polymers Plus and Excel Saving the Run and Exiting The process in this example uses two CSTR reactors and a mixer.The free-radical kinetics occur in the reactors.Creating a New Run To construct the simulation model you need to start Aspen Polymers Plus.To start Aspen Polymers Plus:1 Start Aspen Plus from the Start Menu or by double clicking the Aspen Plus icon on your desktop.The Aspen Plus Startup dialog box appears.6 A1 Creating a Simulation Model 2 On the Aspen Plus Startup dialog box,click the Template option.Click OK.The New dialog box appears.You use this dialog box to specify the simulation template and Run Type for the new run.Aspen Plus uses the Simulation Template you choose to automatically set various defaults appropriate to your application.3 For this example,click Polymers with Metric Units for your template.The default Run type,Flowsheet,is appropriate.Click OK.The Aspen Plus main window is now active.Creating the Process Flowsheet In a flowsheet you can:Place(or delete)blocks Place(or delete)streams Rename blocks and streams The process flowsheet for this example is shown here.Placing Blocks and Streams Follow these instructions to:Place unit operation blocks Place streams and connect blocks To place unit operation blocks:1 In the Model Library,click the Reactors tab,then the RCSTR icon.2 Move the mouse to the Process Flowsheet window,then click to place block B1.3 In the Process Flowsheet window,click to place the second RCSTR block,B2.4 In the Model Library,click the Mixers/Splitters tab,then the Mixer icon.A1 Creating a Simulation Model 7 If you want to select different Mixer model icons,click the down-arrow on the icon.To place streams:1 Click the Material STREAMS icon on the left corner of the Model Library and move the mouse to the Process Flowsheet window.Red and blue arrows appear on the unit operation blocks.These arrows indicate the location of the required(red)and optional(blue)stream connection ports.2 Place the“+”cursor on the red feed arrow of B1 and click to make the connection.Move the mouse away from the block and click again to place stream 1(FEEDA).3 Place the“+”cursor on the red product arrow of B1 and click to make the connection.Move the mouse to the red feed arrow of B3(M)and click again to connect the two blocks.Refer to the process flowsheet for the location of these streams.4 Repeat these steps to create a feed stream for B2,connect B2 and B3(M),and create a product stream for B3(M).5 After placing all streams,turn off the insert mode by clicking the Select Mode button in the upper left corner of the Model Library.Renaming Blocks and Streams To rename blocks and streams:1 Click the block to be renamed,such as B3,and click the right mouse button to display the menu.2 Click Rename Block.3 Enter the Block ID as“M”and click OK.4 Click the stream to be renamed,such as 1,and click the right mouse button to display the menu.5 Click Rename Stream.6 Enter the Stream ID as“FEEDA”and click OK.7 Repeat these steps to rename the other streams.You are now ready to enter input data for your simulation.Specifying Setup and Global Options To enter process and model specifications into Aspen Polymers Plus,you can use the Next button or the Data Browser Menu Tree.In this example,you enter data using the Menu Tree.Use the Setup folder to:Enter a simulation title Define unit-sets 8 A1 Creating a Simulation Model Review and specify global options set by the simulation template you selected Entering a Simulation Title To enter a title:1 From the Data menu,click Setup.The Setup Specifications-Data Browser appears.2 On the Global sheet,type the title of your simulation run as:Creating an Aspen Polymers Plus Simulation Model Defining Unit-Sets This example requires a user defined unit-set for input data and output results.To define a unit-set:1 From the Setup folder in the Menu Tree,double-click the Units-Sets sub-folder.2 Click New to create a new set.3 Enter an ID(for example,SET1)and click OK.A dialog box appears requesting approval to make SET1 the global unit set,click Yes.4 Confirm that SI is entered in the Copy from field.If it is not selected,select SI from the pulldown list.This means the simulation will use SI units as the basis for your new unit set.5 Set the following options:o Mass Flow=kg/hr o Mole Flow=kmol/hr o Temperature=C o Pressure=atm Entering a Simulation Description A Description sheet is available to enter a more detailed description of the simulation.To enter the description for this example:1 From the Setup folder in the Menu Tree,click the Specifications form.2 Click the Description tab.You can either retain or delete the default information displayed,but type the following description:This example describes how to put together a polymer simulation model.A1 Creating a Simulation Model 9 Defining Report Options Since you chose the Polymers with Metric Units simulation template when you started this example,Aspen Plus has set defaults for calculating and reporting stream properties:No mole flow Mass flow To enter a user defined stream report format:1 From the Setup folder in the Menu Tree,click the Report Options form.2 Click the Stream tab.3 In addition to the default options,click Mole for the Flow basis frame and Mass for the Fraction basis frame.Specifying Other Simulation Options To enter other simulation options for this example:1 From the Setup folder in the Menu Tree,click the Simulation Options form.2 Click the Limits tab.3 Enter 1000 in the Simulation time limit in CPU seconds field.4 Click the System tab,and click the Print Fortran tracebacks when a Fortran error occurs option.Specifying Components You use Components forms to select chemical components for your simulation and specify component types(for example,conventional,solid,assay,blend,polymer,segment,oligomer,and pseudocomponent).To select components:1 From the Data menu,click Components.2 On the Selection sheet,enter the components as shown:10 A1 Creating a Simulation Model Characterizing Polymers You must enter additional characterization information for segments,polymers,oligomers and site-based species.You must also define the type of segments present.Segments can be repeat units,end groups,or branch points attached to three or four branches.To define the segments:1 From the Components folder in the Menu Tree,double-click the Polymers sub-folder.2 From the Polymers sub-folder,click the Characterization form.3 On the Segments sheet,from the Type pulldown list,click REPEAT for segments STYSEG and ACNSEG.For each polymer you must define the component attributes to be tracked.All components specified as type Polymer in the Specifying Components section require component attributes.To specify component attributes for the polymers:1 Click the Polymers tab.2 Verify SAN appears in the Polymer ID pulldown list,or select it if it does not appear.3 In the Built-in attribute group field,click Free-radical selection from the pulldown list.The attribute summary table,Attribute list,is automatically filled in.You can click the cells in the attribute list table or clic
