Simulation basis

The Simulation Basis Manager is property view that allows you to create and manipulate multiple fluid packages or component lists in the simulation. 

Select File/New/Case or press Crtl+N or click on the New Case to start a new case. In HYSYS, your simulation is referred to as a case . This will open up the Simulation Basis Manager which is where all of the components and their properties can be specified. 

The first step in establishing the simulation basis is to set the chemical components which will be present in your simulation. 

To add components to the simulation, click on the Add button in the Simulation Basis Manager. 

At the bottom of the components page, you can give your component list a name. Once this is complete, simply close the window by clicking the red X at the upper right hand comer of the component list view, which will return you to the simulation basis manager. 

From the simulation basis manager (Figure 1-2), select the Fluid Pkgs tab. 

For oil, gas and petrochemical applications, the Peng-Robinson EOS (PR) is generally the recommended property package. For more details, please refer Aspen HYSYS Simulation Basis Manual. 

When the basis of the simulation has to be changed, the Simulation Basis Manager needs to be re-entered. Simply click on the icon on the top toolbar to re-enter it. 

Every hypo you create is part of a Hypo Group. By default, this hypo is placed in HypoGroupl. You can add additional groups and move hypo components between groups. This is done on the Hypotheticals tab of the Simulation Basis Manager. 

Click on the Reactions tab in the Simulation Basis Manager view. Note that all of the components are shown in the Rxn Components list. 

Click the Enter Basis Environment button to view the Simulation Basis Manager. 

Simulation Basis Manager will pop up. Click Add. Fluid Package window will be opened. Choose Peng Robinson as Base Property Package. 

Click Enter Simulation Environment at the bottom of Simulation Basis Manager. Click Heater in the Object Palette and click it on Process Flow Diagram (PFD). Click General Reactor, three different reactors will pop up, click conversion reactor and click it on PFD. Do the same for the Cooler and Separator.
