Go to the File menu, select New, followed by Case, or 2. Your first task is to set your Session Preferences. The conditions and composition of the column feed stream, as well as the operating pressure, define the resulting converged solution. Hint, hint, wink, wink, nudge, nudge. You may change this temperature to see how it affects the Heat-duty.
On the Variables Page, you should see three variables already defined. Select Reactor from the Object List. Defining the Simulation Basis 1. The only unit operation contained in the Absorber is the Tray Section, and the only streams are the overhead vapor and bottom liquid products. Note that only blue colored fonts are the values that you specified. Workbook will be shown as in Figure 9.
Ensure that the Use Modal Property Views checkbox is unchecked. From the list of fluid sfudy, select the desired thermodynamic package. The only unit operation contained in the Absorber is the Tray Section, and the only streams are the overhead vapor and bottom liquid products. For pump to have enough information, it only requires outlet pressure assuming that the inlet stream is fully specified.
In addition, the book can be a supplement or a secondary book in courses where HYSYS is used, but the instructor does not have hysjs to cover it extensively.
Run the simulation and see how the column dimension and exit concentration of CO2 have changed. In the Variables page, click Add…, and Figure will be shown. An Introduction to Chemical Engineering Simulations vase intended for students who are using HYSYS for the first time and have little or no experience in computer simulation.
Note that a total condenser does not count as a stage. You will be using a hypothetical component to model the component in the gas mixture heavier than hexane.
Add a Valve operation and provide the following information: Add a distillation column and provide the following information: Click Next, and then enter the following information as shown in Figure This will automatically connect the proper reactions to this reactor. Defining the Simulation Basis 1. Click the Unknowns Only button. Note that only blue colored fonts are the values that you specified.
Once the analysis finished, click Results to view the result. Once the desired model has been located, select it by clicking on it once no need to double click. It is assumed that the software is installed on the computer, and the user has basic knowledge of operating the computer.
Therefore, you need to create this component using Hypothetical.
In the Adiabatic Wtudy box on the parameters page, enter Click on the Add Utility button. Figure What is the flowrate of the overhead product, DC1 Ovhd? At this point, either the outlet stream temperature or the cooling duty can be specified. Obtain the mass flowrate of the cold stream. At the end of this chapter, the user will determine the expander outlet temperature when given hyss efficiency or vice versa. Click on the Reactions tab in the Simulation Basis Manager view.
You can also examine the actual conversion, the base component, the equilibrium constant, and the reaction extent for each reaction in the selected reaction set.
Case Studies Example
Depending on the information specified, the Pump calculates either an unknown pressure, temperature or pump efficiency. Double click molar flow rateand fill in the composition and close. What is the new temperature of this stream?
Switch to the Case Studies tab. Obviously, there will be upper limit of Pre-Heat temperature no matter how good your heat exchanger is. The Expander provides a great deal of flexibility with respect to what you can specify and what it then calculates.
At the end of this chapter, the user will determine the compressor outlet temperature when given compressor efficiency or vice versa.
The pump increases the pressure of the liquid.
