Process Involving Recycle, Example 4: HYSYS prompts you to provide a name for the new Preference file, which you can later recall into any simulation case by clicking the Load Preference Set button 2. Methods The methods adopted in accomplishing this work, which was carried out to obtain the model, are outlined as follows. The Tray Sizing window should appear. Do not save the file to the default location.
The completed Basis tab appears below. The vapour residual is rich in ethylene but also contains recoverable ethylene oxide. For this case, no information is supplied on the last page of the Input Expert, so click the Done button. The less efficient a pump is, the greater the increase in the temperature of the fluid being pumped. Click the Variables tab, then select the Units page.
The enthalpy is the combined feed enthalpy plus or minus the duty. Click the Clone button. Then, turn casse into a template. A case study of biodiesel production. Defining components list and fluid package 2. Using Peng-Robinson equation of state as a fluid package, determine the outlet temperature of the natural gas.
Tools and Tricks
hhsys You can give your fluid package a name at the bottom of the fluid package screen e. This observation is in conformity with the finding of  who observed that increase in feed flow rate increased the product RVP. Ensure that you delete them once this exercise is finished. Scroll down and select Tray Sizing. N2, CO2, C1 – C8. A template is created just like any other case in fact, any simulation can be converted to a template to be used in another simulation.
From the list of fluid packages, select the desired thermodynamic package.
Note that a total condenser does not count as a stage. It is believed that once these foundations are well understood, the student will be able to learn advanced topics easily by using the information in the Help menu.
The Workbook is designed for this purpose and extends the concept to the entire simulation. Fluid Package window will be opened. There is no phase change in the Reactor under isothermal conditions since the flow of the vapor product stream CSTR Vent is zero. The low and high bound for yhsys primary manipulated variables were selected and set as shown in Figure 5.
A drop down menu box will appear in the window. In addition to displaying stream and general unit operation information, the Workbook is also configured to display information about any object type streams, pipes, controllers, separators, etc. Click on the Prop Pkg tab. The pump increases the pressure of the liquid.
Assuming that all of the units operated at atmospheric pressure, determine the species flow rates in every stream. The units should be in per cent as shown in Figure Reference  studied modelling and optimization of fluid catalytic cracking unit using Hysys.
hysys simulation case study
Neither the components nor the mixing process need be ideal, since HYSYS can compute the chemical activity of each component in the mixture based on mixture and pure component fugacities. The less efficient a compressor is, the greater the increase in the temperature of the gases being compressed.
The Session Preferences property view appears. Remember me on this computer. To make the reactions operate sequentially, in the Oxidation Rxn Set, click the Ranking… and enter the information as shown: It can be hyzys as a textbook in freshmen chemical engineering courses, or workshops where HYSYS is being taught.

For this case, no information is supplied on the last page of the Input Expert, so click the Done button. It is therefore necessary to process the produced fluids in the field to yield products that meet the specifications set by the customer hsyys is safe to handle .
Define the inlet and outlet conditions for the streams as given in the problem statement. The final task is to make the set available to the Fluid Package, shudy also makes it available in the flowsheet.
