Problem Statement: Similar to Aspen Plus behavior, a HYSYS model that uses EO subflowsheet usually generates a number of temporary files in between runs. But unlike Aspen Plus, the temporary files are not in the same folder as the model file.
Where are these files located on my hard drive? | Solution: They are located at the Temp folder of the logged-in users' profile folder, for example, C:\Documents and Settings\songt\Local Settings\Temp.
Keywords: Temporary files, EO, equation oriented, Aspen Properties

Problem Statement: Are there any example files describing Liquid - Liquid Extraction in Aspen HYSYS? | Solution: In the attached word document tutorial, a simple liquid-liquid extraction process in HYSYS is explained.
A liquid stream containing 60 mol% water and 40 mol% acetone entering at 25 C, 1 atm, and flowing at a
rate of 1 kgmol/s will be extracted with a pure MIBK stream at the same exact conditions as the feed.

Problem Statement: When I use the ATDSP | Solution: s function, I only get one row of data even though the PrSolution table in the Results.MDB file has 49 rows. However, when I use the ATDSQuery function with the stored RW_Solutions query, I do get a dataset with all 49 rows. Why is this?
For example: Use the attached template with the attached Results.MDB... |
Problem Statement: How to model sea water. | Solution: Modeling of sea water really depends on what process parameters you are trying to get out of the simulation. ThisSolution applies to the case in which a non-electrolytic system is created.
First create a hypo component by cloning the pure water library component. After this, the thermal properties of the clon... |

0 = Liquid Only
1 = Vapor Only
2 = Two Phase
3 = Elongated Bubble
4 = Stratified
5 = Slug Flow
6 = Wave Flow

Problem Statement: In strip chart, I have activated variable Vessel Inner Wall Temperatures (Vapor)/(liquid1)/(liquid2) but it is displayed as <empty> even after running the depressuring utility. why? | Solution: If you use heat loss model as 'none', the inner wall temperature result will be 'empty'. Wall temperature is only considered when using the 'Detailed' Heat Loss model, otherwise heat transfer to the wall material is not considered and therefore wall temperature is not reported. It is the only model that divid... |
Problem Statement: When user is trying to load DBR PVT Pro Engine (Window Vista or Window 7) in the PVT Environment, an error appears saying 'PVTProExtPkg setup is not successful. | Solution: This is likely due to an error in the registry from installation and there is a workaround the user can do to fix the registry key by following the steps:
1. Open the registry by opening the start menu and typing regedit in the Search programs and files field
2. Allow the program to make changes to the regis... |
Problem Statement: Where can I check Condenser and Reboiler heat curves? | Solution: Condenser and Reboiler results can be viewed directly inside the Column Environment. To enter the Column Environment, open the column property view and click on the Column Environment button. Once inside the column subflowsheet, double click on either the Condenser or Reboiler PFD icon to open the correspondi... |
Problem Statement: This document will help user set up DBR Amine package for amine process modeling. | Solution: The attached document gives step-by-step instructions on setting up DBR Amine package in Aspen HYSYS.
Keywords: Amine, DBR Amine
References: None |
Problem Statement: Absorber column using DEA and Amine Package fails to solve when the feed rate is changed in a large step. | Solution: When the feed rate (eg, sour gas molar flow) is changed in a large step the solver encounters oscillation during convergence. To prevent instability change the damping factor from a default value of 1.0 to a smaller value typically in the range of 0.2 - 0.4.
The damping factor can be found via the Parameters ... |
Problem Statement: How do I prevent the error message the polytropic head factor beign at lower limit or at higher limit? | Solution: The Polytropic Head Coefficient of the compressor has lower and upper limits as 0.6 and 1.4. When the calculation of Polytropic Head Coefficient reach 0.6 and 1.4 limit, the Polytropic Head Coefficient will be set to 0.6 and 1.4. If you want to make sure the Polytropic Head Coefficient calculation not reach t... |
Problem Statement: What is the assay data basis used for oil characterization in Aspen HYSYS?
This | Solution: is intended to clarify the assay basis used for molecular weight, density and viscosity curves (the dependent or independent) in the oil manager.Solution
The assay basis for distillation data can be selected from the drop down options. This can be selected as liquid volume, mass or mole basis. But when you en... |
Problem Statement: How to choose the right RVP method and why it is not solved sometimes and shows empty. | Solution: Aspen Hysys provides different methods to calculate the RVP value. The choice of methods is dependent on your applications and stream conditions. Please refer the following information to choose the correct method.
1. HYSYS RVP Method
The RVP calculation in the HYSYS Cold Properties and Boiling Point Curves u... |
Problem Statement: How to setup a yield shift reactor? | Solution: Yield Shift reactor (YSR): The Yield Shift reactor (YSR) unit operation supports efficient modeling of reactors by using data tables to perform shift calculations. For example if the reactor output is available at three different temperatures say 500C, 600C (base data) and 700 C, then using the linear relatio... |
Problem Statement: How can I add a solid component in Aspen HYSYS? | Solution: Solid components can be added in two different ways in Aspen HYSYS: as a component from the databank or as a Hypothetical component if its properties are known. The guidelines are provided below.
1. Add a component list on the Components tab of the Simulation Basis Manager window in the Basis environment. T... |
Problem Statement: When I double-click on a unit operation or stream icon in the PFD window, Aspen HYSYS does not appear to respond. | Solution: Aspen HYSYS may appear to not respond because the corresponding window was already open in another location within the application desktop (you can verify this by selecting Windows | Arrange Desktop from the main menu). The easiest way to resolve this problem is to first of all close all windows (choose Windo... |
Problem Statement: What does the Apply smart bulk fitting on molecular weight and mass density option do? | Solution: The Apply smart bulk fitting on molecular weight and mass density checkbox can be found on the Light-Ends Handling & Bulk Fitting Options window as shown below. This form is instantiated via the Assay view available in the Aspen HYSYS oil manager.
In most circumstances, activating the Apply smart bulk fit... |
Problem Statement: In a column property view | Performance tab | Plots datasheet, and under Tray by Tray Properties, if we select Light/Heavy Key, and click on View Table button, we get Profile Table: Light/Heavy Key Profile dialog. Furthermore, if we click on Properties button located at the lower left corner, we get ... | Solution: First, we give a brief discussion of light and heavy keys in distillation column design. For binary distillation, the light key refers to the component with lower boiling point, and the heavy key is the second with higher boiling point. The concept can be used for multi-component mixtures. In these cases, we ... |
Problem Statement: TheCase Security option doesn't appear in Tools menu for the case protected with password but it appears for a new case or a case that it not password protected. Why? | Solution: You need a Master password to be able to access the Case Security features in a password protected case file. If you supply a user password instead of a master password, HYSYS will not show Case Security option to
the user.
When opening a case that is password protected, you have two options:
1) Enter the Use... |
Problem Statement: Why is the cooler duty not equal to mCp*DeltaT? | Solution: The heat flow in the cooler is calculated based on the enthalpy difference between the inlet and the outlet and not using the specific heat (cp). The enthalpy is calculated from the fluid state (Temperature, pressure and composition) using the specific property method selected. The calculated heat flow is the... |
Problem Statement: How is the reflux ratio defined in full reflux tower? | Solution: In case of total reflux, reflux ratio (RR) = R / V, where R is the reflux molar flow rate and V is the molar flow vapor rate.
