Problem Statement: Psychrometric charts are widely used to calculate the properties of air-vapor mixtures. Quite often, we are asked if Hysys calculations match the Psychrometric Charts, especially enthalpy. Hysys and Psychrometric Charts enthalpies cannot be directly compared because they use different basis. This | Solution: shows how Hysys enthalpies can be converted to the basis used in the Psychrometric Charts. An excellent agreement is found when the converted enthalpies are compared.Solution
The enthalpy of formation at 25 degrees Celsius for each pure component is used as the reference state in Hysys on the enthalpy calcula... |
Problem Statement: What is the meaning of the PV Work Term Contribution used by Aspen HYSYS? | Solution: The PV work term contribution is a coefficient that allows the user to tune the energy balance equation to reflect the actual behaviour.

Problem Statement: How do I model variable volumes in HYSYS dynamics? | Solution: Although the vessel volumes in HYSYS dynamics are typically fixed values, it is possible to model variable volume systems. The key to modeling a variable volume system is to be able to calculate the vessel volume as a function of an independent variable.
In the attached model an equation in a HYSYS spreadshee... |
Problem Statement: The customer uses Collaborative Demand Management (CDM) and has a number of DM models for its Business Units (BUs). There is a problem getting one of the DM models to publish to CF.
A message displays saying that ...a unique constraint has been violated.

1. All attributes are categorized into base attributes and common attributes.
2. Values (codes) from all base attributes make up base keys.
3. Those keys need to be distinct across all busine... |
Problem Statement: Does the energy balance in the Reactor include the Heat of Reaction? | Solution: Yes. The steady-state Reactor energy balance is defined as
Duty = Hvapour + Hliquid - Hfeed, where
Duty = The heating (+) or cooling (-) by the optional energy stream attached to the Reactor
Hvapour = Heat flow of the vapour product stream
Hliquid = Heat flow of the liquid product stream
Hfeed = Heat flow of ... |
Problem Statement: Why is the pressure in my vessel different from those in the attached streams? | Solution: This situation is likely to arise when Static head contributions are enabled.
In HYSYS Dynamics the pressure of a stream is taken at the point where it comes from, not where it is going to. The pressure of the vessel contents is the pressure of the vapour product stream. The pressure of the vessel feed stream... |
Problem Statement: Can I bring an open case to the front within HYSYS using OLE Automation? | Solution: In the HYSYS interface if a case is open but not showing, it can be activated (brought to the front) by using the Load Workspace option on the Window menu. It is also possible to activate the case through OLE Automation.
The Excel VBA code below illustrates a function that will activate (i.e. bring to the fro... |
Problem Statement: Can Aspen HYSYS calculate the Methane Number of a stream? | Solution: Aspen HYSYS has no built in feature to calculate the Methane Number of a stream. The user should use a spreadsheet to calculate the methane number from an appropriate equation. If you want to calculate this number for many streams in a simulation, we would recommend programming a user variable for it (seeSolu... |

Problem Statement: How do I display or plot a rolling average for a tag? | Solution: To display or plot a rolling average, use an ad-hoc calculation with the AspenCalc function MovingAverage in place of a tag name. MovingAverage has two arguments: Tagname and AverageInterval expressed in hh:mm:ss format.
For example, entering
=MovingAverage({ATCAI},00:15:00)

Problem Statement: Visual Basic code that works in version 2.5.1 does not work in version 5.0.1. Is there an example available that shows how to insert data in the database in version 5.0? | Solution: The reason why the visual basic code created in version 2.5.1 does not work in version 5.0.1 is because the at_tag control was retired after version 2.5.1. It was replaced with a more flexible architecture that enables Process Data to talk to many different types of data sources and not just InfoPlus.21.

Problem Statement: Users who have created custom formulas on the Calc server are unable to make use of it as an ad-hoc calculation in APE on the client PC. The error Invalid Tag may appear. However, using built-in formulas in the ad-hoc calculation is successful (eg. =abs(tag1)). | Solution: In order to use formulas with ad-hoc calculations, Aspen Calc must first be installed on the client system. When you install Calc on the client the built-in formulas are also installed. But in order to use custom formulas created on the server, you have to copy the library that contains the custom formulas on... |

Problem Statement: For a liquid stream of liquid and aqueous phases present at standard conditions, HYSYS calculates the Actual Volume Flow of the overall stream when the stream temperature and pressure is set to the standard conditions. The value does not match the Liq Vol Flow @ Std Cond of the overall stream. Why? | Solution: All calculations for volumetric stream flows are based on density. For a liquid stream, the actual volume flow is calculated based on the actual liquid density while the Liq Vol Flow @ Std Cond is based on the Liq Mass Density @ Std Cond.
HYSYS uses the internal methods of the chosen property package to calcu... |

Problem Statement: Using Aspen SQLplus iq.exe command line program to run a simple command from Aspen BCU Administrator will need to create a sql file. If there is a stored procedure in IP.21, is there any way to run it without creating a sql file? | Solution: Use Aspen SQLplus sqlplusx command line program. This program allows the running of SQL query on a computer without IP.21 installed.
For example, a Stored Procedure call list_trend_values which accept 2 parameter, a record and a timestamp is created in the IP.21 database. The following is added to the BCU com... |
Problem Statement: Why is the IBP/FBP (obtained from TBP/D86/D1160(atm)) not matching with the bubble/dew point of my oil? | Solution: The IBP that you see in the Oil Environment under the Blend View --> Property Plot (or in the BP Curves utility) will be different than the bubble point at atmospheric pressure (in the simulation).
This is a common misconception. Let us say you have distillation data from 3 different lab analysis techniques; ... |
Problem Statement: BCU Administrator fails to load, error is:
Failed to retrieve batch area. B21BAI-60174: Specified area is not defined | Solution: There are several possible causes of this error:

Problem Statement: For writing equations to the pressure flow solver in dynamic mode extensions, people feel they can not use pressure and flow balance equations because Hysys does not give you a chance to update the equation coefficients and constants. So they always use general equations as a workaround. However, gen... | Solution: For flow and pressure balance equations, you can initially set the coefficients and constant values in the extension when the equations are constructed. After that it will not periodically ask you to change them but you can change the coefficients and constants when you want to. For example, you may choose to... |
Problem Statement: How can I use HYSYS OLE to efficiently create case studies? | Solution: The use of OLE functionality can greatly increase the speed with which case studies can be created within HYSYS. By utilizing nested FOR loops, multiple states can be easily and efficiently defined, thereby reducing the effort required to develop related process models.
