1. Introduction to Version 3.4

 

Welcome to HYSYS Version 3.4 – HYSYS 3.4 is the fourth minor release on the HYSYS 3 series and offers significant advancement in simulation technology. As with every AspenTech product, it reflects our commitment to delivering Process Asset Lifecycle Management within a platform that is the world leader in ease of use and flexibility, and sets the standard for an open engineering environment. This version provides the technology framework to support Steady State process design, Dynamic operability and management, Asset Planning and Utilization and Online Optimization. This allows you, our customer, to further leverage your modeling investment to obtain real business benefits.

 

HYSYS 3.4 was designed with three main purposes in mind. Firstly, to expand and improve the Upstream options by providing new upstream thermodynamic capabilities and improved integration with well and flow line modeling tools. Secondly, to provide the foundation HYSYS environment that is compatible with Aspen AssetBuilder. Thirdly, to continue to add engineering enhancements for both steady state and dynamics that will enable users to extract more value from HYSYS.

 

 

2. HYSYS 3.4

         

a)  New Features

 

 

HYSYS Upstream

AspenTech is excited to deliver the second phase of HYSYS Upstream with the release of HYSYS 3.4. The purpose of HYSYS Upstream is to extend the upstream capabilities of the HYSYS simulation environment. These improvements introduced in HYSYS Upstream are in two main areas, thermodynamics and hydraulics. Thermodynamics: HYSYS Upstream delivers new capabilities to utilize the key upstream thermodynamic methods, Black Oils and PVT. New tools for Lumping and Delumping hydrocarbon components have also been developed. Hydraulics: HYSYS Upstream delivers mechanisms for integrating with production field models built in industry leading well and flowline modeling tools. This includes PIPESIM from Schlumberger, ProFES from Aspen Technology and OLGA 2000 from Scandpower. Using the HYSYS Upstream options will allow consistent thermo and models across an integrated asset. These holistic models create powerful tools to make better decisions on Oil and Gas assets to improve the return on capital employed. There are two HYSYS Upstream Option one for Steady State and another for Dynamics capabilities.

 

Black Oil Methods and Thermodynamics

Black Oil is a physical and transport property model for petroleum fluids commonly used in the Upstream Oil & Gas industry. Black Oil methods are used to model the behavior of petroleum fluids when a compositional analysis is unavailable or impossible to obtain. Given readily available information such as specifics gravity of the Oil, Gas and Water phases, the Solution GOR, WOR, T, P and Flow the fluid characteristics can be predicted. The Black Oils implemented in the HYSYS Upstream Option are based on the industry leading methodologies developed by Neotechnology. In version 3.4 the Black Oil package is also supported in Dynamics.

 

Black Oil Flowsheeting

With the HYSYS Upstream Option the Unit Operations will work in both the standard Compositional and Black Oil modes. Black Oil mode flowsheeting involves advanced methods for blending different Black Oil stream in operations with multiple inlets. Most of the HYSYS Unit Operations work in Black Oil mode and they include: Stream, Valve, Heater/Cooler, Mixer, Tee and Pipe Operation.  In version 3.4 these unit operations will also run with Black Oils in Dynamics.

 

Black Oil Translator

As your Oil & Gas flowsheet moves further downstream into Separations equipment it becomes more and more necessary for a compositional model to accurately model the processes. A key bridge from the Black Oil model to a Compositional model is the Black Oil Translator. The Translator has two options to span this divide. The Simple Transition requires the user to specify a known composition in the outlet stream and just transfers the mass flow and flash specifications to the Outlet. Alternatively the more advanced “Three Phase” transition can be selected. This Transition uses a specified Gas Composition and the Oil Characterization capability to generate the outlet composition. The Auto Cut or User specified cut points can be used to determine the number of pseudo components generated. The “Adjust Light Ends” option can be used to distribute any overlapping pseudo components into the pure light end components. For version 3.4 we have added a third option for translation, which is to use Infochem’s black oil translation methodology.

 

Component Lumping/Delumping

In large complex Oil and Gas flowsheets involving hypothetical components it is often beneficial to reduce or increase the number of pseudo components being used to represent the petroleum fluids. Different reservoir fluids that are characterized from PVT packages and the Black Oil Translator may need to be consolidated into one lumped component slate to improve usability and performance. It is also often necessary to reduce the number of components to increase model performance and convergence. Other times more components are required to accurately model separations. The HSYSY Upstream option has the ability to perform such tasks. The Lumper/Delumper operation can be used to either increase or decrease the number of pseudo components in the flowsheet while maintaining integrity of the component property data. For HYSYS 3.4 the Delumping method has been improved to utilize HYSYS’s oil characterization methods to expand the hydrocarbon component slate.

 

PVT Environment

In version 3.4 the integration of PVT engines has been significantly improved. The new version provides a PVT environment from which multiple oil characterizations can be created from different PVT packages. Currently, InfoChem’s Multiflash product is available in this environment along with an interface to Calsep’s PVTSim characterizations. Lab data from PVT analyses is entered into Multiflash or PVTSim in order to characterize reservoir and production fluids. This fluid characterization is then imported into HYSYS to the PVT environment. Once inside HYSYS the user can choose to use the generated components and EOS for thermodynamic calculations.

 

PVTSim Interface

PVT characterizations performed in Calsep’s PVTSim package can be imported into HYSYS’s PVT environment. (See above).

 

PIPESIM-NET Operation

The PIPESIM-Net integration now works in both Compositional and Blackoil modes. At this time the Blackoil mode works only one way from PIPESIM to HYSYS.

 

Aspen Hydraulics - Network Solver

HYSYS 3.4 now offers the ability to solve a network of pipes inside the HYSYS environment. This pipe network capability is provided in a sub-flowsheet called Aspen Hydraulics. This subflowsheet provides an area to configure and solve complex networks of pipes from a subset of unit operations. The hydraulics subflowsheet is designed to solve in steady state, and that solution can then be used to initialize a dynamics simulation. The Aspen Hydraulics subflowsheet is found on the Upstream operations palette.

 

OLGA 2000

The HYSYS Upstream Dynamics option now comes with a runtime interface to Scandpower’s OLGA 2000. This allows the user to create integrated dynamic models of multiphase flow lines connected to the facilities. The OLGA link connects a dynamics HYSYS model of the facilities with the pipeline model running in the OLGA 2000 application. The OLGA link is found on the Upstream palette.

 

Asset Builder Support

HYSYS 3.4 is fully compatible with Aspen’s Asset Builder, a main component of the Aspen Oil & Gas Solution. AssetBuilder allows asset teams to build integrated models of their production systems from the reservoir all the way to the back end of the facility. HYSYS 3.4 has the necessary interfaces and mechanisms for exchanging information with AssetBuilder in order to build compound models. Contact AspenTech for more information on AssetBuilder and the Oil & Gas Solution.

 

Engineering Enhancements - Steady State

 

Hydrocyclone

A new unit operation, the Liquid Hydrocyclone, has been added for modeling liquid-liquid separations. This Hydrocyclone model takes into account liner types and particle size distribution to calculate the performance of the liquid-liquid separation. This operation can be used to model many of the hydrocyclone processes prevalent in the Oil & Gas industry for separating water and oil. The new liquid hydrocyclone model is found on the Upstream operations palette but does not require the HYSYS Upstream options license.

 

 Depressuring Enhancements

There have been many improvements to the depressuring utility.

 

Three Phase Envelope

The Envelope utility has been enhanced to calculate three phase envelopes. Previously the envelope utility performed calculations on a dry basis only by removing the aqueous stream. Now the utility will calculate the envelope curves for the 3-phase system. The 3-phase option can be activated by selecting the “COMThermo Three Phase” option from the drop down on the design tab and Connections page. For best results, it is highly recommended that the 3 phase option is used along with a stream that is using a COMThermo Fluid Package.

 
Master Phase Envelope

A new utility for viewing the phase envelopes of multiple streams side by side has been delivered. From the Tools menu select the Utilities item and then choose the Master Phase Envelope from the list of available utilities. This utility gives the user the ability to select multiple material streams and calculate the phase envelopes for each and display them on the same plot. The Master Phase envelope calculates and displays the 3 phase envelopes for the streams selected. The results can be viewed in both tabular and graphical format. Again, for best results, it is highly recommended that this utility is used along with streams that are using a COMThermo Fluid Packages.

 
Property Packages

The PRTwu, SRKTwu and TST Packages are now part of the standard set of fluid packages available in the Basis environment. These packages were only available as extensions in the previous versions.

 

Partial Light Ends Input

A new option in the oil characterization methods for using incomplete light ends input. If only partial light ends data is known for an assay, use the “Allow Partial Light Ends Input” option in the Light Ends Handling and Bulk Fittings dialog.

 

Cut Copy Paste Preferences

A new preference option has been added to avoid duplicate labels, when using cut/copy/paste to add streams and unit operations to another flowsheet. This preference option allows the user to append a prefix label to all streams and operations pasted into a new flowsheet.

 

Amines - Approach to Equilibrium

A new capability has been added to the HYSYS column when using the Amines package. This new functionality will calculate the approach to equilibrium for the amine contactor.

 

 

Engineering Enhancements - Dynamics

 
Compressor Inlet Guide Vanes

The compressor operation has been enhanced to include the ability to model inlet guide vanes. This approach requires compressor curves for different guide vane settings. The compressor will then interpolate between the curves to calculate the compressor performance at the specified guide vane setting.

 
Electric Motor for Rotating Equipment

Electric motors for pumps and compressors can now be modeled in HYSYS Dynamics. The user must supply a speed versus torque curve for the electric motor to allow HYSYS to rigorously and realistically model the startup of rotating equipment.

 

Dynamic Pipe Segment

The basic pipe segment unit operation now works in dynamics mode. The pressure drop in the pipe can be calculated using a fast approximate method or by using the steady state correlations. Elevation changes can also be modeled in dynamic mode. This is a simplified approach to modeling pipes and pipelines in dynamics mode. It is important to note that the results are not rigorous; it does not perform momentum balances, shock waves, slugging or choking calculations. For rigorous modeling of multiphase pipelines it is highly recommended to use the hydraulics subflowsheet, ProFES or the OLGA link. 

 
Valve – User Characteristic Curve
In Dynamics mode the user can set the operating characteristics of the valve to quick opening, equal percentage or linear. There are many other types and variations on the behavior of valves in operations. In version 3.4 the user can now enter a user characteristics curve to effectively model any valve opening characteristics. 

 

Valve Types
Many more manufacturer types are available to select in valve unit operation.
 
Digital Operation – Dead Band

The digital logical operation now has the ability to use a higher and lower dead band. This will provide the digital point with a buffer so that it does not switch on and off due to process noise.

 

Surge Controller

Under surge control parameters you can now make use of a higher order polynomial to calculate the surge flow from the head.

 

Kettle Option

Kettle Chillers or Reboilers can now be modeled using a new option in the Separator unit operation. In Dynamic mode when this option is selected, two new streams must be connected to the vessel. These streams represent the inlet and outlet of the utility stream. This option also allows the user to model the utility stream in a tube bundle running through the vessel. The heat transfer between the contents of the vessel and the utility stream will take into account the liquid level in the vessel.

 

Other new Capabilities

 

Case Security

The Case Security capability allows a model author to password protect the model for end user use. The model author must supply a master password and an end user password. The user can also restrict the end user from accessing certain model parameters, basis information and flowsheet topology. This capability is also supported through automation so that password protected models can be loaded providing the appropriate password has been supplied.

 
Drag Mode – PFD

Using the new Drag mode icon in the PFD, the entire flowsheet can be dragged to a new location. This feature can be used to quickly move or reposition the flowsheet in the PFD.

 

Neural Net Manager

A Neural Net Manager has been added to manage multiple neural net representations in flowsheet. This management tool enables the user to set ranges over which a specific neural net model applies, thus allowing the manager to switch to the appropriate neural net model

 

Training

AspenTech is now taking a new approach to customer education, training and technology transfer. We are looking at new ways to deliver training to our customers which will include self training, animated tutorials, computer based training, web based training, class room training and project training. As a start we are making our training materials publicly available to facilitate self-training and in-house training. From within HYSYS go to the Help menu and select the Training item. This will lead you directly to the Aspen Training Centre website and all the relevant training materials of the HYSYS product. The materials include full course materials and modules and animated tutorials. From the Training Centre website you can browse to training materials available for all other AspenTech products.

 

 

b)  Rectified Issues

1.      Hydrate Prediction – a problem with predicting hydrate formation temperatures in the under saturated region has been addressed.

2.      Depressuring – a conversion problem with the “Fire API521” operating mode, which caused errors in the calculated duty has been remedied.

3.      Depressuring – when using the Fire Wetted heat flux equation, the wetted area is automatically calculated to match the initial liquid holdup in the vessel.

4.      Worksheet Properties – The Properties page on the worksheet tab of all unit operations will now reflect the properties displayed by the correlation sets of the attached material streams.

5.      The LNG usability has been improved with some additional plots.

6.      The feeder block now has some additional user warnings and diagnostics.

7.      Electrolytes – better warning have been added in the HYSYS Electrolytes OLI option to notify the user when the stream conditions are outside the range of applicability.

8.      The Act. Gas Flow is properly reported in the bulk stream when the vapor phase fraction is equal to 1.

9.      Esso Tabular – both the standard and COMThermo implementation of this property package is available.

10.  Amines 3 phase flash – a problem was fixed in the 3 phase amines flash and as a result the aqueous phase resulting may be different from the aqueous phase calculated in previous versions.

11.  Cut\Copy\Paste – Custom Icons are no longer lost while performing cut/copy/paste operations in the PFD.

12.  Liq Vol Flow @ Std Cond variable in the stream now supports kbpd. Kbpd = 1000 bbl/d

13.  Strip Charts are now properly imported in templates.

14.  The compositions on the Compositions page of the Workbook can now be properly displayed by selecting the choices for different fluid package.

15.  Implicit Check valve

16.  The Esso Tabular property package now works properly under COMThermo

17.  The BIPs for Water and Ethanol were improved to better represent the VLE of these systems.

18.  Dynamic initialization has been improved to be able to manipulate groups of objects in order to better support large places.

19.  Solid components are now properly handled in Dynamics.

 

 

c)   Known Issues

 

For the most up to date list of known issues and work-arounds visit the Knowledge Base at: http://support.aspentech.com  

 

1.      Microsoft.Net must be installed with HYSYS 3.4. This is handled by the installer. If the user cancels out of the .Net installation then the HYSYS install will be cancelled.

2.      Hydraulics subflowsheet – when solving a network of pipes in this subflowsheet the composition, flow and enthalpy must be supplied at the inlet boundaries and the pressure specification at the outlet boundary must also be supplied.

3.      Black Oils – The conditions page on the worksheet tab of unit operations displays the wrong values for flowrates when using a black oil fluid package

4.      Black Oils – The wrong values for Mass and Molar flowrates appear in variable flybys in unit operations and the PFD when using a black oil fluid package.

5.      Property Package Extensions – Your custom property package extensions MUST be recompiled against the HYSYS 3.4 Type Library to ensure that they properly function with version 3.4 if they were last compiled against the HYSYS 3.0.1 type library. Property Packages last compiled against v2.4.1 do NOT need to be recompiled for v3.4

6.      The old Depressuring utility has been intentionally removed in favor of the newer Dynamics Depressuring utility. The old utility can still be used in older versions.

7.      Black Oils: Vapor only Black Oil streams do not represent the VLE behavior of the stream. This is because the black oil methods calculate the amount of gas present from correlations of dissolved or solution gas. This will problem will be evident in the vapor phase exiting a separator, where the user will notice that under no conditions will a liquid phase condense.

8.      PIPESIM 2003 links: The new links to PIPESIM and PIPESIM-Net are designed to work with the PIPESIM 2003 version.

9.      Solid Unit Operations are not supported in Dynamics.

10.  Tool Tips: If HYSYS 3.4 is started for the first time after installation and a user’s preference set is loaded the Tool Tips may have duplicate values being displayed. To avoid this, after installation load HYSYS and then exit before loading a user preference set. If you already have duplicate values in the Tool Tips, find the ToolTip.xml file in the Cases directory and delete it. Next start HYSYS and exit. This will create a new ToolTip.xml file without the duplicates.

11.  MSXML Parser - During the installation of HYSYS 3.4, users on different language versions of Windows (Japanese, Korean, Chinese) may experience problems with the registration of MSXML4 (the Microsoft XML parser). Should you experience this problem, simply go to the MSXML folder on the CD, open the folder corresponding to your language, and run the standalone MSXML installer within that folder.

12.  XML – Extension Property Packages, Extension Unit Operations and User Variables are currently not supported by the XML file input/output systems.

13.  XML – Not all calculated data is available in the xml output file.

14.  XML limitations – Cases can be saved in XML format in Dynamics mode but not enough information is stored at this time to fully reload the case. COM Thermo specific data is not output to XML. A HYSYS case using COM Thermo will not reload all the COM Thermo data.

15.  Stream Correlations – Some stream properties are currently not supported in the correlation manager but they can still be accessed via the workbook and PFD tables.

  1. Security – Infrared ports setup for PDA devices may interfere with SLM keys.
  2. Security & Automation – Automation applications in VB, Excel or Word may not successfully achieve a license when the LSHOST environment variable is defined in the User Variables section as opposed to the System Variables section.

Upgrading From HYSYS v2.4 or Higher

If you have installed HYSYS v2.4 or higher, you are already using the SLM Security system.  You are receiving HYSYS 3.4 as a regular update so you will not receive a new key or license file; there is no need to install new licenses during the installation. There is no need to update your license server if you are using network security. Proceed with the Installation instructions in the SLM Installation and Reference Guide.

 

Upgrading From HYSYS v.2.2.2 or Older

Older versions of HYSYS used a different security system. Standalone users can proceed with the HYSYS installation described below; green keys will work with HYSYS 3.0 and continue to function with your old HYSYS version. New parallel port SLM keys will only work with HYSYS v2.4 or higher. If you are using Hyprotech’s old network security you will need to upgrade your network security to use HYSYS 3.0. Please refer to the SLM Installation and Reference Guide for Upgrading Your Network Security instructions before installing HYSYS.

 

New HYSYS 3.4 Customers

Welcome to HYSYS. You will have received a new Grey SLM key(s) and license file(s) along with your documentation and Software. For Network security, a SLM License Server must be set up by following the instructions in section 2.2.5 of the SLM Installation and Reference Guide. To install HYSYS, refer to section 1.4 in the same manual.

 

 

 

4. SLM Security System

Software License Manager (SLM) Security System

HYSYS version 2.4 and above uses a new security system that has been implemented in all Hyprotech products. The new SLM security system uses a license file that contains the list of software and features you are licensed to run. The key is simply a locking device and no longer contains licensing information. The SLM offers many advantages over the old Hyprotech security system, including simpler installation, easier upgrades and improved diagnostic tools. Previous versions of HYSYS had two types of installations, one for network users and a separate one for standalone users. A security code was entered during the installation process that defined the type of installation being performed. This distinction meant that the type of security being used could not be easily changed. With the SLM only one installation is required, regardless of how HYSYS is being accessed. The only factor determining the licensing mode you will be using is the location of the license file and security key. Thus, license modes can be mixed between standalone and network without modifying HYSYS. Your license files control all features that constitute these applications. Upgrading to new features is as simple as changing the license file.

 

5. SLM Security System FAQs

1)     Can I use the same server for the old and new network security systems?

-Unfortunately, no. The new SLM network security and the old network security systems are not compatible. The SLM security system must not be installed on the same computer as the old network security system.

 

2)     How do I know if my license file and key are matched?

-The license file on your disk will be named according to your serial number (for standalone “green” keys) or lock code (for standalone or network SLM/USB keys).

 

3) With the new system will I still be able to move the key around?

-Yes. However as each key is configured for a specific license file, you must install all license files you will be using with the application. To do this, simply select all the license files at Step 7 in the “HYSYS Installation Procedure” outlined below. It is also possible to add these files later by following the instructions in the SLM Installation and Reference Guide.

 

4) I need a license file. How do I get one?

-You should have received a license file on disk with your copy of the software. Alternately, if your company is running a network version of the program, the server will contain the required license files. Otherwise, contact your local Hyprotech sales representative. If you are unsure whom to contact, Technical Support can put you in contact with someone. The request must include the serial number and lock code for your key. The lock code can be determined by running the echoid32 software as described in the SLM Installation and Reference Guide. Please install the license file as outlined in the SLM Installation and Reference Guide.

 

5) How can I tell what licenses I need to run a case?

-If you are running v2.3 or later of HYSYS, use the HYSYS file picker (select from the Preferences \ File options). This file picker view will show you which version a case was saved in and which licenses are required to run the case. Please be aware that when you save a file using licensed features, you cannot open it again without those licenses.

 

6) I need some features I am not currently licensed for. How do I get licensed for new features?

-Contact your local Hyprotech sales representative. If you are unsure whom to contact, Customer Support can put you in contact with someone. You will also need to replace your current license file with a new one. If you do not have one, please refer to “I need a license file. How do I get one?” for details on how to obtain one. If you are running an old version of HYSYS or other AspenTech software, which does not support the use of license files, you will be required to exchange your current network grey key for a new network SLM key with updated license information.

 

7) What if I need to use an older version of the program?

-If you have a standalone “green” key, you will still be able to use your copy of the program. If you were on a network, you will need to speak with your sales representative to arrange for a temporary key.

 

8) What if I need to install another Hyprotech product and it has a new license file?

-Allow the installer to add the new license file. It will place the files in the appropriate location to ensure that everything works together.

 

Further information can be found in the Troubleshooting section of the SLM Installation and Reference Guide.
