HYSYS 3.2

####

New Features

##### Aspen Engineering Suite Integration

Aspen WebModels

- The user has the ability to author Aspen WebModels from within the HYSYS simulation environment. The Process Data tables are used to define the table of input and output parameters that will be visible to the user in the published Webmodel. Once the Process Data table is configured in the Databook, select the Publish Webmodel button. This will generate an XML file that can be exported to Aspen Webmodels to deploy the model to other users within your organization. Aspen Webmodels is an excellent tool for distributing the power of simulation models to non expert users. See our website at www.aspentech.com for more information on Aspen WebModels.

Aspen Enterprise Engineering

- HYSYS 3.2 will be able to run under the Aspen Enterprise Engineering platform, AEE. AEE is a Citrix based system for deploying the Aspen Engineering Suite within an organization. Using AEE, HYSYS is installed on a server through which users access the software. No local installations on user desktops are necessary. See our website at www.aspentech.com for more informantion on Aspen Enterprise Engineering.

Aspen OnLine

- HYSYS models can be connected to live plant information systems through Aspen OnLine. Aspen Online uses CIMIO to connect to numerous Plant Information and DCS Systems including Aspen's IP21. The ability to connect HYSYS simulation models to live plant data enables high value activities such as Performance Monitoring, Soft Sensors, Safety Surveillance and Optimization. See our website at www.aspentech.com for more informantion on Aspen Online.

Aspen Custom Modeler

- Aspen Custom Modeler is the easy to use custom modeling environment for the Aspen Engineering Suite. Custom user models built in ACM can now be exported to the HYSYS simulation environment and run in both SS and Dynamics. The ACM Operation within HYSYS allows the user to select and import models built in ACM. The Operation identifies the connections between HYSYS streams and ports in the ACM model. The Operation also provides a composition map to resolve differences in HYSYS and ACM property packages. This addition gives HYSYS yet another means to customize and extend HYSYS simulation models to meet your specific simulation needs. See our website at www.aspentech.com for more informantion on Aspen Custom Modeler.

Aspen DMCPlus

- Aspen's Advance Process Controller, DMCPlus, has been integrated with HYSYS Dynamics. This integration provides a unique tool to the world of advanced control. Configuring an Advanced Control mechanism typically requires step tests to be performed on the physical plant. These step tests take the plant off production until the APC model is configured. These costly step tests can now be eliminated by using a Dynamic HYSYS model instead of the plant to configure the DMC+ controller. See our website at www.aspentech.com for more information on Aspen's DMCPlus solution.

##### Upstream Option

AspenTech is excited to deliver the first phase of HYSYS Upstream with the release of HYSYS 3.2. The purpose of HYSYS Upstream is to extend the upstream capabilities of the HYSYS simulation enviroment. These improvement 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 also delivers mechanisms for integrating with production field models built in PIPESIM, an industry leading well and flowline modeling tool from Schlumberger. Using HYSYS Upstream 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.

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 behaviour 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.

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.

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.

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. It is 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.

PVT Integration

- InfoChem's Multiflash product is available with the HYSYS Upstream Option. Lab data from PVT analyses is entered into Multiflash in order to characterize reservoir and production fluids. This fluid characterization is then imported into HYSYS via COMThermo. Once inside HYSYS the user can choose to use the generated components with a HYSYS EOS or the Multiflash package for thermodynamic calculations. Look for InfoChem's Multiflash in the list of available fluid packages in the Basis environment.

PIPESIM Link The link to Schlumberger's PIPESIM, a single branch well and flowline modeling tool has been updated. Previously the link was made available for PIPESIM 2000. This link has been enhanced and upgraded to work with PIPESIM 2003. Using PIPESIM together with HYSYS, users can integrate models of petroleum wells with compressor station or facility models. PIPESIM-NET Operation

- A complete asset model of an oil and gas field can provide a powerful tool for planning and improving production activities. A new operation for imbedding Schlumberger's PIPESIM-Net within HYSYS has now been delivered. PIPESIM-Net can model multiple petroleum wells and complex gathering systems that make up oil & gas assets on and offshore. Combining these models with the onshore facility or topsides model with in HYSYS gives a holistic picture of the production field. Holistic approaches to production optimization, planning and sensitivity analysis has shown to significantly mprove the return on capital employed. PIPESIM 2003 models can be combined with HYSYS models through this new operation.

##### Engineering Enhancements - Steady State

Data Reconciliation Solver

- A new Data Reconciliation utility and solver has been added to the HYSYS environment. This new optional add on uses a solver from the well respected Harwell Subroutine Library. In online applications involving simulation models, real plant data input is loaded into the process model. Actual plant data inherently contains many errors in measurement. The inputs are accepted in the model and the flowsheet converges to an initial solution. Key calculated variables are then compared to actual plant data. An optimization algorithm is then applied to manipulate the input variables until the difference between the actual plant data and the model calculated variables is minimized. Data Reconciliation is a necessary step in Performance monitoring and Optimization applications involving actual plant data.

RVP Property Correlations

- Added RVP property calculations to the Stream Correlations. 2 of the industry standard API and 4 of the ASTM methods for calculating Reid Vapour Pressures are supported.

TACITE

- The TACITE correlation from Institut Petrole Francais for two phase flow in pipelines is available in the HYSYS pipe unit operation.

Heat Curve Points

- Added more property calculations to the Heat Curve points in the Heat Exchanger.

Electrolytes

- Redox reactions are now supported in the HYSYS Electrolytes OLI package. HYSYS 3.2 also marks a change in the licensing and security of the HYSYS Electrolytes OLI option. At this release and for future releases, AspenTech will only provide the HYSYS Electrolytes Interface. The Electrolytes physical property databases and calculation engines will be provided by OLI Systems Inc. The interface and engine will be secured separately by AspenTech and OLI Systems respectively. Stand Alone and Network installations will be supported.

Depressuring Enhancements

- There have been many improvements to the depressuring utility. The Summary page has many new options for displaying results. The Peak loading for the Vapour and the Liquid can easily be viewed. Tables of Cv/Final Pressure can be generated.

Stream Description

- On the Notes page of the stream you can now enter a descriptive text string about a stream that can be made to appear in the PFD. Press Shift + R to display the description in the PFD.

Compressor Curves

- Multiple Molecular Weight Curves can now be used to model more complex compressors that need to handle different compositions of gas. The multiple curves are added on the Rating page of the compressor and are used in Steady State and Dynamics.

##### Engineering Enhancements - Dynamics

Real Separator

- The Separator was enhanced in version 3.1 to behave as a non-equilibrium separator. Using the carry over parameters on the Rating page the separator could be set up to exhibit carry over or correlations could be used to calculate carry over. This capability is now supported in Dynamics mode.

Event Scheduler

- The user interface of the Event Scheduler has been improved dramatically. Sequences and Events are displayed in a graphical tree view complete with many different status icons. User's can now intuitively see the chain of events and follow them as they occur in the simulation.

Cause & Effect Matrix

- A graphical tool for visualizing and examining cause and effect logic. This tool can be used to design and monitor emergency shutdown logic in your dynamics simulations.

Profiling Tool

- The Profiling tool is a diagnostic tool for analyzing the performance of a dynamic simulation. The tool records the CPU time consumed by each unit operation while the integrator is running. The Unit operations can be sorted according to CPU consumption in order to identify the most time intensive units. This allows the modeler to identify areas of the model to focus on if model speed improvements are required.

COMThermo Support

- COMThermo packages are now supported in Dynamics mode.

Orifice Types

- Standard Orifice types are available in the Relief Valve. 14 standard orifice types from type D to T can be selected on the Relief Valve rating page and the appropriate orifice area will be retrieved from the database.

Vessel Emulsions

- A new approach for modeling emulsions in separators has been developed. An Emulsions fraction calculator option is available on the Dynamics page of the separator. This option assumes that when two liquid phases occur in the separator they will form an emulsion, thus both phases will appear in the liquid outlet.

Tray Rating

- New flexibility in the column tray section allows heterogeneous tray internals. Each tray section can be a different type of tray internal. Valve, Bubble and Sieve trays can be combined in a single tray section. Additionally, Sump and Chimney trays are now available as options for tray internals.

Trace Messaging

- New options in the preferences allow more control over the errors and warnings reported in Dynamics.

##### Other new Capabilities

HYSYS Browser - Link to Excel

- The HYSYS Browser is an add on to Excel that allows you to easily import and export data to and from Excel. This tool for linking with Excel requires no programming with VBA. Users can create powerful spreadsheets together with HYSYS to perform custom calculations or reports. This tool can be downloaded from the Support Knowledge Base.

  Alternatively, you can follow the steps below:

  1. Goto support.aspentech.com
  2. Click on "Knowledge Base" link, then Login using your username and password.
  3. Select "Hyprotech Products" from the "Family" drop down list.
  4. Select "HYSYS" from the product drop down list.
  5. Under the "Browse" frame, select "Sample Macros and Extensions" from the "Solution Types" drop down list.
  6. Click the "Browse by Topic" button.
  7. From the returned browse results, select "Sample Macros and Extensions" the select "HYSYS and Microsoft".
  8. Click on the document titled "Export Excel Data to HYSYS (the HYSYS Browser)"

Rotating Equipment - Inertia and Friction Loss

- There have been some corrections and enhancements to the modelling of inertia and friction loss for HYSYS rotating equipment in Dynamics. The pump, compressor and expander have all been updated to allow the user to select either of
  1. a first order time constant for acceleration/deceleration in the absence of flow or
  2. the friction loss factor (which now has a new definiition and units). For complete details of these changes and further explanation of how the energy balance is modelled, see the Dynamic Modelling section 1.6.4 of the HYSYS User documenation. When loading cases built in older releases of HYSYS and to preserve the same non-transient and transient behaviour as before, some of the values, particularily the inertia, will be modified upon recall. This ensures backward compatibility. The user is advised to check these values to ensure they are consistent with what is now desired.

Print PFD in SVG format

- The PFD can be exported in SVG file format. In the PFD, right click and select "Print PFD to File". Then select the SVG file format. SVG is a web friendly file format that allows the PFD to be displayed in a web browser and other applications.

Neural Net Improvements

- The training algorithm for the Neural Net has been improved. The new algorithm reduces the time it takes to train a Parametric utility. The interface has also been improved for ease of use.

Clean Fuels Extension Property Package.

- With new strict global-wide legislation regulating undesirable emissions from internal combustion engines, refineries are facing challenging design decisions to meet lower sulphur targets in motor gasoline. With these regulations continuing to evolve, reducing sulphur to target levels will likely involve some of the highest capital costs for refiners. The Clean Fuels Property Package is a specially designed property package for the accurate VLE representation of thiol-hydrocarbon containing systems. The Clean Fuels Pkg contains the latest advances made in the development of cubic equations of state and mixing rules. A new vapor pressure alpha function is available that is correlated against DIPPR vapor pressure data as well as DIPPR pure component properties for 1454 HYSYS components. For more information refer to the Clean Fuels PPkg User Guide that is installed with the extension.

##### 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.

##### PIPESYS v2.0

The HYSYS 3.2 CD also contains a new version of PIPESYS. Version 2.01 build 67 has these new capabilities and enhancements:

1. The Erosion Velocity check calculation was changed so that no maximum erosion velocity is computed for a single phase liquid or single phase gas fluid when there is no sand production. Single phase liquid, single phase gas and multiphase fluids do compute both the maximum sand free and with sand erosion velocities.
2. A problem was encountered that under certain circumstances would cause the Beggs and Brill liquid holdup correlation to predict a liquid volume fraction greater than one causing the calculations to fail. This has now been corrected.
3. A problem exited with the reverse pressure calculation in PIPESYS that caused the incorrect flow rate to be used for the feed stream after the pressure estimate is done when side streams exist in the profile. This has been corrected.
4. The reference to pipe types has been removed from the list of available external coatings types at the request of Hyprotech's support staff.

####

Rectified Issues

4. The compositions on the Compositions page of the Workbook can now be properly displayed by selecting the choices for different fluid package.
5. Implicit Check valve
6. The Esso Tabular property package now works properly under COMThermo.
7. The BIPs for Water and Ethanol were improved to better represent the VLE of these systems.
8. Dynamic initialzation has been improved to be able to manipulate groups of objects in order to better support large places.
9. Solid components are now properly handled in Dynamics.

####

Known Issues

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

1. Property Package Extensions - Your custom property package extensions MUST be recompiled against the HYSYS 3.2 Type Library to ensure that they properly function with version 3.2 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 v3.2
2. 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.
3. Black Oils: The Black Oils package is not supported in Dynamics
4. PIPESIM 2003 links: The new links to PIPESIM and PIPESIM-Net are designed to work with the PIPESIM 2003 version.
5. PIPESIM 2003 links: These links only support Compositional mode inside PIPESIM 2003.
6. Solid Unit Operations are not supported in Dynamics.
7. Tool Tips: If HYSYS 3.2 is started for the first time after installation and a users 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.
8. MSXML Parser - During the installation of HYSYS 3.2, 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.
9. XML - Extension Property Packages, Extension Unit Operations and User Variables are currently not supported by the XML file input/output systems.
10. XML - Not all calculated data is available in the xml output file.
11. 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.
12. 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.
13. Security - Infrared ports setup for PDA devices may interfere with SLM keys.
14. 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.

Upgrade/Release Package

Your package may include:

- 1 Get Started Manual
- 1 Software CD (Inside back cover of the Get Started manual)
- 1 Documentation CD (Inside back cover of the Get Started manual)
- 3.5" Floppy disk with license file/s (Inside back cover of the Get Started manual)

If you are a new HYSYS customer or upgrading network licensing from version 2.2 and lower then your release/upgrade package will also include:

- SLM hardware key(s)

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 3.1 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 Get Started manual.

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 Get Started manual for Upgrading Your Network Security instructions before installing HYSYS.

New HYSYS 3.2 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 Get Started manual. To install HYSYS, refer to section 1.4 in the same manual.

###

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.

###

SLM Security System FAQ

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 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. It is also possible to add these files later by following the instructions in the Get Started manual.

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 Get Started manual. Please install the license file as outlined in the Get Started manual.

5. 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, Technical 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 Hyprotech 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.

6. 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.

7. 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 Get Started manual.

###
