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.
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 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.
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.
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.
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.
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.
PVT
characterizations performed in Calsep’s PVTSim package can be imported into
HYSYS’s PVT environment. (See above).
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.
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.
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.
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.
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.
There have been
many improvements to the depressuring utility.
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.
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.
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.
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.
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.
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.
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 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.
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.
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.
Under surge
control parameters you can now make use of a higher order polynomial to
calculate the surge flow from the head.
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.
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.
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.
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
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.

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.

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.

detailed installation instructions refer to the Installation Guide available via
the CD browser HYSYS Documentation
option.
Upgrade/Release Package
Your package
may include:
·
1 Software CD
·
Installation Guide and HYSYS documentation (included on the application
CD in PDF format and available from the CD Browser)
·
3.5” Floppy disk with license file/s
If you are a
new HYSYS customer your release/upgrade package will also include:
·
SLM
hardware key/s
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.
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.
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.
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 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.
