Aspen Multi-Case

Aspen Multi-Case is a new product that provides multi-core and high-performance computing capabilities for Aspen HYSYS and Aspen Plus, allowing you to run multiple simulations simultaneously and visualize results. Aspen Multi-Case serves as a single platform that allows you to seamlessly transition between setting up cases, configuring runs, concurrently running simulations, and analyzing results. By leveraging the parallelization capabilities for Aspen HYSYS and Aspen Plus, Aspen Multi-Case enables you to run a large number of simulations quickly and easily.

You can create projects that are associated with HYSYS and Aspen Plus case files ("base cases") and define scenarios for comparison and visualization. The project types available in Aspen Multi-Case support the following key workflows:

Case Study projects offer an improved version of the HYSYS Case Study / Aspen Plus Sensitivity Analysis due to easier configuration and high-performance computing.
Multi-File Analysis projects support multiple files and flowsheet topologies in order to help you analyze multiple design configurations and operating conditions for a large number of scenarios.
Reduced Order Model projects allow you to generate data that can be used in the AI Model Builder.
Aspen Multi-Case offers the following benefits:

Seamless case configuration without the need to open Aspen Plus or Aspen HYSYS.
Provides advanced data analysis and visualization capabilities.
Allows analysis of complex design problems involving multiple files and flowsheet topologies.
Results in an improved simulation workflow when optimizing across several design scenarios.
Eliminates the need to transfer data to Excel for analysis and visualization.
Aspen Multi-Case supports distributed deployment, enabling you to leverage multi-core machines on-premises or in the cloud and run the simulations in parallel. For multi-user machines (such as Windows Server), Aspen Multi-Case allows multiple users to work on the same machine and ensures that other users are prevented from editing your projects.

Interactive visualization helps you analyze results and analyze results across multiple cases. Results visualization options include plots (both two-dimensional and three-dimensional), tables (including aggregation and filtering capabilities), and matrices.

For further information regarding Aspen Multi-Case, see the Aspen Multi-Case Help.

You can create an Aspen Multi-Case project linked to your current simulator case from within Aspen HYSYS and Aspen Plus. To do so, on the Home ribbon tab | Multi-Case group, click Project. A new Aspen Multi-Case project is automatically created and appears in your web browser. The new Aspen Multi-Case project will be a Case Study project with the current simulator case attached as a base case. See Creating an Aspen Multi-Case Project.

Aspen Knowledge In-Context

Aspen Plus V12 features Aspen Knowledge In-Context, which delivers curated, featured content that is seamlessly integrated within the Aspen Plus flowsheet. This tool allows you to access relevant Aspen Knowledge material within Aspen Plus, providing relevant information that reflects your specific flowsheet topology and interactions with the process model. For example, content regarding Aspen Exchanger Design & Rating appears when you are working with an Activated Heat Exchanger. As a result, you can easily obtain the information needed to complete your current workflow.

You can access targeted information from our database, including literature, training, eLearning content, Knowledge Base articles, content from the HTFS Research Network, and videos.

Aspen Knowledge In-Context provides the following benefits:

Aids you in solving complex asset optimization challenges in an easy-to-use interface.
Facilitates improved search and discovery and successful knowledge delivery.
Makes it easier for you to locate the necessary information to troubleshoot convergence or modeling errors.
Provides best practices guidance and model building assistance.
Provides convenient access to eLearning content.
Allows you to share feedback with AspenTech to facilitate improved content delivery.
The icon is used to indicate that Aspen Knowledge In-Context recommendations are available for the current Aspen Plus form. Aspen Knowledge In-Context recommendations are available for forms with context-sensitive help within Aspen HYSYS and Aspen Plus.

Plant Data

Plant Data now includes seamless transition with Aspen OnLine, including an option to publish a model originally developed in Plant Data to Aspen OnLine. If you open the model file from Aspen OnLine's Offline or Online folder, you can make changes within Plant Data which are stored in the Aspen OnLine project. You can also edit features, such as scheduling, which are only relevant when the project is open in Aspen OnLine. You can perform Offline-to-Online within Plant Data and, if there are no model changes, use the variable list in Aspen OnLine without having to regenerate it.

Data Conditioning includes new features for identifying data to exclude from runs. You can mark slices manually as bad, or mark a pattern as bad and let AI methods mark all similar slices as bad. Outlier detection helps identify data sets as outliers that you want to exclude. And smart sampling lets you pick a representative sample of the data to run if you have too many cases to run all of them.

Pre-Averaged Data Mode allows you to work more simply with data that has already been averaged. This mode works only with a single data import from Excel or a historian of a set of data points which are equally spaced in time. For more information, see Pre-Averaged Data Mode.

Many grids in Plant Data now have filtering options similar to those in other Aspen Plus and Aspen HYSYS forms. You can filter the items displayed in the grid by the contents of any column. Time ranges can be filtered to a specific interval. In some tables you can customize the columns displayed with the Table Layouts feature.

When you create model snapshots, the default names are now based on the run sequence names. This makes it easier to identify which snapshot comes from which run sequence.

General Usability Improvements

The plot configuration for parity plots (such as Estimated vs. Experimental) has been re-ordered. Now you pick the variable first, and then the data groups to plot from a list which only includes data groups containing that variable. This lets you generate parity plots with multiple data groups, using a different symbol for each group.

Plots you create in BatchSep can now be saved under the Plots folder of the BatchSep block and restored from this form and edited in ways already available for batch flowsheet plots. This only applies to new plots created in version V12; plots created in earlier versions cannot be saved in this way.

In custom reaction kinetics, many new variables are available, mainly specialized ones which require specific types of reactor, stream, or phase, such as number average and volume average particle diameter (based on particle size distribution) and the time (in batch reactors). Property sets are also available. These variables support the specification of rates for heterogeneous catalyst reactions, reactions involving electrolytes, mass-transfer-limited reactions, decay equations, calculations of ratios like flow/holdup which may allow scaling rules, and reactions involving polymer and non-conventional components.

In BatchOp, when you calculate pressure and specify the volume, you can now specify the pot geometry rather than specifying the volume directly. The options include horizontal and vertical vessels and various head types as in BatchSep.

More blocks now have animated flowsheet diagrams. These include:

BatchOp, on the Setup | Specifications sheet
You can pause the run during the integration step of a BatchSep block using a Pause button on that BatchSep block's animated diagram. During the pause, you can examine results (including the Time Profiles of the BatchSep block) but you cannot edit input or interact with most other controls. You can stop the entire flowsheet run from the ribbon or resume the run from the BatchSep animated diagram.

When you export binary data sets from TDE to Data Set forms, Aspen Plus now writes a description into the Data Set describing the components and range of data, similar to what was already done for pure component data sets.

The Regression | Input | Setup sheet now has a Run button that lets you run just that regression. The Regression | Results | Parameters sheet now has an Update Parameters button that lets you copy results from regressions to parameter input forms if you have not selected the option to automatically copy them. The Setup sheet also has an option to run an analysis using the regression results immediately after finishing the regression, and the plot wizard can plot these analysis results. This allows you to quickly detect inconsistencies between the model conditions and regression conditions which might lead to poor fits.

The Pitzer electrolyte ternary parameters GMPTPS, GMPTP1, GMPTP2, GMPTP3, and GMPTP4 have been converted into electrolyte pair parameters. This allows them to be stored in the Aspen Properties Enterprise Database. No such parameters are in the delivered database, but if you make a custom database with a PITZER databank containing these parameters, the model can now use them without you defining them in every model. Instead of using the Electrolyte Ternary form to enter the parameters, you now enter them on the Electrolyte Pair form. When you load files with data for these parameters from past versions, they will automatically be converted to use the new format. These changes do not affect model results. For more information, including instructions for building a custom databank with Pitzer parameters entered into your simulations, see the help for the Pitzer model.

In the Find Compounds dialog box, you can now search for compounds by CAS number if you enter digits and a hyphen (to match at least one whole section of the number).

Engineering Improvements

Aspen Plus can now make use of hybrid equipment and sensor models created in Aspen AI Model Builder. These models are installed on your computer in the same way as exported ACM models and become available in the Hybrid Models and Hybrid Sensors tabs of the Model Palette.

Custom reaction kinetics in a General reaction set is now supported in equation-oriented (EO) modeling, in the reactors RCSTR and RPlug. All custom kinetics variables from V11 are supported, as are true component concentration and pH (when the block is in true approach), mass/molar/volume flowrate and volume holdup (for liquid and vapor phase only), active cross-sectional area for RPlug, and catalyst mass. No solid phase variables are supported. Reactors using unsupported custom variables will run in the perturbation layer.

Reaction kinetics are now reported in individual RCSTR, RPlug, RBatch, and BatchOp blocks. An option in the Block Options form of each block controls whether this report is generated. The reports include rates and the terms in the rate expression for power law, LHHW, and general reactions, and the variables and terms of custom reactions.

Crystallization reactions now include an option to model the kinetics of agglomeration of crystals. The crystal agglomeration model uses the same general form and size-dependent kernels as the mixed agglomeration model from the Granulator block, but uses a time-dependent kernel specific to crystallization.

You can now connect Aspen Plus heat streams to energy ports of CAPE-OPEN unit operation models. The duty of an inlet heat stream is provided to the block as an input. The duty of an outlet heat stream is set by the block.

When you specify pad gas for the initial contents of an initially empty BatchOp block, you can now specify the initial temperature of the pad gas. This allows the pad gas option to be used when the vessel is initially empty. When there is some charge but pad gas is added to a specified pressure, the pad gas has the same temperature as the initial charge, as in past versions.

In addition to the other types of fittings, you can now specify globe valves in Pipe.

A new packing correlation from Sulzer is included in V12. This includes new packing types, materials, and dimensions:

NexRing #0.6, #0.7, #1, #1.2, #1.5, #2, #3 (new type and dimensions)

AYPlus DC standard (new type and dimension)

CYPlus standard (new type and dimension)

MellapakPlus 202.Y 352.Y 602.Y (new dimensions only)

Mellagrid 40AF (new dimensions only)

Mellapak plastic 125X (new material and dimensions)

MellapakPlus plastic 252.Y (new material and dimensions)

Other previously available Sulzer packings are also supported by the new correlation, except I-Ring, Kerapak, and Nutter ring #1.75. The old correlation will be used for those. When you open a file from earlier versions which contains a Sulzer packing supported by the new correlation, you will be prompted whether to upgrade to the new correlation.

Starting in V12 RadFrac can compute load streams in problems configured for two liquid phases (including free-water and dirty-water).

It's now possible to use version 7 of SPYRO from Technip, with both Kinetic Scheme KS9306 and 7, in Aspen Plus. If you were previously using version 6, some changes in the configuration file are necessary. For details, see Using SPYRO.

Physical Property Improvements

The Copolymer PC-SAFT and Cubic-Plus-Association models were updated to include terms for cross-association and solvation, including self-association. This includes the new parameters PCSEIJ, PCSVIJ, and PCSAIJ for PC-SAFT and parameters CPAEIJ, CPAVIJ, and CPAAIJ for CPA. For more information, see Copolymer PC-SAFT EOS Model Parameters and Cubic-Plus-Association.

HCOMB is a new property-set property for the heat of combustion of nonconventional components.

You can now click BIP Completeness on the parameter input sheets for binary interaction T-dependent parameters to see a grid displaying the completeness of binary interaction parameters entered on that sheet. The components are listed in rows and columns, and for each pair of parameters, a white cell indicates there is no data, and a colored cell and a single-letter abbreviation indicates the source of data in use for that parameter. See the help on these sheets for the key identifying the source types.

In data regressions, a new plot of deviation of any property vs. temperature is now available.

In pure component analysis, a new equation-of-state alpha function test is available. This lets you confirm the parameters for your alpha function (for one of the Peng-Robinson or Redlich-Kwong-Soave variations which support alpha functions) are thermodynamically consistent over the temperature range of interest. For more information, see Pure Component Properties.

Ternary data is now available from NIST TDE and can be added to Data forms in your project. Other updates from NIST include a new database version with updated data and 512 new compounds, and an updated version of REFPROP.

In Aspen Properties Database Manager, there is new a command which streamlines the process for switching from LocalDB to a SQL server on the local computer. See Configuring Windows to Not Use LocalDB for details. There is also now a For cloud deployment checkbox available when registering databases on a SQL server on the local computer which stores the database name as localhost rather than the computer name. This makes the local configuration suitable for use as a base image for a cloud deployment.

You can now export assays characterized in Aspen Assay Management to input (.inp) files which can be opened within Aspen Plus. The generated input files are compatible with Aspen Plus V10 and later versions. When you open the exported .inp file in Aspen Plus, the following information is specified within the Assay/Blend object manager in the Properties environment based on your specifications in Aspen Assay Management:

Distillation yield curve data (on the Basic Data | Dist Curve sheet)
Property curve data (on the Property Curves form)
The PURE38 databank is based on the 2019 public DIPPR release. The DIPPR compounds in the database are the same ones as in PURE37, but these additional heating fluids have been added:

Alias Name
THERM59 Therminol 59
THERM62 Therminol 62
THERM72 Therminol 72
THERM75 Therminol 75
THERMD12 Therminol D-12
THERMLT Therminol LT
THERMVLT Therminol VLT
THERMVP3 Therminol VP-3
THERMXP Therminol XP
In addition, the data for Therminol 55 (THERM55) and Therminol VP-1 (THERMVP1) has been updated based on the latest Eastman Chemical technical bulletins.

Safety Analysis Improvements

Improved Datasheets Workflow

The workflow for creating ABE datasheets in order to document PRD calculations has been improved and streamlined in Aspen Plus V12, including the following changes:

The new Safety Datasheets ribbon tab makes necessary commands more easily accessible (such as connecting to a workspace or closing the connection).
You can use the new Live Link option to automatically transfer all data for mapped objects to Aspen Basic. Changes in the simulation are automatically transferred to applicable datasheets. As a result, you no longer need to return to the Mapper view and click Refresh to transfer data.
When the Live Link is option is selected, you can use the contextual Datasheet button to view or create datasheets related to the Safety form. When you click the Datasheet button, a drop-down appears, displaying relevant Safety datasheet templates based on the current form and Safety calculations. This list includes both existing datasheets and those available for creation. This option eliminates the need to perform mapping if you only need to document a single system or calculation.
Fire Disengagement Calculations

Optionally, you can enable prediction of two-phase relief flow for Wetted (API) fire scenarios using the Calculate Vapor/Liquid Disengagement drop-down list. Vapor/liquid disengagement is calculated using DIERS methods to predict whether a period of two-phase relief will occur. Aspen Plus predicts the initial liquid level at which two-phase flow begins and ends, as well as the required orifice area needed for adequate protection during the period where two-phase flow occurs.

Support for API 520 Part 1 10e (2020) for Sizing Calculations

The Safety Preferences Manager now allows you to select API 520 Part 1 10e (2020) as the API 520 Part 1 Edition for Sizing Calculations. The 10th edition includes updates to the liquid viscosity correction factor equation and steam superheat correction factor tables. As a result, selecting this option leads to differences in results for the Capacity-Certified Liquid, Non-Capacity-Certified Liquid, and Steam relieving methods.

Ability to Perform Line Sizing Calculations for Non-Sizing Cases

Previously, line sizing calculations were only performed for the scenario designated as the Sizing Case on the Scenarios tab.

In V12, the Current Scenario drop-down list on the Line Sizing tab allows you to select the desired scenario, and then click Run Line Sizing to perform line sizing calculations. The Run For All Scenarios button performs line sizing calculations for all specified scenarios.

Safety Analysis Enhancements

Hydraulics Tee calculations are fully supported. The settings specified in the Tee Settings group on the Calculation Settings view are now applied correctly. Static Pressure, Total Pressure Balance, Miller Charts, Gardel, and Simple fitting loss methods are available. Additionally, the Fixed k value option allows you to use the V11 method, where Tees are implemented as a combination of a bleed and flow resistance.
The maximum Number of Vessels for Unwetted (API) and Wetted (API) Fire scenarios was increased from 3 to 9.
The Molecular Weight and Compressibility Factor Z values are now reported in the Relieving Properties group of the Fluid Properties tab.
The new Relief Composition tab allows you to view the relief composition for relieving load calculations for the scenario. It contains a table that lists the fraction represented by each component from the selected component list.
For the Semi-Dynamic Flash calculation method, when you select the Store per-step compositions for semi-dynamic fire calculations check box on the Scenarios tab of the Preferences Manager, a new tab on the Stepwise Flash Data dialog box displays the stream composition on a step-by-step basis. A column appears for each component in the stream. The row selected for relief is highlighted in the composition table.
