Sustainability
Greenhouse Gas Emissions
There is a new Greenhouse Gas Emissions panel on the activation dashboard. Reporting for greenhouse gas emissions uses industry standard terms scope 1 (process emissions) and scope 2 (fuel emissions).
The IPCC's AR6 is now supported as the standard for scope 1 emissions. The U.S. EPA standard for scope 2 emissions is updated to US - EPA Title 40.
On the Process CO2 Emissions tab of the Flowsheet Summary, IFPP has been changed to IPCC (Intergovernmental Panel on Climate Change).
Additional Support for CO2 Emissions Added in Process Utilities Manager
In the Process Utilities Manager, two additional columns have been added. These columns are Scope and CO2 Adjustment Factor. Scope lets you specify whether the particular utility contributes to Scope 1 or Scope 2 CO2 emissions (this will also be reflected in the Utility Summary tab of the Flowsheet Summary). CO2 Adjustment Factor lets you add an adjustment factor (multiplier) to the carbon emission calculation.
The Fuel EF (fuel efficiency factor) column now also lets you specify negative values to discount CO2 emissions from the utility.
New Hydrogen Economy Examples
Five new sustainability related example files dealing with Hydrogen economy have been added to the Aspen HYSYS V14.0 | Samples | Sustainability | Hydrogen Economy folder (new). The example files are:
Alternative cascade mixed refrigerant (CMR+) precooling.hsc - This example models the alternative Cascade Mixed Refrigerant (CMR+) precooling process in large-scale hydrogen liquefaction plants.
Alternative single mixed refrigerant (SMR+) PRICO precooling.hsc - This example models the single mixed refrigerant (SMR) PRICO+ precooling process in large-scale hydrogen liquefaction plants
Cascade mixed refrigerant (CMR) precooling.hsc - This example models the Cascade Mixed Refrigerant (CMR) precooling process in large-scale hydrogen liquefaction plants
H2 cryogenic process.hsc - This example models the integrated cryogenic process in large-scale hydrogen liquefaction plants.
Single mixed refrigerant (SMR) PRICO precooling.hsc - This example models the single mixed refrigerant (SMR) PRICO precooling process in large-scale hydrogen liquefaction plants
Ortho-para hydrogen conversion is modeled using the new Aspen HYSYS Hydrogen Property Package. All of these examples can be used as a starting point for more complex models for process design and optimization, debottlenecking, and plant and equipment design.
New Carbon Capture Example
A new example case called CO2 Capture Using K2CO3.hsc has been added to the Aspen HYSYS V14.0 | Samples | Sustainability | Carbon Capture folder. The example case models CO2 capture at the rate of ~50,000 tons per year by using K2CO3. This example can be used as a starting point for more complex models for process design and optimization, debottlenecking, and plant and equipment design.
New Alkaline Electrolysis Examples
Two new sustainability related example files dealing with Alkaline Electrolysis have been added to the Aspen HYSYS V14.0 | Samples | Sustainability | Alkaline Electrolysis folder (new). The example files are:
Green Ammonia Process.hsc - Ammonia synthesis process that uses a built-in shortcut Electrolyzer for Hydrogen production.
Industrial Scale Alkaline Electrolysis Plant.hsc - Models an industrial scale electrolyzer using the new built-in electrolyzer model in Aspen HYSYS V14.
Accompanying word documents describing both example cases can be found in the Aspen HYSYS V14.0 | Samples | Sustainability | Alkaline Electrolysis folder.
New Sustainable Refining Examples
Seven new examples dealing with sustainable refining (bio fuel and sustainable feeds to chemicals) processes have been added to the Aspen HYSYS V14.0 | Samples | Refining Cases folder. The example files are:
Heavy_Aromatics_Transalkylation_Example.hsc - This example case models transalkylation of heavy aromatics to xylene isomers using an Aromatic Production Bed.
Hydroconversion_of_Soybean_to_Hydrocarbons_Example.hsc - This example case models hydroconversion of soybean to hydrocarbons.
MBRXRBed_COFeed_ARM_Example_Case.hsc - This example case models a hydroprocessing bed with a HDO/HCR co-feed.
Production_of_Green_Diesel_with_Waste_Cooking_Oil_Example.hsc - This example case models the conversion from waste cooking oil to green diesel using a HDO Bed.
Simulation_of_Aromatics_Complex_Example.hsc - In this example case, a naphtha stream is catalytic reformed by a CCR. The products are separated into two parts. The first part mainly contains toluene, which undergoes the toluene disproportionation process to obtain xylene isomers. The second part mainly contains C9 aromatics; the C9 aromatics then undergo transalkylation reactions to generate xylene isomers. The xylene isomers then isomerize to obtain more valuable p-xylene.
Simulation_of_Aromatics_Complex_Example_AspenPlus_Extractor.hsc - Similar to the aforementioned case, but contains a MB Model Container with an Aspen Plus model connected to it.
Toluene_Disproportionation_Example.hsc - This example case models disproportionation of toluene to xylene isomers using an Aromatic Production Bed.
Accompanying PDF documents describing the example cases in greater detail can be found in the Aspen HYSYS V14.0 | Samples | Refining Cases folder.
Biofeed Processing
Aspen HYSYS V14 includes two new reactor templates within the Aspen HYSYS MB Reactor unit operation to facilitate bio-feed processing in HYSYS.
HDO Bed (hydrodeoxygenation) reactor is now available. This will enable you to model bio-feed conversion to hydrocarbons.
Co Feed Hydroprocessing Bed - A Co Feed model template has been added to the Hydroprocessing Bed Model Type. This is a combination of a HDO Bed and a Hydroprocessing Bed, which will enable the modeling of hydrotreating for a mixture of bio-feed and hydrocarbon feed.
Electrochemistry
Power Stream
Aspen HYSYS offers a new stream type for V14: the Power Stream. Power streams are energy streams that account for electrical power. Power streams can be used to model systems involving units such as electrolysis cells, since these streams account for parasitic energy demand in which some of the generated power is used to drive motors to compress hydrogen, oxygen, and/or air and to circulate fluids for cooling or renewal of the cell.
Electrolyzer Unit Operation Model
A new Electrolyzer unit operation has been added in Aspen HYSYS V14. The Electrolyzer can be used to represent an electrolytic stack or module (includes the stack, gas separators and recycle streams) performing electrolysis to generate hydrogen and oxygen from water. The Electrolyzer models the Alkaline Water Electrolysis process. Simple (shortcut) and rigorous electrolytic stack modeling options are available, as well as a simple electrolyzer module modeling option.
To accommodate the new Electrolyzer unit operation, the following additional physical type variables are available in Aspen HYSYS V14:
Physical Type
Available Units
Amperage A, mA
Current Density A/m2, A/cm2, mA/m2, mA/cm2, A/ft2
Electric Field Strength V/m, V/km, V/ft
Electrical Resistance Ohm, mOhm, kOhm, microOhm
Electrical Resistivity Ohm-m, mOhm-m, kOhm-m, uOhm-m, Ohm-ft
Faraday Constant C/mol, C/kmol, C/lbmol
Power Density W/m3, W/km3, W/ft3
Two example cases that use the Electrolyzer unit operation have been added to V14. These can be found under the Samples\Sustainability\Alkaline Electrolysis folder. The example cases are:
Green Ammonia Process.hsc
Industrial Scale Alkaline Electrolysis Plant.hsc
General Aspen HYSYS Improvements
New Nonstoichiometric Reactor Unit Operation
Aspen HYSYS V14 includes a new Nonstoichiometric Reactor (RYield) unit operation, which can be used for performing component yields and lumping or delumping components. It offers similar functionality to the RYield block in Aspen Plus.
You can use the Nonstoichiometric Reactor to model a reactor when:
Reaction stoichiometry is unknown or unimportant.
Reaction kinetics are unknown or unimportant.
Yield distribution is known.
You want to minimize non-zero components to ensure faster performance.
You want to normalize yields to maintain a mass balance.
You want to manipulate component mapping or component yields using a single fluid package, without requiring a Stream Cutter (which requires two different fluid packages).
The Nonstoichiometric Reactor can model one-phase, two-phase, and three-phase reactors.
Ortho-Para Hydrogen Equilibrium Reaction
Starting in V14, a new Ortho-Para Hydrogen Equilibrium reaction is available from the library. This predefined reaction uses the Bliesner model (Bliesner, R. M. Parahydrogen-orthohydrogen conversion for boil-off reduction from space stage fuel systems. Thesis for Masters of Science in Mechanical Engineering, Washington State University, 2013.).
Line Sizing Manager Improvements
In V14, the Line Sizing Manager can handle single component and multi-component fluids and close-to-bubble point conditions. You can also now use the Line Sizing Manager to size compressible gas flow lines.
Check for Updates Using the aspenONE Update Agent
Clicking aspenONE Update Agent on the Resources ribbon now opens the aspenONE Update Agent to check for updated versions of Aspen HYSYS. The aspenONE Update Agent helps you download, install, and/or deploy available software updates (also known as "patches").
The Local Updates option allows you to install updates found locally on your machine.
The All Available Updates option allows you to install updates found locally on your machine and search for additional updates using your AspenTech Support Center credentials. The aspenONE Update Agent communicates with the AspenTech Support Center to retrieve updates. A service allows you to schedule the aspen ONE Update Agent to search for patches daily, weekly, or monthly (depending on your preference). The aspen ONE Update Agent helps you download and install updates from the Support Center.
The Unattended Deployments option is generally used by IT personnel. It allows you to silently deploy product updates.
For further details, see the aspenONE Update Agent Help.
Aspen E-learning Button Added
A new button was added to the Resources tab in HYSYS and Aspen Plus to provide direct access to the eLearning platform from the simulator. This will solve discoverability issues and enable users to quickly access to learning modules.
Improvements to Phase Handling for Correlation Properties
In V14, Improvements were made to how phases are handled for correlation properties (available via the Correlation Manager and the Worksheet tab | Properties page). In previous versions, phase results sometimes appeared incorrectly in the Spreadsheet operation and Aspen Simulation Workbook (ASW) after changes to the phases and/or number of phases occurred. In V14, results shown in the Spreadsheet operation and ASW remain consistent with the current stream properties and reflect any phase changes.
Improvement to Aspen AI Model Builder Integration
On the Home ribbon tab (simulation environment) an AI Model Builder button has been added, that allows you to launch Aspen AI Model Builder.
Activated Economics Integration with Aspen OptiPlant 3D Layout
A new button, Send to OptiPlant 3D, has been added to the HYSYS Economics ribbon. This allows you to export equipment data to an Excel file, once it has been mapped, sized, and evaluated. The Excel file can then be directly imported into Aspen OptiPlant 3D Layout, a 3D conceptual design tool.
Aspen HYSYS Properties Improvements
New Hydrogen Property Package
Aspen HYSYS V14 includes a new Hydrogen Package property package. The Aspen HYSYS Hydrogen Package enables you to model mixtures that contain hydrogen with ortho/para conversion. When modeling hydrogen with other components (such as light hydrocarbons other noble gases) in a multi-component mixture in mixed refrigerants, Aspen HYSYS thermodynamics calculations predict the equilibrium split between the two forms based on minimizing the energy state. In a system containing hydrogen at very low temperatures, you can use the package to model the cryogenic process of compressing and transporting hydrogen-related compounds.
Five example cases that use the Hydrogen Package have been added to V14. These can be found under the Samples\Sustainability\Hydrogen Economy folder. The example cases are:
Alternative cascade mixed refrigerant (CMR+) precooling.hsc
Alternative single mixed refrigerant (SMR+) PRICO precooling.hsc
Cascade mixed refrigerant (CMR) precooling.hsc
H2 cryogenic process.hsc
Single mixed refrigerant (SMR) PRICO precooling.hsc
MXBonnel Property Package
A new FCC Default option is available as the EOS Model for the MXBonnel property package.
Aspen HYSYS Dynamics Improvements
New Header Unit Operation
A new Header operation has been added in V14. The Header operation combines two or more inlet streams to produce two or more outlet streams. The Header operation is equivalent to the combination of the Mixer and Tee operations.
New CCC Link Operation
A new HYSYS-CCC Link unit operation was added in V14. This is an extension that can be used to create links between Aspen HYSYS and the Prodigy Emulator or Series 5 Emulator from Compressor Controls Corporation. Compressor Controls Corporation (CCC) emulators provide a transportable, cost-effective method to incorporate emulations of CCC control systems in plant-wide emulation models. Typical uses of the emulator include Operator Training Simulators (OTS), interfacing with plant simulation systems, engineering studies, control system testing, and pre-commissioning testing.
The controllers in Aspen HYSYS act as proxies of the actual controllers in the CCC Prodigy emulators. The communication occurs through the OPC server that comes with the emulator. The link requires an Aspen HYSYS Spreadsheet with the input/output variables that must be exchanged between the emulator and the Aspen HYSYS model. For any OPC variable name, the extension expects the name without the IP address or instance number.
Malfunction Scenarios Added to Compressor/Expander
Total Failure and Performance Deterioration malfunction scenarios can now be modeled in the Compressor/Expander operation. These work the same way as in the Pump operation. The Total Failure setting will cause a complete shut down for the Compressor/Expander. Performance Deterioration is used to simulate plant conditions involving performance loss due to fouling or suction loss.
PID Controller Step Testing
A new page called System Identification is available on the Parameters tab of the PID Controller operation. This page allows you to perform a step test and calculate the parameters for a first order model plus dead time model (FOPDT) – process gain, process time constant, and dead time). This information can be automatically transferred to the IMC Design page, where the control tuning parameters can be calculated.
Integration with Aspen Operator Training
The Dynamics ribbon tab in Aspen HYSYS now contains the following buttons:
Operator Training: Launches Aspen Operator Training (AOT), an application that provides an end-user environment for plant operators and training instructors where operators can be trained using a process model as a virtual plant without affecting actual plant operations.
Data Table: Opens the Data Tables view. Starting in V14, Aspen HYSYS allows you to quickly and easily prepare variables that you can use to build an operator training system in Aspen Operator Training (AOT) using the OTS Configuration Options group in the Data Table.
Aspen HYSYS Midstream Improvements
Lee-Kessler Enthalpy Calculation Available in CPA Property Package
In V14, Lee-Kessler is available as an Enthalpy calculation option for the CPA property package. The Lee-Kessler option may improve heat capacity calculations and provide results that more closely match experimental measurements in some simulations.
Improved Water Heat Capacity Predictions for Acid Gas Property Packages
In Aspen HYSYS V14, the pure water heat capacity predictions for the Acid Gas – Chemical Solvents property package were improved to ensure greater consistency with experimental data.
To improve water heat capacity, the water parameters for heat of vaporization (DHVL) were updated. In V14, the predicted water heat capacity accurately matches the experimental data (see Figure 1), and the prediction for heat of vaporization also match the data accurately (see Figure 2).
Figure 1: Water Liquid heat capacity. The points are the experimental data, and the curves are the predictions for the Acid Gas – Chemical Solvents property package. V12 represents the previous results, and V14 represents the new results.
Figure 2: Heat vaporization of water. The points are the data from IPAWS-95 Steam Tables, and the curves are the predictions of Acid Gas – Chemical Solvents property package. V12 represents the previous results, and V14 represents the new results.
Improved CO2 Absorption and Desorption for Acid Gas - Chemical Solvents Property Package
Prediction for CO2 absorption and desorption using the Acid Gas - Chemical Solvents property package was enhanced in V14 to better reflect field data. Using plant data from Sulphur Experts, the model for CO2 absorption and desorption was validated and improved.
Acid Gas ROM Improvements
A new ply has been added on the Parameters tab of the Column form, called ROM. This allows you to edit the Binary Scaling Factors, which affect the BIPs in the model. Enthalpy Scaling Factors can also be edited in Absorbers, and can be used to improve the temperature profile.
Note that this is only available for columns that use the Reduced Order Model option in the Property Package Model (previously named Enthalpy & Fugacity Models) drop-down list, on the Phase Handling tab of the Fluid Package property view (Acid Gas - Chemical Solvents property package only).
Added Support for the Benfield Process in Acid Gas
K2CO3 is now a supported chemical solvent in the Acid Gas – Chemical Solvents property package. Accordingly, the dissociation reaction of K2CO3 has been added into Reactions | Set-3.
A new sample case called Acid Gas Cleaning Using K2CO3 has been added into the Samples | Acid Gas Cleaning folder. This sample case models the Benfield Process, which uses K2CO3 as a chemical solvent.
MakeUp Unit Operation Enhancement: Circulate Electrolytes
In V14, the functionality for making up electrolytes in the MakeUp operation has been added. All Aspen Electrolyte Property packages are now supported in the MakeUp operation.
Sulfur Condenser Heat Curves
You can now generate heat curves for Sulfur Condensers within the SRU Sub-Flowsheet. You can also view the heat curves within a plot.
Aspen HYSYS Upstream Improvements
New PIPESIM Link
The legacy PIPESIM Link was replaced with a new PipesimLink Extension. Like the previous PIPESIM Link, this operation allows you to use the PIPESIM software package within an Aspen HYSYS framework. PIPESIM 2017 and later versions are supported, allowing you to take advantage of newer functionalities within PIPESIM.
OLGA Link Improvements
A new Runtime Mode check box on the Setup tab | Server page of the OLGA Link lets you use OLGA in Runtime mode when using the HYSYS-OLGA Link.
The new Compositional Tracking feature (available on the Setup tab | Components page) links with the compositional tracking version of OLGA. The compositional model tracks the changes in composition as a function of time and space.
AI Training Improvements
The following new features are available in AI Training objects:
When importing data from Excel, the Import Wizard now provides options for data not strictly in the template format, provided that the data has timestamps as row labels.
The estimated training time and a progress bar has been added under the AI Training Progress plot.
On the Build Model form, you can specify the Weight for each dependent variable. This allows some variables to have more or less impact on the trained model.
On the Build Model form, the Variable importance calculation check box allows you to specify whether or not additional calculations are performed at the end of training to determine the relative importance of each variable in the neural network model.
On the Build Model form, you can now choose to include or exclude trained variables in the model.
On the Build Model form, you can now choose which independent variables you want to use as inputs to the neural network. You can also choose which independent and dependent variables you want to use as inputs to the hybrid model. Note that independent variables used as inputs to the neural network are automatically used as inputs to the hybrid model.
On the Build Model form, the number of variables included in training, excluded variables, independent variables, dependent variables, and total variables is now reported.
On the Analyze Results form, you can modify the limits used in color-coding R2 values.
On the Analyze Data form, you can now view Trendlines on scatter plots.
On the Analyze Data form, you can now view Distribution Plots (box plots) for further data analysis.
The scale for charts features broader ranges, and plots have grids to improve usability.
Performance has improved for cases with a large number of data points (for example, more than 5000) even when loading cases or moving between tabs. Adding variables is also faster than in V12.1.
When entering formula tags, in the Tag Specifications View dialog box you can click Validate to check the syntax of the formula.
You can now save plots, after opening them in a separate window. A new Plots object manager has been added to store the saved plots, and can be accessed via the navigation tree under the AI folder.
Plant Data Improvements
Aspen HYSYS V14 features the following improvements for Plant Data:
You can now use Aspen Connect instead of Aspen CIM-IO & Process Data:
Aspen Cloud Connect V14 is required. It may be installed on any server which your computer can connect to and which can reach the historian.
If you use Aspen Connect instead of Aspen CIM-IO & Process Data, you do not need to install Process Data and ADSA.
To connect with Aspen IP.21, Aspen Connect uses IP.21's gRPC Server. If you are using Aspen IP.21 V14, no special steps are needed. If you are using an older version of Aspen IP.21, see requirements in the Aspen Engineering V14 Installation Guide.
For information about the supported data sources and how to configure them, see Adding End Points in the Aspen Connect help.
See Compatibility Notes for restrictions when using Aspen Connect.
A new Linear Interpolation option is available for the If not good drop-down list on the Data Validation tab of the Tag Manager form. This option linearly interpolates the conditioned value from the last previous good point and the first subsequent good point.
When entering formula tags, in the Tag Specifications View dialog box you can click Validate to check the syntax of the formula.
FlexCel is now supported. By default Excel files will now be imported via FlexCel. Accordingly, a new Options button has been added to the Plant Data | Advanced ribbon, that allows you to switch between using Microsoft Excel and FlexCel.
Safety Analysis Improvements
Entrance Fittings Available for Line Sizing
In V14, you can now select entrance fittings for inlet pipes in line sizing (in Rating mode) to account for movement from the vessel into the inlet line. The following fittings are provided:
Fitting Type
K
Data Source
Entrance: Sharp-Edged 0.5 Crane TP 410, page A-29
Entrance: Rounded, r/d 0.02 0.28 Crane TP 410, page A-29
Entrance: Rounded, r/d 0.04 0.24 Crane TP 410, page A-29
Entrance: Rounded, r/d 0.06 0.15 Crane TP 410, page A-29
Entrance: Rounded, r/d 0.10 0.09 Crane TP 410, page A-29
Entrance: Well-Rounded 0.04 Crane TP 410, page A-29
Entrance: Inward-Projecting 0.78 Crane TP 410, page A-29
Support for Additional Properties in Safety Datasheets
The following additional fluid properties are now available within custom datasheets for two-phase calculations:
Molecular weight for both phases
Dynamic viscosity for both phases
Customized Discharge Coefficients for Custom Orifices
You can now customize the discharge coefficients for custom orifices using the Orifice Manager. You can modify the Vapor Kd, Liquid Kd, and/or Mixed-Phase Kd values.
New User Specified Fitting Type
For the Rating line sizing method, a new User Specified fitting type is available. Selecting this option allows you to edit the K, L/D, and Source fields.
Calculated K Value Reported for Swages and Tees
For line sizing, the calculated K value for swages and tees is now reported.
Pressure Safety Valve (PSV) Data Included in HFL Files and Copy/Paste Supported
PSV data is now included in .hfl files, which can be used to import data into other flowsheets.
Copy/paste of streams and unit operations containing PSV data is now allowed. PSV sizing attached to any streams in the copied data will be included and merged into the destination case on paste or import.
New Wetted (NFPA-30) Fire Method
For Fire scenarios, a new Wetted (NFPA-30) Fire calculation method is now available. Wetted (NFPA 30) Fire calculations use the NFPA 30: Flammable and Combustible Liquids Code. NFPA 30 calculations are similar to API 2000 calculations. The primary difference is how wetted area is calculated. For wetted area calculations, for horizontal and spherical vessels, as with API 2000, there is a minimum area of 55% of spherical and 75% of horizontal vessels (imposed regardless of liquid level or flame height). Aspen HYSYS takes the greater of the following two values:
Wetted area to flame height
55% for spherical vessels / 75% for horizontal vessels
Vertical vessels function the same as for API 2000, just with the different default maximum flame height for Wetted (NFPA 30) Fire, which is 9.14 m / 30 ft.
Direct Integration (HEM) Orifice Sizing is now Allowed for Semi-Dynamic Fire Scenarios
For Fire scenarios using the Semi-Dynamic Flash calculation method, the Direct Integration (HEM) method for orifice sizing is now allowed and can be selected from the Relieving Phase - Method drop-down list.
Recalculation Enhancement
Previously, upon entering the Safety Analysis environment all systems were recalculated completely regardless of whether the inputs were changed since the previous entry. This had a significant performance impact on entry when there were a lot of calculations to re-run. Now line sizing results are preserved, and calculations will only re-run when changes have been made to corresponding reference streams.
Note: A file from an older version will always be fully recalculated upon the first entry to the Safety Analysis environment.
Aspen HYSYS Petroleum Refining Improvements
New MB Model Container Operation
A new MB Model Container operation is available in Aspen HYSYS V14. It provides a simplified, streamlined user interface compared to the Molecule-Based Reactor model and does not require you to specify operating conditions or kinetic parameters. You can use the MB Model Container to manipulate feed properties using a molecule-based framework. It serves as a connector between the molecule based and rigorous frameworks.
In this new MB Model Container operation, you can create a "short-cut" Aromatic Extraction Bed model, MB HDO (green diesel) Feed model, MB Property model (contains important properties, e.g. RON, cetane number, viscosity, freezing point, PIONA, and distillation properties) and a Naphtha Feed Transformer model. The MB Model Container also allows you to model a rigorous Aspen plus extractor into the HYSYS flowsheet and use it to model the extraction of aromatics.
The extraction unit is used to separate reformer product or straight run naphtha. The rich aromatic phase is sent to aromatic conversion units.
Hydrocracker / Resid Hydroprocessor Improvements
In V14, additional properties are available for Hydrocracker / Resid Hydroprocessor model calibration. The Product Meas. tab | Heavy Liquids page of the Hydrocracker / Resid Hydroprocessor Calibration view now contains additional product measurements that can be used to calibrate the model: Paraffins (both wt % and vol %), Naphthenes (both wt % and vol %), Aromatics (both wt % and vol %), MON, RON, Freeze Point, Smoke Point, Pour Point, Cloud Point, Cetane Number, Viscosity@38C,Viscosity@50C, Viscosity@60C, and Viscosity@100C.
On the Results tab | Reactor page of the Hydrocracker / Resid Hydroprocessor Property view and Analysis tab | Reactor page of the Hydrocracker / Resid Hydroprocessor Calibration view, the result name Aromatics [%] has been updated to Ca [%] (Carbon Aromatics).
Catalytic Cracker Improvements
ZSM-5 catalyst factors are now exposed and can be pasted into AI Training.
Alkylation Unit Improvements
Since the Alkylation Unit exclusively produces paraffins, the product stream for an Alkylation Unit now has paraffins by volume and by weight set to 100%, with olefins, naphthenes, and aromatics set to 0.
Additional chemistry was added to the Alkylation Unit to model disproportionation reaction and cracking reactions.
Delayed Coker Improvements
The SCD yields now reflect the yields of actual cuts rather than square cuts. Accordingly, a new table of SCD properties is reported in the Simulation tab of the property view to reflect the predicted properties from SCD cuts. In the Calibration tab of the property view, the calibration targets of SCD yields have also been changed to reflect the real SCD cuts.
The Delayed Coker unit now has better calibration results.
The recycle properties in the simulation and calibration have been improved to give better predictions.
Molecule-Based Reactor New Features and Improvements
For Hydroprocessing Bed and Hydrotreater model types, a new model template has been added to model a base oil unit operation, which is essentially a hydroprocessing unit specializing in the hydroisomerization of gasoil. The names of the model templates are Single Bed Base Oil Reactor and HTR Base Oil Reactor respectively.
When either of these new model templates are loaded, you can also specify Viscosity K1 and K2 parameters, and view the product viscosity.
When either of these new model templates are loaded, you can also specify the following Rate Law Parameters:
Dealkylation/Sidechain QSRC Sidechain NO Parameter
Paraffin Cracking QSRC SC NO Parameter
Dealkylation/Sidechain QSRC Invert Carbon No Parameter
Paraffin Cracking QSRC Invert Carbon No Parameter
You can now input mass and volume flowrates in the Feed and Hydrogen streams.
In the Solver Settings for the MB Reactor, a Pop up Editor to Modify Compositions check box has been added, allowing you to enable or disable the pop up window for detailed composition editing. This is also available in the new MB Model Container operation.
On the Calibration Results page, objective function contributions are now displayed. These will appear in a new Calibration Analysis table. This is also available in the new MB Model Container operation.
Aromatic Production Bed models are now available. Accordingly, three aromatic bed model templates are now available for Xylene isomerization, Toluene disproportion, and C9 heavy aromatics transalkylation respectively. The model template names are:
Aromatic C8 Isomerization Bed
Aromatic Toluene Disproportionation Bed
Heavy Aromatic Transalkylation Bed
HDO Bed (hydrodeoxygenation) reactor is now available. This will enable you to model bio-feed conversion to hydrocarbons.
The Calibration | Feed Specifications page has been realigned to be consistent with the Simulation | Feed Adjustor | Feed Specifications page.
For MB Aromatic Reactors, the following feed components have been added; Prehnitene, IsoDurene, Durene, and A10 Naphthalene.
On the Calibration | Reactor Section page, you can now pull data directly from the simulation and use it for calibration.
Co Feed Hydroprocessing Bed - A Co Feed model template has been added to the Hydroprocessing Bed Model Type. This is a combination of a HDO Bed and a Hydroprocessing Bed feed, which will enable the modeling of hydrotreating for a mixture of bio-feed and hydrocarbon feed.
Visbreaker Improvements
PONA (Paraffins, Olefins, Naphthenes, Aromatics) properties have been added to the Visbreaker operation.
New Example Cases
The following example cases have been added to the Aspen HYSYS V14.0 | Samples | Refining Cases folder:
Heavy_Aromatics_Transalkylation_Example.hsc - This example case models transalkylation of heavy aromatics to xylene isomers using an Aromatic Production Bed.
Hydroconversion_of_Soybean_to_Hydrocarbons_Example.hsc - This example case models hydroconversion of soybean to hydrocarbons.
MBRXRBed_COFeed_ARM_Example_Case.hsc - This example case models a hydroprocessing bed with a HDO/HCR co-feed.
Production_of_Green_Diesel_with_Waste_Cooking_Oil_Example.hsc - This example case models the conversion from waste cooking oil to green diesel using a HDO Bed.
RHP_2parallel.hsc - This example case models a Resid Hydroprocessor.
Simulation_of_Aromatics_Complex_Example.hsc - In this example case, a naphtha stream is catalytic reformed by a CCR. The products are separated into two parts. The first part mainly contains toluene, which undergoes the toluene disproportionation process to obtain xylene isomers. The second part mainly contains C9 aromatics; the C9 aromatics then undergo transalkylation reactions to generate xylene isomers. The xylene isomers then isomerize to obtain more valuable p-xylene.
Simulation_of_Aromatics_Complex_Example_AspenPlus_Extractor.hsc - Similar to the aforementioned case but contains a MB Model Container with an Aspen Plus model connected to it.
Toluene_Disproportionation_Example.hsc - This example case models disproportionation of toluene to xylene isomers using an Aromatic Production Bed.
Most example cases come with an accompanying PDF document, describing the example case in greater detail, which can be found in the Aspen HYSYS V14.0 | Samples | Refining Cases folder.
Aspen Assay Management Improvements
Assay Similarity Search
In V14, when you want to replace a certain assay in your crude basket, you can use the assay similarity search function to find similar assay(s) in a group of assays, which can be used as a replacement. Assay Management measures the assay similarity by Frechet Distance. The smaller the Frechet Distance is between two curves, the more similar the two assays are to each other. For easy understanding, the Frechet Distance value is converted to the similarity value when displaying the similarity results. A larger similarity value means the assay is more similar to the assay that will be replaced.
API 2011 FlashPoint Correlations Added
The following FlashPoint correlations have been added from the API Technical Data Book - 10th Edition.
API 2C1-1-1 (2011)
API 2C1-1-2 (2011)
API 2C1-1-3 (2011)
API 2C1-1-4 (2011)
API 2C1-1-5 (2011)
These are available for selection in the Correlation Manager and the Property Manager (AAM).
Generate Simultaneous Distillation Plots
