不知道大家为什么被Ribbon界面给糊弄住了。
真的没什么大的变化。附上一段文字说明V8.0的更新。
不管是老界面还是新界面，核心的东西没有怎么变。
知其然知其所以然！
What's New in Aspen Plus V8.0
Integrated Analysis
Aspen Plus now has the ability to automatically perform costing with each run. This can be controlled with a new checkbox Auto-Evaluate on the Economics tab of the ribbon.
It is now easier to perform energy and economic analysis on Aspen Plus models. The Activated Analysis panel, accessible from the Home tab of the ribbon, lets you run each analysis with a single click and displays a summary of results. The analyses are automatically updated after each run. The energy analysis allows you to study possible energy-saving changes in your plant interactively in the Energy Analysis environment.
The Plant View feature allows you to view measured plant data beside simulation results, when a model is connected to a source of plant data. Click Plant View on the View tab of the ribbon to open this view.
Example Files
aspenONE Exchange now lets you access many additional model files and documentation via the Internet. Start it from the Get Started tab of the ribbon.
There are several additional example files delivered with Aspen Plus in the Examples folder and its subfolders:
Several new CO2 removal using amines and the unsymmetric electrolyte NRTL model in the Amines_ENRTL-RK subfolder
A new model for the caustic evaporation process
A new model for urea synthesis and granulation, which extends the existing urea synthesis model to include the solids processing operations, in the Urea subfolder
A new example for the crystallization and drying of sodium chloride
Solids Unit Operation Models
A new unit operation model, Granulator, has been added. This can be used to model granulation and agglomeration processes, those in which small particles are made larger by granulating or coating processes.
A new unit operation model, Classifier, allows you to model gravity-based solid classification units such as elutriators and sifters.
Screen has been updated with new capabilities from the SolidSim Screening model. This includes 5 new types of selection function, offset of fines, additional methods for specifying the entrainment of fluid phases entering the screen, the ability to specify multiple-deck screens in a single Screen block, and additional results.
Crusher has been updated with new capabilities from several SolidSim mill and crusher models. There are additional breakage and selection functions, as well as an alternative mechanism for specifying outlet particle size distribution based on distribution functions.
Dryer has been updated with detailed models of convective dryers. The original, shortcut dryer has some additional capabilities as well. The results are now much more detailed. The convective dryer model requires explicit solid and gas feed streams, so the old multi-stream input port has been split into two single-stream inlet ports. See Compatibility Notes.
Cyclone has been updated to add a number of additional built-in cyclone configurations, and the Muschelknautz efficiency correlation from SolidSim, along with its different design mode (in Design mode with Muschelknautz, specify number of cyclones and pressure drop to have Cyclone select the best-performing cyclone configuration).
VScrub has been updated. In addition to Yung's model for the venturi scrubber, now Calvert's model is also available. In addition to modeling venturi scrubbers, there is also now an option to model spray towers.
Crystallizer has a new option to calculate the outlet particle size distribution from a distribution function.
CFuge has been updated. In addition to the perforated basket centrifuge offered in previous versions, there are now models added for the decanting centrifuge, pusher centrifuge, and disc separator.
ESP has been updated. There are new models for the parallel plate electrostatic precipitator, as well as an option to model wire-in-tube precipitators.
ClChng now copies data between different substreams of the same type. In previous versions, it could only copy between substreams with the same ID. Now it allows you to copy, for instance, the CISOLID substream to the CIPSD substream, creating an empty PSD (with missing values) as it does so.
The Substreams and Moisture Comps forms under the Setup folder have been merged into a new Solids form, with a new object manager for specifying particle size distribution (PSD) meshes (the lists of size intervals).
If you define multiple PSD meshes, you can now specify which mesh to use for specifying data for each stream directly in the CI Solid or NC Solid sheet for that stream. If you use a mesh other than the default for the stream class, the data you enter will be mapped into the size intervals for the stream class, possibly generating a warning if the particle size range for the stream class does not cover all non-zero intervals in the specified data, or an error if the fractions do not add to 1 (within a tolerance) after mapping.
You can also choose to use a distribution function to specify the PSD for a stream, and Aspen Plus will calculate the PSD fractions to match the distribution.
The Stream Results form in each block, stream, and the Results Summary now contains a Solids sheet showing particle size distributions of streams, when available. There is now a built-in plot for particle size distributions, as well.
Data on the Flowsheet
You can now define up to 6 properties to be shown directly on the flowsheet in the same manner as temperature, pressure, and other global data are now shown.
You can also define Custom Tables of data by copying and pasting variables from other forms, and display these on the flowsheet as a live table or as an icon.
Descriptions for streams and unit operation models are now displayed as long names in tooltips on their icons in the flowsheet, on their names in the navigation pane, and other places.
Tracker on Plots
A new feature on plots, the Tracker, provides crosshairs that move along the curve as you move the mouse, showing the X-Y coordinates of the point at the crosshairs. To enable it, in the Plot Format tab of the ribbon, in the Display group, check the box for Tracker.
Distillation Models
On RadFrac's Setup form, the Thermosiphon Config. and Reboiler sheets have been merged. The Report | Pseudo Streams sheet has been merged into the Setup | Streams sheet with other stream specifications. A new Specification Summary form allows you to view and edit the operating specifications, design specifications, and varied variables all in one place.
The forms for RadFrac have been reorganized into a set of folders, grouping related forms together. The EO-related forms have been similarly grouped for other blocks.
The Glitsch tray sizing procedure used in RadFrac, MultiFrac, and PetroFrac has been improved. Previously the Glitsch shortcut method was used; now the rigorous method is used. This now provides several additional sizing results, sufficient to reproduce the results in a rating calculation.
The HanleyStruc (2010) mass transfer and interfacial area correlation for sheet metal structured packings in Aspen Rate-Based Distillation has been extended to include another version of this correlation that applies to metal gauze packings.
HeatX
HeatX now allows phase splitting into 2 or 3 outlet streams from each side of the exchanger, and the new Setup | Streams sheet allows you to assign which phases go into each stream. This replaces the old mechanism that just allowed a second stream for free water decant.
The interface between HeatX and Aspen Exchanger Design and Rating programs has been improved. You can now Size Shell&Tube or Size AirCooled from the Setup | Specifications sheet to perform sizing calculations. For this sizing calculation, you can use EDR defaults or a template you select to supply geometric options. You can then update the Aspen Plus model to use this EDR result or just save it as a separate EDR file. Also, the setting plan, tube layout, and profile plots from EDR are now available on the EDR Shell&Tube Results and EDR AirCooled Results forms.
Rigorous HeatX design now allows you to use an EDR template file (*.edt) to define the initial configuration. A *.edr file may also be used as the template; if you do so, the predefined parameters in this file are ignored.
Flash Specifications
In many unit operation models, the flash specifications have been redesigned so that each possible specification has a dedicated field, and you can select which specifications are active. This allows you to switch between different specifications while retaining the values for the ones not currently in use.
Utilities
The Utilities object manager has a new option to require utilities specifications for all utility exchangers. When this is checked, blocks which support utilities are marked incomplete if they have heating or cooling without a utility specified.
There is now a Utilities Library which contains preconfigured utility blocks. When you create a new utility block (either on the Utilities object manager or in a block's utilities specifications), you can use one from the library instead of a blank one. It is possible to add your own preconfigured utilities by editing the Utilities Library's XML file.
The Model Summary grid now allows you to customize the grid, save customized versions as templates, and export the grid to Excel. The Excel report can be activated as a live Aspen Simulation Workbook interface to your model.
Property Sets
EXERGYML and EXERGYMS are new property set properties for exergy, calculated on a mole basis and a mass basis, respectively. EXERGYFL is exergy flow rate. These properties use a reference temperature and pressure specified on the Setup | Calculation Options | Calculations sheet.
A number of new property set properties related to solid particles have been added:
D10, D20, D25, D50, D63 (63.2%), D75, D80, and D90 are the particle diameter greater than X% of the solids mass for solids with particle size distribution.
D25:D75 is the ratio D25/D75, a measure of the width of the particle size distribution.
D1_0, D2_0, D2_1, D3_0, D3_2, and D4_3 are ASTM derived diameters D[1,0], D[2,0], D[2,1], D[3,0], D[3,2], and D[4,3].
VSSA is specific surface area and SMD is Sauter mean diameter.
Equation-Oriented Modeling
Two new commands have been added to the EO Analysis group on the Equation Oriented tab of the ribbon. Block Stats displays statistics for all blocks. Model Stats displays information about the size of the problem and the number of degrees of freedom. This information appears in the Control Panel for both commands.
User Models
A new Fortran compiler option was added to compilers.cfg to support the latest release of Intel Fortran 12 which comes bundled with Microsoft Visual Studio 2010 as linker. (The previous release used Microsoft Visual Studio 2008.)
The CALUPP property monitor (accessible from Fortran user models) can now access user properties (from the Customize | User Properties form in the Properties environment) in addition to built-in Property Set properties.
PPEXEC_USER now contains a new flag you can set to disable the mass balance check. Use this if you create a user model like Mult or a distillation column with pseudostreams which intentionally does not maintain mass balances.
Physical Property Models
Mixture diffusivity models Wilke-Chang (DL1WCA) and Nernst-Hartley (DL1NST) now have a second option code which specifies which liquid mixture viscosity model is used to provide the mixture viscosity: Andrade (0, default), quadratic mixing rule (1), or Aspen (2).
The Mathias-Copeman and Schwartzentruber-Renon-Watanasiri alpha functions, which have previously been available for certain equation-of-state models, are now available for all Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) based models via an option code. See Soave Alpha Functions or Peng-Robinson Alpha Functions for information about these functions.
Aspen Properties Enterprise Database
On Windows Vista and Windows 7, the new SQL LocalDB feature is now supported and used by default. This greatly simplifies the installation procedure for the typical case where you are not sharing custom databanks with anybody else.
The LocalDB runs as a standard program, not a service, so there is no service to configure. Aside from simplifying configuration, this is compatible with site policies that prohibit SQL Server.
The LocalDB is not accessible over the network. No other computer can access any custom databanks you install or create on your computer in LocalDB.
Databases in LocalDB cannot be cloned, nor can you clone databases from elsewhere into LocalDB. Other mechanisms for copying data work.
Other than the above exceptions, LocalDB provides the same features as SQL Express. All features of Aspen Properties Enterprise Database (APED) other than network access are supported with LocalDB.
The first time you start Aspen Plus in a LocalDB-enabled version, the Aspen system databases will be loaded into the LocalDB. A message box will be displayed while this happens.
Microsoft does not support LocalDB on Windows XP. Also, LocalDB is not supported on server versions of Windows since LocalDB is designed to support a single user. On these versions of Windows, SQL Express will continue to be used by default, as in previous versions.
You can configure APED to use an installed SQL Server or the legacy databanks on any version of Windows. These options work the same as in previous versions, except that to configure APED to use SQL Server you must clear the Use LocalDB checkbox on the configuration dialog box.
User Databanks
In previous versions, it was possible to create databanks using legacy databank files which contained component aliases longer than 12 characters or component names longer than 32 characters, but when you attempted to use those compounds in a simulation, Aspen Plus would crash. Now APED enforces the 12 character limit on aliases and informs you if it finds overly long names when building a databank. The 32-character limit on component names has been removed, and you should be able to use the longer names in simulations, with two exceptions:
In report and history files, only the first 32 characters of the name will be printed.
In the input file, extremely long component names will be truncated to maintain the 74-character line length limit. If you use the option (in File | Options | Properties Basis) to identify compounds by alias (the default), then this will not affect you. However, if you use the option to identify compounds by component name, you will not be able to use components with such long names.
Ribbon Commands
Some commands have been moved, renamed, or added to the ribbon for ease of use. These include:
Home tab:
A new Activated Analysis command has been added to show the Activated Analysis panel. This replaces the Energy Analysis command that was present previously.
Economics tab:
The Operation Cost group has been renamed Prepare, and the Cost Options command has been moved into it.
Material Cost has been renamed to Stream Price.
A new group Economics Solver has been added. The Activate Economics command is now a checkbox named Economics Active in this group, and Delete Scenario has also been moved into the group. The new command Auto-Evaluate appears in this group.
The Model Summary command (which also appears on the Home tab) has been removed from the Economics tab.
The Status indicator has been expanded to show the Mapping, Sizing, and Evaluation statuses separately.
Equation-Oriented tab:
Block Stats and Model Stats commands have been added in the EO Analysis group.
The shortcuts to the Global Scripts, Local Scripts, and Assign Scripts forms have been combined under a Scripts button to save space.
The shortcut to the EO Configuration | Ports form and the History File command have been removed. (You can still access the history file from the Home tab.)
View tab:
The Model Palette button has been moved from the Flowsheet Modify tab to the View tab.
Developer tab:
This tab has been renamed to Customize.
New command added for Custom Tables.
Flowsheet Modify tab:
Model Palette command has been moved to the View tab.
Find Object command added.
