Aspen Acol+ 15

New Features and Enhancements

Release 2006.5 includes the following new features and enhancements: Design and rating calculations utility for Acol+ model.

New Transfer UA to End Point button. Option for use of Moore Fans.

Data Transfer capability from Acol+ to Plate+ and Tasc+. Design constraint in Acol+ design mode.

Output in detailed interval analysis. Input for explicit setting plan dimension. User-specified recap profiles.

Pre-defined slots and user-saved plots. SaveAsEdr utility.

Process-side heat transfer enhancements. Interface option for HYSYS process simulator. Interface option for Aspen Plus process simulator. Support for Aspen OSE Workbook

HYSYS simulator interface to provide Design and

Rating calculations from an Acol+ model

A new HYSYS utility to design or rate any existing air cooler in the flow sheet is now available and includes the following features:

The utility can use either the specified process conditions or copied process condition from the selected air cooler and do a design or rating calculation.

Design allows you to use the Acol+ design optimization logic to find best exchanger geometry for the current process conditions

Rating allows you to evaluate how much over or surface the current exchanger geometry is for the current process conditions.

The new utility includes the following buttons:

o A Run button is used to design or rate the selected air cooler independently from the

HYSYS solver.

o A Transfer geometry from air cooler button is used to transfer geometry from the selected air cooler to do rating calculation

o A Transfer geometry to air cooler button is used to transfer the calculated geometry from design to the selected air cooler.

o The new Transfer UA to End Point button transfers the calculated UA from Acol+ engine to constant UA input and sets the Air Cooler Model to Air Cooler simple design model.

(19)

Aspen Acol+ 16

Option for Use of Moore Fans

Acol+ can use Moore fan correlations to select fan diameter and number of fans. Compared with the standard fan selection method, the Moore Fans size selection is a more detailed fan selection based on typical fan size used by the Moore Fan manufacture. After fan diameter and number of fans are determined by Moore fan correlations, the program then uses the selected fan diameter and number of fans to determine all other fan

characteristics.

Data Transfer Capabilities from Acol+ to Plate+ and

Tasc+

Acol+ can transfer input and results to Plate+ and Tasc+. Tube-side process conditions and physical properties are transferred to hot- or cold-side depending upon whether tube side is being heated or cooled.

Design Constraint in Acol+ Design Mode

Acol+ can use maximum face velocity as a design constraint to design air-coolers. In Acol+ design mode with varying outside flow, the program evaluates all outlet temperature points and corresponding flows, then, the program selects the candidate that has the best

maximum face velocity and shows it as the final design.

Process-Side Heat Transfer Enhancements

Experimental and analytical research has shown that the mixture condensation heat transfer methods can be over conservative when there is no non-condensing gas. An enhancement was made to the implementation of film mass-transfer correction that gives higher heat transfer coefficients. Also, an adjustment was made to the method for calculating the heat transfer coefficient when the liquid heating duty is a large fraction of the total duty in a boiling stream. This enhancement generates higher heat transfer coefficients.

Output in Detailed Interval Analysis

Acol+ now displays the following coefficient information:

Condensing coefficient in interval analysis for tube side condensing application. Boiling coefficient in interval analysis for tube side vaporizing application.

Input for Explicitly Setting Plan Dimensions

Acol+ now allows input to explicitly specify setting plan dimension. The previous version uses a set inputted dimension ratios to arrive at some approximate fan, fan motor, and plenum dimensions of an air cooler unit. The new input is placed on the same screen with corresponding ratio. If actual dimension is specified, it overrides any specified ratio. The explicitly specified setting plan dimensions are only used in setting plan drawing.

(20)

Aspen Acol+ 17

User-Specified Recap Profiles

Acol+ now allows you to establish a number of different Recap Lists of variables using user-specified Profile names. The Recap feature allows you to easily compare results from different runs side-by-side. You always had the capability to customize this list for a given run. However, you can now save a customized list of variables under a Recap Profile Name and use it with any subsequent application runs. As a result, you can save time by not having to customize a list for every run.

Pre-defined Plots and User-Saved Plots

Acol+ has always allowed you to plot specific data from the detailed calculation tables using the plot wizard supplied with the program. However each application run required that you redefine the plots you wanted to see. A large number of pre-defined plots were added, and you can now select from these plots to see plotted data. In addition, you can also define a custom plot and save it as a default plot for the program. The saved plot is then available for all subsequent application runs.

File Conversion Utility

You can now convert ACX input files to Acol+ input files using the File Conversion utility on the Windows Start | Programs | Aspen Tech | Aspen Engineering Suite | Aspen

HTFS+ 2006.5 | Conversion Utility menu. The conversion utility converts one or more

selected files to the Acol+ input format. The files maintain the same filename but have the EDR file extension.

HYSYS simulator option to transfer Acol+

calculated UA to End Point model in HYSYS

The HYSYS Simulator interface now includes a button that you can use to transfer the calculated UA from the Acol+ engine to a constant UA input and set the Heat Exchanger Model to End Point.

Aspen Plus simulator option to transfer Acol+

calculated UA to End Point model in Aspen Plus

The Aspen Plus simulator interface now includes a button that you can use to transfer the calculated UA from the Acol+ engine to constant UA input and set the Heat Exchanger Model to End Point.

Acol+ application now supports Aspen OSE

Workbook

Aspen OSE Workbook is an Excel Add-in tool which links process simulation models to Excel. Absolutely no programming knowledge is required to use this tool. Aspen OSE Workbook contains tools to link simulation variables from HTFS+ applications to Excel worksheets and via Excel worksheets to other simulators.

(21)

Aspen Acol+ 18

Additional tools are available in OSE Workbook to select and run HTFS+ models. Aspen OSE Workbook makes it easier to deploy models in Excel and offers performance benefits over previous methods such as OLE links and VBA. Aspen OSE Workbook is part of the Open Simulation Environment Base offering.

(28)

Aspen Adsim 25

Support for Visual Studio .NET 2005

Aspen Adsim 2006.5 now supports the use of Microsoft Visual C++ .NET 2005 for creating C/C++ procedures and for exporting models for use in Aspen Plus. Previous versions of Visual C++ are not supported.

Aspen Adsim 2006.5 also supports the use of Microsoft Visual Basic .NET 2005 for creating custom forms. It also supports Microsoft Visual Basic .NET 2003 and Microsoft Visual Basic 6.

Aspen Adsim 2006.5 supports the use Intel Fortran 9.0 or 9.1 for creating Fortran procedures. This is unchanged from Aspen Adsim 2006.

Touched Variables Always Shown in Black

If you change the value of a variable from its default, the variable value color changes from blue to black. In previous versions, if you changed the variable value back to its default, it would change back to blue. It now remains in black to show that you have changed the value, even though the value is equal to the default. The value only reverts to blue if you right-click on the value and select Reset to Default. This makes it easier to see all values that you have deliberately entered.

Compatibility Notes

The following lists and describes compatibility notes and issues for release 2006.5: You can now install and use Aspen Adsim 2006.5 at the same time as Aspen Adsim 2006 and other previous versions of Aspen Adsim. However, consider the following compatibility issues when upgrading your existing simulations to Aspen Adsim 2006.5:

The ImpEuler (11.1), VSIE (11.1) and Gear (11.1) integrators are old implementations that have been superseded by the Implicit Euler and Gear integrators that were

introduced in the 12.1 release. Theses were included in the 12.1, 2004 and 2004.1 versions to give time for transition of existing simulations to the new integrators. These integrators were withdrawn at version 2006. If you load a simulation that uses one of these integrators, it automatically switches to the equivalent newer integrator, and selects option- and tolerance- values that match the old integrator as closely as possible.

Aspen Adsim Language (.ada) files generated using previous versions are compatible with Version 2006.5. You may see some warning messages when loading an Aspen Adsim file from a previous version into Aspen Adsim 2006.5. This is a result of some solver options that have become obsolete or have been renamed. Saving the file in Aspen Adsim 2006.5 eliminates these warnings.

Aspen Adsim Document (.adb) files exported from previous versions Aspen Adsim cannot be loaded in Aspen Adsim 2006. Load these files into the previous version and export them as .ada files, which can then be loaded into Aspen Adsim 2006.

(29)

Aspen Adsim 26

When using Aspen Properties/Aspen Plus property package: If your Aspen Adsim 2006.5 input file includes the Aspen Properties property package, you can load it directly into Aspen Adsim 2006.5. If you are using an external property package in the form of an Aspen Plus .appdf file or an Aspen Properties .aprpdf file, then these files created with earlier versions of that software are not compatible with Aspen Adsim 2006.5. If you try to load a physical properties file (.appdf or .aprpdf) that was generated using an earlier version of Aspen Plus or Aspen Properties, the following error message appears:

SAIPIN-F-Error loading Aspen your .appdf File. Please refer to the Aspen Properties error messages first, or it may be due to an incompatible PDF file version. You should leave the application and reload your input file once you have rectified the problem.

After you receive this error, exit Aspen Adsim before loading any further simulations. To continue, you must regenerate the .appdf file using Aspen Plus 2006.5 or Aspen

Aspen Batch Plus 30

Aspen Batch Plus

Product Description

Batch Plus®_{is a recipe-oriented batch process modeling environment that spans the batch}

process development value chain from discovery through manufacturing, enabling companies to bring new products to market at greater speed and reduced cost.

New Features and Enhancements

Release 2006.5 includes new features and enhancements in the following areas: Simulation Engine and Operations

Data Management

Simulation Engine and Operations

Release 2006.5 includes the following new features and enhancement to Simulation Engine and Operations:

Scheduling of process campaign for a production plan. Campaign overlap and batch overlap for a production plan. Automation of simulating step batches and production plan.

Consistent way of displaying emission control devices in the schedule view. Emission control devices in multiple-use.

Aspen properties flash option for condensers. Blanket pressure added to set-state operation.

Pack-column operation allows column to be partially packed.

Vent status for each vessel in operations is reported in quick results.

(34)

Scheduling of Process Campaign for a Production Plan

When a Process is used for a campaign in a production plan, Batch Plus calculates the

required number of Step batches belonging to the Process on the basis of quantity specified. Then the sequence of Step batches is generated through Step Key Input and Output

intermediates to produce its Final Product.

For example, suppose that a campaign contains a Process comprising Step A and Step B where Step A produces 25 kg of Step B Key Input Intermediate and Step B produces 100 kg of the Final Product of the Process. If 500 kg is specified for the Final Product for the

campaign, Batch Plus calculates that total Step batches required is 25 Step batches. Then Batch Plus generates the Step batch sequence of 4 batches of Step A, 1 batch of Step B, 4 batches of Step A, 1 batch of Step B. In previous versions the sequence generated was 20 batches of Step A and 5 batches of Step B. This enables Process campaign to be used more realistically to scheduling and planning.

Campaign Overlap and Batch Overlap for a Production Plan

Batch Overlap was previously defined as whether or not the current campaign overlaps with the previous campaign. In release 2006.5, the name of Batch Overlap is changed to

Campaign Overlap and a new overlap was added: whether or not Step batches belonging to the current campaign overlap each other. This new Batch Overlap gives you more flexible production planning. This is another kind of Start-After scheduling constraint at the Step level – in addition to Operation/Unit Procedure Start-After constraints already delivered in the previous version.

Automation of simulating Step batches and Production

Plan

Simulate Batch is no longer required for simulating plan. In previous versions simulating all the Step batches one-by-one was required before simulating a Production Plan or Process. Release 2006.5 adds automate simulating of all the Step batches and then the Production Plan or Process using one button.

You can use this option by right-mouse-clicking on the production plan from the Plan explorer and selecting Simulate Batches and Plan item, or click on Run main menu as shown in the screenshot below. “Simulate bathes and Process” can be done in the same way.

(35)

Consistent way of displaying emission control devices in

the schedule view

In this version, turning on the air emission calculation option under

Tools|Options|Simulation Batch or …|Simulation Plan becomes a prerequisite for

displaying emission control devices in the schedule view. In previous versions, the display of devices in the schedule view depended on the types of devices in an inconsistent way, that is, batch type devices were always displayed regardless if air emission calculation option was turned on. Moreover, continuous type devices were also displayed if the option was turned on. In this version, if the option is turned off, batch type of devices does not display in schedule view.

Emission control devices in multiple-use

Emission control devices in multiple-use are no longer scheduling constraints in this version. Emission control devices can now be shared resources the same as Buffer Tank. When multiple-use for control devices is specified, it is possible to have two operations in parallel where the two operations use the same emission control device. For example, charge ST-A and ST-B are in parallel and both vessels vent to an emission control path containing condenser C-25. If C-25 is multiple-use, then the two operations can occur at the same time. If C-25 is not multi-use the Charging of ST-A and ST-B are not scheduled to occur at the same time even though they are parallel operations. Note that turning on the air

emissions calculation under Tools|Options|Simulation Batch is required to take this into account.

Aspen Properties flash option for condensers

Condenser emissions are calculated using the procedure outlined in the EPA’s

Pharmaceutical MACT regulation. A regulation for batch processing of Miscellaneous Organic chemicals requires the calculation of emissions from condensers using an iterative flash procedure instead. Emissions from condensers can optionally be calculated using an iterative flash in Aspen Properties. The setting is available in Preferences… | Vapor

Emission | Model Parameters | Flash Condenser Calculation.

Reflux-through-Dean-and-Stark operation allows reflux of

bottom layer of Decanter

The Dean & Stark decanter separates the immiscible liquid mixture by density difference. In previous versions the content of the top layer is assumed to be recycled to the distillation column and the content in the bottom layer is sent to a receiver. This version allows the contents of the bottom layer to be recycled to the distillation column and the content of the top layer to be sent to a receiver.

Quick Results|Streams tab shows all the streams around the decanter. Note that two immiscible phases, Liquid1 and Liquid2 represent the bottom and top layer, respectively.

Blanket pressure added to Set-State operation

In version 2006 we introduced the concept of State that is assigned to equipment through the Set State operation. The only state supported was agitation. In this version, blanket

(36)

pressure is added to maintain pressure in subsequent operations without Purge or Sweep operation first. Through the details dialog box you can set:

Blanket Gas Blanket Pressure

Pack-Column operation allows column to be partially

packed

Starting with version 2006.5, a column can be partially packed, that is, not from end to end. In case of a partially packed column, the bed-volume is the volume of packed volume

instead of physical volume of the chromatography column.

Vent status for each vessel in operations is reported in

Quick Results

The vent status is reported in Contents tab of Quick Results. It is reported for initial and final contents for the vessel. Vent status is also stored in MS Access results database, in the Equipment Contents table.

Heat transfer operations uses vessel specific minimum

approach temperature

In addition to specifying a single minimum approach temperature ( T) between the utility and contents for each project, a minimum approach temperature can be specified for each vessel being heated/cooled.

Data Management

Release 2006.5 includes new features that allow Batch Plus to interface with external Materials and Equipment databases

Open Materials and Equipment Databases

These features open Batch Plus so that it can read materials and equipment information from any materials and equipment database repositories. Batch Plus 2006.5 contains a set of public interfaces to which custom .dlls or assemblies can be written to interface any materials and equipment databases to Batch Plus. Once the custom .dll or assembly

interface functions are written, Batch Plus automatically accesses it for data. The materials and equipment selected from the central (remote) database are imported into your Batch Plus project.

Batch Plus 2006.5 also uses these interfaces to notify you when the remote database is updated and provides a choice to update the local project.

Compatibility Notes

(37)

Emissions may be lower in some simulations due to a change in the calculation of vapor pressures. If the temperature is below the freezing point for a component, its vapor pressure is 0. Previously, the Antoine equation was applied out of range at this temperature resulting in a very low or in some cases a negative number.

The Pack-Column is not upward compatible. You must manually update any project created prior to version 2006.5 which contains Column. This is due to the Pack-Column enhancement which requires the source of the packing.

Since the Pack-Column allows the column to be partially packed in version 2006.5, the subsequent column operations results might be different.

For the Line-Blow operation, the exhaust stream pressure from the destination vessel is different from the previous version; any emission for the operation is different as well. The Generic-Batch equipment class is no longer be shown as inventory location in any

operation.

Change in project and step database: the group ID for the Cake group changed from 200,000 to 200,158; the group index for First Wash has changed from 300,000 to 300,087. If you are referring to these fields in an Operating Instruction template, you must reenter values for those fields.

Aspen BatchSep 35

Aspen BatchSep

Product Description

Aspen BatchSep™ is an advanced tool for design and optimization of batch distillation columns. Its rigorous simulation capabilities enable you to quickly and cost-effectively determine the optimum design and operating policy for batch distillations. You can use it to help reduce batch times and/or improve product recovery while maintaining required product purities.

New Features and Enhancements

Aspen BatchSep 2006.5 includes the following new features and enhancements: Total reflux dump.

Operating Steps Upgrades. BatchSep in Aspen Plus. User interface Upgrades.

Total Reflux Dump

Aspen BatchSep includes the ability to dump the contents of the reflux drum straight into a receiver while operating at total reflux. The reflux drum is bypassed by connecting the condenser to the reflux line and closing the product distillate to operate at total reflux. This operation requires setting up a reflux dump receiver (or two if two liquid phases are present). In addition, an operating step must be set up that contains the following steps: Switch on dumping of the drum.

Define the receiver number to where the drum contents is dumped. A receiver is required per liquid phase present.

Operating-Steps Upgrades

The following lists and briefly describes operating-steps upgrades:

Column Pressure Drop, Stage Pressure Drop, and Stage Duty can now be modified in an operating step.

You can now specify a Maximum Duration for each operating step. If the trigger condition is not met within this time, BatchSep ends the operating step.

The Profile Results form was enhanced to display profiles at the end of each operating step.

BatchSep in Aspen Plus

Aspen BatchSep is now available as a distinct unit operation within the Aspen Plus unit operations model library. The Aspen BatchSep unit operation can be used when you want to model a semi-batch process containing one or more batch distillation columns and other continuous unit operations. You can use an Aspen Plus stream to transfer material between Aspen BatchSep and other unit operation blocks on the flowsheet.

User Interface Upgrades

The following modifications were made to the user interface to make it more consistent with the Aspen Plus user interface:

For input forms, changing the units no longer leads to a change in the value of the corresponding field. For results forms, the behavior is the same as in Aspen BatchSep 2006.

When the value in a field is the default value, it is displayed as grey instead of blue.

Compatibility Notes

The following describes compatibility notes and issues for release 2006.5:

If you load a simulation created in Aspen BatchSep 2004 or 2004.1 into Aspen BatchSep 2006.5, it is automatically updated to be compatible with the new capabilities in Aspen BatchSep 2006.5.

The first time you run the simulation, the Operating Steps regenerates and the simulation is re-initialized at time zero. After running for the first time, you should restart the simulation and save the file. As a result, the simulation does not need to be re-initialized again unless you make any changes to the configuration.

If your Aspen BatchSep 2004 or 2004.1 input file includes your Aspen Properties property package, you can load this directly into Aspen BatchSep 2006.5.

If you are using an external property package in an .appdf or .aprpdf file, the BatchSep 2004 or 2004.1 input file must be re-generated using Aspen Plus or Aspen Properties 2006. You can then load your Aspen BatchSep 2004 or 2004.1 file into Aspen BatchSep 2006.5.

Aspen Case Analysis 37

Aspen Case Analysis

Product Description

Aspen Case Analysis®_{is a simulation analysis tool compatible with HYSYS, Aspen Plus,}

Aspen Custom Modeler, and the layered products based on these technologies such as Aspen Polymers Plus. Use it to browse simulation cases, compare two or more case files, carry out trending studies, and run multiple simulation studies in a batch execution mode. Cases can be browsed, displaying a hierarchy of variables and their properties. The case browser displays simulation case files in a hierarchical data tree that allows you to step through the model data structure to view data and parameters defining the case. Multiple cases can be compared against a base-line case. The case comparison tool identifies variables which are added, deleted or changed compared to the selected base case models. The case comparison feature includes a number of filtering options to allow you to quickly isolate and identify differences between case files.

Aspen Case Analysis also includes a feature that allows you to define scenarios. Each

scenario consists of a list of selected input variables to change, and a list of output variables to monitor. These scenarios can be applied to a case, permitting variable trending and case-studies to be made. Scenario batch mode permits multiple scenarios to be applied to

multiple cases. Variable trend data can be viewed in plots (2- and 3-dimensional) via the Plotter facility.

Aspen Case Analysis is delivered as an installable component of Aspen Simulation Workbook product.

Stream data displayed on the flowsheet

The new Global Data option lets you view values of stream variables on your flowsheet, making it easier to visualize what is happening in your process model. You can switch display of Global data on or off from the View menu. You select the variables to be displayed from the Flowsheet menu or from the Context menu for a stream.

Support for Visual Studio .NET 2005

Aspen Chromatography 2006.5 supports the use of:

Microsoft Visual C++ .NET 2005 for creating C/C++ procedures and for exporting models for use in Aspen Plus. Previous versions of Visual C++ are not supported. Microsoft Visual Basic .NET 2005 for creating custom forms. It also supports Microsoft

Visual Basic .NET 2003 and Microsoft Visual Basic 6.

Intel Fortran 9.0 or 9.1 for creating Fortran procedures. This is unchanged from Aspen Chromatography 2006.

(44)

Touched variables always shown in black

If you change the value of a variable from its default, the variable value color changes from blue to black. In previous versions, if you changed the variable value back to its default, it would be displayed in blue.

In Aspen Chromatography 2006.5, the variable now remains displayed in black to show that you have changed the value, even though the value is equal to the default. The value reverts to blue only if you right click the value and click Reset to Default.

This change makes it easier to see all values that you have deliberately entered.

Compatibility Notes

The following lists and describes compatibility notes and issues for release 2006.5: You can install and use Aspen Chromatography 2006.5 at the same time as 2004.1 and other previous versions of Aspen Chromatography. However, observe the following compatibility issues when upgrading your existing simulations to Version 2006.5:

The ImpEuler (11.), VSIE (11.1) and Gear (11.1) integrators were old implementations that have been superseded by the Implicit Euler and Gear integrators that were

introduced in the 12.1 release. They were included in the 12.1, 2004, and 2004.1 versions to give time for transition of existing simulations to the new integrators. These integrators have been withdrawn from version 2006 and later. If you load a simulation that uses one of these integrators, it automatically switches to the equivalent newer integrator, and selects option- and tolerance- values that match the old integrator as closely as possible.

Aspen Chromatography Language (.cra) files generated using previous versions of Aspen Chromatography are compatible with Version 2006.5. You may see some warning messages when loading .cra files created with previous versions. This is a result of some solver options that have become obsolete or have been renamed. Saving the file in Aspen Chromatography 2006.5 eliminates these warnings.

Aspen Chromatography Document (.crb) files exported from previous versions Aspen Chromatography cannot be loaded in Version 2006.5. Load these files into the previous version and export them as .cra files, which can then be loaded into Version 2006.5.
