This is due to an incorrect registry entry created by our update service. A script can be downloaded at this link that should prevent the window from being displayed when logging into a system.

A Microsoft security update installed on computers beginning on approximately October 13, 2009 can cause this issue. The problem occurs specifically after the installation of Microsoft SQL Server hotfixes or service packs.  The service is incapable of starting after the update is applied, and ProMax will not open. Please download the fix from our website using this link and execute it using an account with administrative privileges.

ProMax 3.0 will run on Windows 2000 (Professional or Server), Windows XP (Media Center, Professional or Home), Windows Server 2003 (x86 or x64), Windows Vista, or Windows Server 2008 operating systems. ProMax will run on the x64 version of Windows XP (SP2 is required), Windows Vista, and Windows Server 2008. ProMax is also compatible with the beta release of Windows 7 (build 7000). While we do not anticipate any incompatibilities with the official release of Windows 7, please contact us after the release date for verification. Support for Windows NT4 based systems was dropped in ProMax 2.0. BR&E expects that future major releases of ProMax will not support Windows 2000 since support for this platform has been terminated by Microsoft. ProMax requires Microsoft Data Access Components (MDAC) 2.8 SP1. For all operating systems except Windows 2000, MDAC 2.8 SP1 can be obtained by applying the latest service pack (where applicable). Windows 2000 requires MDAC to be applied through a separate download from Microsoft. The MDAC Component Checker utility, which is available from http://www.microsoft.com/downloads, can be used to determine the version of MDAC installed on a system. MDAC must be installed prior to installing ProMax. ProMax requires a minimum of 512 MB of memory.

Visio 2002, Visio 2003 and Visio 2007. See the ProMax release notes for specific information on service packs and hotfix requirements. ProMax is compatible with both Professional and Standard editions of Visio.

ProMax has been tested with Excel 2000 and later.

Yes, ProMax has been tested with Windows 2000 Server and Windows 2003 Server Terminal Services. Using ProMax with Terminal Services requires a network license for ProMax.

At this time the only available help for ProMax is the online help file. We have not determined if printed documentation will be made available in the future. You may copy the ProMax.chm file to systems where ProMax is not installed if you need access to ProMax help. You can also print the entire ProMax help file, or only certain sections of it, as desired.

We currently do not anticipate having an automated method to perform this conversion. Please send the files to support@bre.com and we will manually convert them for you.

This problem is due to a timeout that occurs between ProMax and its internal database. To remedy this problem, increase the default timeout for this process. BR&E has created a VBScript program that can be used to increase the timeout. Simply download the program from our website using this link and execute it using an account with administrative privileges. A message box will be displayed once the timeout has been successfully increased. By default, the timeout will be changed to 60 seconds. This value can be changed using a “/timeout:” command line option if required. While we do not anticipate this to be a common problem, some users, especially those with limited hardware resources may experience this timeout. Additionally, systems with several running programs may also experience this error.

This error is due to a communication failure between ProMax and its database engine. It may simply result from the fact that the database service has stopped running. Restarting a service will require an account that has administrative privileges or a system reboot. To restart a stopped database engine without rebooting, the command net start mssql$bryanres can be entered in the Start->Run dialog or in a command prompt window. The command prompt window is usually preferred because the progress of the start and any associated errors will be visible. Alternatively, the command services.msc can be executed in the Start->Run dialog. This will start a Microsoft Management Console dialog listing the services installed on the system. The service SQL Server (BRYANRES) can be located and started by right clicking on the service name. Another common cause of this failure results from failure to reboot the system when requested during the installation process. If the ProMax installer indicates a reboot is required, this reboot is not optional and must be performed before ProMax will execute properly.

Microsoft SQL Server Express fails to install on a Windows XP SP3 operating system during updating of MSXML 6.

Unfortunately, several common antivirus programs over aggressively indicate a false positive for viruses, especially in the file reg2.exe. This program is actually supplied by a third party vendor, and the application is of the type that can frequently cause this false indication. Two antivirus programs that we are familiar with that indicate this false positive are AVG and ZoneAlarm. Our supplier is working with these (and other) antivirus vendors to white-list these files so they are not falsely flagged in the future. In order to install and run ProMax, you will need to disable virus scanning on this particular file. You also will likely need to disable the antivirus program on the reg2.exe file in the %ProgramFiles%\Bryan Research & Engineering Inc\ProMax3 folder after the installation is completed to prevent the antivirus software from relocating the file to its quarantine folder.

If your system experiences these failures after Microsoft SQL Server Express is installed, the problem is likely due to some issues with Microsoft Windows XP/SP2 that have been addressed in SP3. If you are not in a position to upgrade to SP3, Microsoft has created two hotfixes that can be applied to SP2 systems to fix this problem. The hotfixes may be downloaded from http://support.microsoft.com/kb/921337 and http://support.microsoft.com/kb/943232. Both must be applied.

In order to restart the system, you may need to boot the system in safe mode. After booting in safe mode, the two hotfixes can be applied.

The errors described here apply to systems that exhibit this particular failure during or after the SQL Server Express installation and before the ProMax installation itself has started. In fact, the error is seen on a system where an installation of SQL Server Express is made independently of ProMax by downloading the SQL Express product from the Microsoft download site.

For assistance with this or other similar problems, please contact us at support@bre.com.

In this release, the NetHASP.ini approach has been replaced by a web based console that configures the HASP runtime. The web based application is called the HASP Admin Control Center. The configuration is performed using http protocol on port 1947. To access the configuration section, open your web browser and navigate to the location http://localhost:1947. Click Configuration under Administrative Options followed by the Access to Remote License Managers tab. On that page, use the Specify Search Parameters to enter either the IP address or the hostname of the system with the network key. The new SRM driver must also be installed on the system with the network key.

The Security Device number is the 4 (or 5 on some NetHASP keys) digit number engraved into the device (NOT the number on the printed label).

The TZ environment variable may not be set correctly. Contact BR&E support for security device update instructions to remove the error. We can also assist in checking the TZ environment variable which was automatically specified when TSWEET/PROSIM was installed. If security violation 10 occurs when switching the security device between computers, the time and date may not be set correctly on one of the computers.

You must configure the NetHASP.INI file installed in %ProgramFiles%\Bryan Research & Engineering Inc\ProMax1 to be able to locate the NetHASP License Manager (LM). In general, you should set the value of NH_SERVER_ADDR in the [NH_TCPIP] section to the IP address or DNS name of the LM. A separate NetHASP.INI file must be configured for PROSIM/TSWEET. Unlike PROSIM/TSWEET, ProMax uses Windows sockets to access the LM where PROSIM/TSWEET use NetBIOS over TCP/IP (NetBT). This will provide for much simpler configuration for most scenarios.

Provided the security key is attached, this error is usually caused by a problem with the HASP SRM device driver installation. In order to solve this problem, you will need the command line utility for HASP driver installation. This utility is located on the ProMax DVD distribution. If you do not have access to this DVD, you may download it from the Aladdin website. You will need to download the “HASP SRM Run-time Command-line installation”. Do not use the GUI based installation as it does not offer the necessary functionality.

Note: If the last number in error is something different than above, contact BR&E as the error is likely related to some other issue.

The following steps will allow the driver to be reinstalled:

1. Obtain the ProMax distribution DVD or download the driver from the Aladdin website. If downloaded from the website you will need to uncompress the ZIP file to a temporary folder. This folder may be removed once this procedure is completed.

2. Click Start->Run in Windows and select the Browse… button. Navigate to the download folder or to the HASP & NetHASP\Driver\CmdLine folder on the DVD.

3. Select the haspdinst (or haspdinst.exe) program for execution.

4. Before clicking the OK button to execute the program, append the command line option -fremove to the end of the command line. Be sure to include a space between the end of the program name and the -fremove option. Do not remove any double quotes that may be surrounding the path to the program. If double quotes are present, the –fremove option should be placed after the closing double quotes with an intervening space.

5. If requested to reboot the system, reboot the system at this time.

6. Click Start->Run in Windows and select the Browse… button. Navigate to the download folder or to the HASP & NetHASP\Driver\CmdLine folder on the DVD.

7. Select the haspdinst (or haspdinst.exe) program for execution.

8. Before clicking the OK button to execute the program, append the command line option –i to the end of the command line. Follow the same guidelines as in step 4 above concerning the space requirement and the double quotes.

9. If requested to reboot the system, reboot the system at this time.

After following this procedure, the program should locate the security key. If you continue to have problems with the device, please contact BR&E technical support at support@bre.com.

We have found this problem to usually be related to firewall settings. The newest Aladdin software requires that port 1947 be excluded from firewall blocking for both TCP and UDP access. If you are using some sort of third party firewall package or antivirus program that performs blocking, you will need to open this port. After opening this port, you will need to reboot your system. Simply restarting the Aladdin hasplms service will not usually fix the problem.

1. Change the default content and order of stream properties displayed and reported by ProMax.
2. Change the default composition bases displayed and reported for a stream by ProMax.
3. Change the properties that are displayed in heat exchanger and distillation column internals.
4. Change the properties that are displayed in process stream properties tooltips.
5. Change the default display and reporting precision.
6. Change the default unit set for newly created projects.
7. Change the default gauge pressure setting for newly created projects.
8. Change the default percent/fraction setting for newly created projects.
9. Add user defined unit sets.
10. Change the default atmospheric pressure, acceleration of gravity, and reference (e.g., standard) pressure and temperature for newly created projects.

The Options.xml file location is dependent on the installation drive and language of the operating system. You can find the system wide Options.xml file in the application data folder under %AllUsersProfile%. The string %AllUsersProfile% represents a language independent environment variable for the common profile used by all users of a computer. Simply type the string %AllUsersProfile% into the address field of Windows Explorer to change to the proper folder. The Options.xml file is in a hidden folder in the %AllUsersProfile% folder. The name of that folder is also dependent on the language of the operating system. You can determine the name of this folder for your particular system by inspecting the last folder name in the %AppData% environment variable. Within the hidden folder, you will find a Bryan Research & Engineering Inc folder that contains Options.xml. For example, consider the following which is typical of an English language system:

AllUsersProfile=C:\Documents and Settings\All Users
AppData = C:\Documents and Settings\SomeUserName\Application Data

For this system, Options.xml would be located in C:\Documents and Settings\All Users\Application Data\Bryan Research & Engineering Inc\ProMax3\Data. When modifying the Options.xml file, you must keep in mind that future releases of the program will supply new versions of Options.xml. Any changes made to Options.xml must be manually incorporated in future files. The ProMax installation program will create a backup of Options.xml to prevent overwriting your modifications.

To provide each user with their own Options.xml, copy the Options.xml from the standard location to %AppData%\Bryan Research & Engineering Inc\ProMax3\Data. Each user can then make their own changes to Options.xml independently of other users on the same system. This is typically useful on shared systems used by more than a single user (e.g., a university environment).

See http://www.w3c.org/xml for information concerning XML. There are also many books published on XML available at virtually any bookstore containing computer related books.

Many XML editors are available for use. However, our configurable XML files for ProMax can be edited with Notepad if you do not have another editor.

In Options.xml, change the text of the node //ProMax/UnitSets/Default to the name of the desired unit set.

The units for a particular type of unit (e.g., length) are defined in the Options.xml file for each unit set available in ProMax. Simply locate the type of unit that is to be altered in the respective unit set. Change the text content of the XML node to the desired string. Note that unit strings in ProMax are case sensitive.

All unit sets are defined in the Options.xml file. To add a unit set, BR&E recommends that you copy and paste an entire existing unit set that is closest to the desired units. Change the name of the unit set to a name that does not conflict with an existing unit set and change the unit strings in the elements of the unit set to the desired values. You can make the new unit set the default by changing the text of the node //ProMax/UnitSets/Default to the name of the new set.

In Options.xml, change the //ProMax/ReportOptions/Paper node text from “A” (letter) to “A4” (without quotes). You also will likely want to change the default Visio template from a letter size based template to an A4 size based template. This is accomplished by changing the //ProMax/ProjectTemplate node text to Project-A4.vst.

Yes, these values are changed through Options.xml in the //ProMax/DisplayOptions/PStream/Properties and //ProMax/ReportOptions/PStream/Properties nodes, respectively. Simply order these items or add additional content as desired. Changes made in the Options.xml file affect newly created projects and projects that have not been customized for a specific property set.

Change the entries in the //ProMax/DisplayOptions/Tooltips of Options.xml to the desired content.

If this error occurs during startup, the likely reason is Microsoft Visio is not installed on the system or the system does not meet minimum version requirements for Visio. ProMax supports Visio 2002/2003/2007 Professional or Standard. See the ProMax release notes for further information and requirements concerning service packs and hotfixes. Ensure that Visio will run without error outside of ProMax before attempting to start ProMax.

If this error occurs during execution of a ProMax solver or specifier, is is likely that your computer is missing the Microsoft Windows script control or other scripting components. Normally, these components are bundled with the operating system for Windows 2000 and Windows XP. However, some software will remove these components when the software is removed from the computer. For these systems the scripting control will require manual reinstallation.

Please contact BR&E if you need assistance with this error.

Delete the folder %AppData%\Microsoft\Crypto and its contents from the system using the affected user account. The operating system will regenerate the folder as needed.

In general, this problem indicates missing, misconfigured, or outdated Windows components on the computer, or a computer that does not meet the minimum software requirements. BR&E has fully tested its installation distribution on various platform combinations to ensure that we deliver the proper components required by ProMax. Unless an error was indicated during installation of ProMax, this problem is likely due to external problems, not with ProMax itself. ProMax requires many operating system components and features to properly execute. The absence or failure of any one of these components may cause this problem.

This is a Microsoft issue that requires the Microsoft hotfix KB835732. To resolve the problem, log on as Administrator, and repair the ProMax installation from the Control Panel, Add/Remove Programs. To install the Microsoft hotfix, run Windows Update from the Start menu or download the hotfix from http://download.microsoft.com. The minimum requirement to run ProMax on Windows 2000 is Service Pack 3 and the KB835732 hotfix. However, installing recommended critical updates can help keep your computer up-to-date and secure.

To restore the menus and toolbars to their original status, delete the files %AppData%\Bryan Research & Engineering Inc\ProMax3\Data\LCID\*.vsu from your system. The value LCID represents the locale identifier for your language and location. A value of 1033 signifies U.S. English. ProMax will reconstruct these files as needed.

Using the Stencils (Visio 2002) or Shapes (Visio 2003) menu item located in the File menu, browse to the install location of the stencils (%ProgramFiles%\Bryan Research & Engineering Inc\ProMax3\Templates) and add all *.vss files as stencils. In Visio 2007 click the Shapes item in the File menu and the stencils appear in the menu to the right. Select the stencils to be added.”

Separators, mixers and distillation columns will allow multiple inlet streams to be attached to an inlet connection point.

Depending on the routing of a stream connected to a block, the location of the stream text or name can be obscured. You can easily move the location of a stream name by selecting the yellow diamond with the cursor and dragging the text to a new position. Obviously if you move the label, you must assume the responsibility for repositioning it in a location that is proper in the context of the drawing. For more complicated drawings, it may be advantageous to reduce the point size of the text associated with a block or stream to provide more room for drawing entities. Alternatively, you can right click on the block and use the “Shape->Bring to front” menu item to have a block name superimposed over a stream.

Once a particular message has been viewed in the Update Service, you can use the Update Manager to hide the message. Hiding a particular message does not prevent future messages concerning updates and other information from being displayed. The Update Manager is located in the Start menu with the ProMax items. To hide messages, start the Software Manager and specify that the messages are not to be shown again. You can use the Software Manager to restore hidden messages at a future time.

Please ensure your operating system is current with regard to hotfixes and service packs from Microsoft. This issue has been fixed by Microsoft.

To import or export data to and from Excel, you must first create an OLE embedded Excel Workbook within ProMax using the “Add Excel Workbook” in the ProMax menu. This Workbook is then saved within the structure of the ProMax pmx project file along with the remaining project data. Once this Workbook is added, you export or import data as follows:

• Select the data cell that you wish to export or import.
• Next, right click the cell and select the first item from the context menu that appears. The Excel Export/Import Utility box will open. This box will float over both ProMax and Excel. (This right clicking also allows access to dialogs that remove Import/Export links.)
• Next, select the Excel cell(s) where you wish to place the data link.
• Last, explicitly confirm the desired type of import or export and close the utility.

Most single value items can be either exported or imported depending on their context within a project. At this time, composition data from a stream can only be exported to Excel. Be sure to select enough Excel cells to capture all exported data, or truncation of latter data will occur.

Use the ProMax Solver under the Excel Tools menu to design and converge flowsheet data. Beware that the Excel Solver (ALT+T+V) is not linked to ProMax and will not cause the ProMax Engine to resolve the flowsheet.

Current or “green“ streams can be copied and pasted to the same flowsheet with specifications or current information intact. To copy a stream to a different flowsheet, you will have to Copy and Paste the composition and conditions. Simply copying and pasting blocks or a group of blocks from one flowsheet to another in the same or different Projects copies only the blocks and streams without any of the specifications. A new feature in ProMax 3.0 allows you to Export a ProMax Project and then Append that Project to another Project. The Exporting and Appending feature in effect accomplishes the copy and paste with specifications intact. Among other uses, this procedure can be used to create templates of common processes such as dehydration, amine sweetening, refrigeration, etc. for appending to other Projects. See ProMax Help for detailed information on Exporting and Appending ProMax Projects.

You may create your own process shapes for all operations except multi-sided exchangers and distillation columns using the Shape Converter in the ProMax Property Stencil. In effect the Shape Converter allows you to convert an ordinary Visio shape into a ProMax block. The new block can be saved for future use. See ProMax Help for further information.

You can disable the simple hydrate and other freeze type checks from occurring within the streams and blocks of all flowsheets associated with an environment by unchecking the “Check Freeze Out” button on the Options page of the environment dialog. You may also adjust how close to freeze conditions you actually must be before a warning is issued by changing the temperature delta value. Disabling this check does not affect freeze out calculations in Analysis objects.

The Propagation Terminal is used in a closed loop situation where no material is entering or exiting the system (e.g., refrigeration loop). It is used to prevent specified properties from propagating both forward and reverse in the closed loop.

For simple cases the UA or Approach Temperature can be specified directly in a cross-exchanger. Note that this must be a cross-exchanger block because the UA, LMTD, and Approach Temperature specifications are not available for two single-sided exchangers linked by an Energy Stream. For more complicated configurations with interconnected cross exchangers and recycles, a simple solver can be used to find the value of duty or temperature in a cross exchanger to achieve the desired UA or Approach Temperature. See ProMax Help for detailed examples describing the setup of UA or Approach Temperature solvers.

ProMax more rigorously handles the presence of the air in the testing than was done in PROSIM. In most cases, the results are within the error of the program.

While there are many valid locations for this specification to be made, the most common location is usually in the outlet of the Make-Up/Blow-Down operation. For typical amine or glycol dehydration units, it is also legal to specify the circulation rate in any lean stream between the regenerator reboiler and the absorber.

Yes, the ProMax Scenario Tool, which is an add-in for Microsoft® Excel (2000 or greater), allows you to easily and automatically solve a number of ProMax projects with various conditions. Some examples of the use of the Scenario Tool might be 1) Perturbing inlet conditions and compositions, 2) Adjusting equipment specifications, or 3) Simulating historic plant data. Please refer to ProMax Help for detailed information on using the Scenario Tool.

ProMax can run as an in-process OLE automation server within any OLE automation client. A common use is to run ProMax within Excel to perform utility functions such as property calculation and flash calculation. At this time, the automation interfaces are undocumented. However, with some assistance from BR&E and the VBA object browser, an experienced VBA programmer can likely accomplish some fundamental tasks. Please contact BR&E for assistance with a particular project.

The ProMax Property Stencil includes a Membrane Tool which is a block that simulates an asynchronous vapor phase separation. This simplified model operates irrespective of equipment geometry. The tool provides the ability to perform a separation based on fixed total area, or to solve for the area given desired separation constraints. Permeability data (selectivity) is dependent on the polymer employed and its thickness. Example values from patent literature are provided in the Edit Permeability dialog for your convenience, however, consult literature or vendor references for final designs. See ProMax Help for detailed information on the Membrane Tool.

For glycol dehydration, you may use either the Peng-Robinson or SRK property package. ProMax contains the modeling technology to accurately predict dehydration and hydrocarbon solubility (including BTEX) in these systems using either package. This technology is inherited from PROSIM, which has a long published and proven history for accurately modeling these systems. If high amounts of CO2 or H2S are present, you may obtain slightly better solubility predictions if the Peng-Robinson Polar or SRK Polar packages are used. In most cases, using the polar versions of the package will provide identical results but will take longer to execute.

When methanol is present in an aqueous system, you must use either the Peng-Robinson Polar or SRK Polar package. The standard Peng-Robinson and SRK packages will not accurately predict the VLE, VLLE, or hydrate suppression for these systems. ProMax includes improvements over PROSIM in modeling these systems, especially when high methanol to water molar ratios exist.

No, the glycol composition is determined by the regenerator performance. In an amine system, the ratio of amine to water is to be held constant resulting in different make-up rates for amine and water. The fact that two separate make-up flows are present in the amine system requires the additional specification to satisfy the extra degree of freedom. However, the make-up composition of glycol and amine must be specified either in the make-up stream or in the Make-Up/Blow-Down block “Makeup Bulk Composition” column. (A typical make-up composition for TEG is 99.9 wt % TEG and 0.1 wt % water). See ProMax help for details on specifying the Make-Up/Blow-Down.

To obtain accurate results for any amine application, the Property Package must be set to one of the electrolytic models. Amine Sweetening or Electrolytic ELR should be used for most applications. Either SRK or PR may be used for the vapor phase. Electrolytic Kent-Eisenberg calculates more quickly than the other models, but should be used for preliminary results only.

To obtain accurate results for sour water stripping applications, use Electrolytic ELR as the Property Package.

Set the absorber Flash Type to LLE and leave the Column Type parameter set to Equilibrium (TSWEET Kinetics does not apply to liquid treating). A liquid-liquid treater will rarely have more that 2 or 3 ideal stages.

In an amine unit simulation, you must set the weight percent amine in the Make-Up/Blow-Down block dialog Process Data tab. The amine concentration is specified in the Target Outlet Composition column. Water is specified as 100% in the Makeup Bulk Composition column. Other components such as carbon dioxide and hydrogen sulfide should NOT be entered in this table. See ProMax help for further information on the Make-Up/Blow-Down block specifications.

Rich loading cannot be specified directly as in TSWEET. Rich loading may be achieved using a Simple Solver to manipulate a parameter such as lean amine circulation rate to achieve the desired rich loading. See ProMax Help and ProMax Examples for further information on using a Simple Solver to achieve a certain rich amine loading.

A separate exchanger representing the steam condensation side must be set up and linked to the reboiler using an energy stream. Then the steam rate may be set directly or a Specifier may be used to achieve a desired lb steam per gallon amine circulation specification. See ProMax Help and Examples for further information.

Yes, you can use an Amine Analysis in any aqueous liquid stream to determine the CO2 and H2S loading in gr/gal, scf/gal, and mol/mol. The Amine Analysis also calculates the Total Acid Gas Loading in mol/mol, the pH, and the Molarity.

Yes, either in the Amine Analysis (process stream Analysis tab), or in the stream Full Species Information. The Full Species Information is accessed by clicking the “Ionic Info…” button at bottom left of the stream Composition tab. The pH property is reported as p[H+].

Yes, the effects of adding acid to the amine solution to protonate the amine can be simulated. Although any of a number of acids (e.g. phosphoric, hydrochloric, acetic, sulfuric) may be used to protonate the amine and enhance stripping, phosphoric acid (H3PO4) is recommended in the ProMax simulation because equilibrium and plant data are available to verify results

To model an amine reclaimer, a portion of the lean amine from the reboiler is split off, heated to simulate the reclaimer, and a Divider is used to split off a specified amount of amine equivalent to the amount of degraded amine. The amount of degradation cannot be predicted by ProMax, but the reclaimer model can be used to determine the reclaimer duty and amount of required amine make-up. See the Simple DGA Sweetening Unit for an example utilizing a reclaimer on the stripper.

There are two ways to model a single stage contactor: 1) three phase Separator, or 2) two ideal stage Column with the efficiency set to 1% for all components on one of the stages. The Column approach must be used if you want to model a single stage contactor with less than 100% efficiency.

In the exchanger block dialog Process Data tab, click the Enable checkbox near the bottom. This will allow you to access to the Rating tab.

To rate an air cooled heat exchanger in ProMax, you must connect the heat exchanger to another heat exchanger side that contains air as the process fluid. (Single-sided exchangers cannot be rated in ProMax.) Usually the inlet and outlet temperatures are specified for this air side and ProMax computes the flow rate from the required duty. If nitrogen and oxygen are not present in the environment for the flowsheet, you may wish to add another flowsheet that contains nitrogen and oxygen and connect a heat exchanger in this flowsheet to the air cooler through a cross flowsheet connector.

Within the heat Exchanger Rating information, very top line under the “Tubes” item asks for the Service, and the options are Supply and Demand. If the Hot fluid is flowing through the tube side, select Supply. If the Cold fluid is going through the tubes, select Demand. This selection follows the Second law of Thermodynamics, that heat always flows from a higher temperature level to a lower temperature level.

In the Separator block dialog Process Data tab, click the checkbox next to “Include Separator Sizing”. This will allow access to the Sizing tab. (If the “Include Separator Sizing” parameter is not visible, scroll down to the end of the Process Data parameters.)

Word 2000 does not support compression used by default for the process flow diagram creation. To disable the compression, change the Compressed attribute in Options.xml of the //ProMax/ReportOptions/Layout/FlowsheetDrawing node for each type of paper you utilize to “false” (without quotes).

ProMax requires version 1.7 of RTF. Most of these packages are only compatible with earlier versions of RTF. Microsoft provides a Word Viewer program that is freely available from the Internet if you do not have Microsoft Word.

The Report Navigator is software that is part of the ProMax package and is only available on systems that have a legal copy of ProMax installed. Installation and use of ProMax is governed by your license agreement.
