|Getting Started with Analyzers
There are many new features for Analyzers 3.2. Let's examine just a few new ones...
This is the new default start up screen. There are some features you may recognize from version 2.0 but there are definitely some new features. The most notable feature is that the "Explorer" screen is no longer there. We found that this screen was not necessary. We have moved the icons for new objects to their own window.
We have also added a new feature called the object library. We have provided some example objects with the installation of the software. To use these object you simply need to drag them to the streams area. We will show you how to do this in a later tutorial.
We also allow you to create an object that can be used in any Analyzer document that you need to create.
Many times you will want to work in units that are more convenient than moles, centigrade and atmospheres. These are not the standard set of units for most industries. You will want to change them using the OLI Analyzers Units Manager.
Data bases are OLI’s store house of thermodynamic data. Not all the data is suitable for every calculation. Therefore the data is compartmentalized in to many databases. In addition, data service work provided by OLI Systems, Inc. may also be a database. You can find instructions for installing and loading private databases below:How to Load Databases
There is an architecture to using databases in the Analyzers. If you want a database to be used in all streams and calculations, you must specify the database at the topmost level of the software. The top level dialog is displayed below. To use a database in only a stream or calculation, specify the database only in that object. The PUBLIC database is automatically specified and can not be changed.
Click on the Chemistry menu item.
This will display the chemistry options. Select Model Options…
The currently loaded databases will be displayed as well as the current thermodynamic framework (AQ or MSE)
When the desired database is highlighted, click the right arrow to select it. We are also selecting the Corrosion Database for example purposes.
Databases have priority. If a species exists in both of these selected database, then only the thermodynamic properties found in the first database will be used. You can change the priority of the database by highlighting it and clicking the up button.
Click the down-arrow to reorder the list:
You can remove a database if it is not required. This does not delete the data from the program but makes it unavailable. Select the database and click the left arrow.
Click the left-arrow and the Corrosion databaes will not be used in this calcuation.
The database has been removed. Click the Apply button and then OK to continue.
Currently OLI Systems, Inc. only supplies user databases (formerly known as private databases) in the OLI/ESP format. This is not directly usable by the OLI/Analyzers. These databases are normally compressed using a program such as WinZip? . Please decompress (unzip) the file into a working folder. See Installing ESP Databases for more information.
You will then need to load and convert the supplied database. Fortunately there is a tool to do this for you. Please follow these steps:
Start the Analyzers
Select the Chemistry Menu Item
Select Model Options
You can load both Aqueous databases and MSE databases from the same screen. Click the Import Databank button.
If you know the exact location of the ESP "dic" file, you can enter the location directly. It is usually easier to browse for this file. Click the Browse button
Locate the folder that has the decompressed ESP format file.
The available database will be displayed. The DIC file (short for dictionary) is the file required. Click the file in the open dialog and then click the Open button.
The full path of the "Dic" file is displayed along with the display name of the database. You can rename this database if you desire. It is recommended that for most uses that the default name be used.
Click the Next button.
The process of converting and uploading the file starts.
If all the lines are checked, then click the Finish button
Your imported database is now ready for use. If your database was for the MSE framwork, as it is in this example, you will need to switch Thermodyanmic Frameworks to use the database. Click the drop-down arrow.
If your database is in the MSE framework, select MSE
The newly imported MSE framework database is displayed.
Click it to select it. Then click the right-arrow.
Click the OK button to continue.
The newly imported database is now being used as indicated in the Summary window.
Sometimes a user will want to remove a database from consideration. To do this locate the Databanks Tab via the Chemistry Menu Item > Model Options path.
There is no warning to make sure you want to do this. Be careful
Click the Unload Databank button
This removes the selected databank.
The database has been removed
