Physical and Thermodynamic data of a chemical component has a profound impact on the design and operation of a unit operation in a process industry. PRO/II uses component data stored in component data libraries within database files. In the past, users prepared data using older programs (REGRESS and DATAPREP) that now are obsolete. The Thermodynamic Data Manager (TDM) replaces their functionality. Using TDM, users can:
Build custom libraries containing pure component data, as well as unary and binary thermodynamic parameters.
Generate and display a variety of temperature-dependent graphical plots of tabulated data results.
Create, use, and maintain multiple databanks.
Calculate Regression data
Integration of the current version of PRO/II with the Thermodynamic Data Manager provides the following advantages to all PRO/II users.
PRO/II can access data from both TDM-defined libraries and (the older) edlib.lb.
Because of the new naming conventions introduced with TDM, several versions of a library may co-exist in the same directory.
TDM has a graphical User Interface that offers different modes of operation to facilitate defining new libraries and databanks.
TDM replaces the functionality of REGRESS and DATAPREP (now obsolete).
Component properties that are extracted from password protected user-defined libraries will be printed as ”PROT” in the output report.
Component properties that are extracted from password protected libraries will be shown as ”PROT” in PRO/II GUI.
In keyword input files, the newly added libraries and databank names in TDM can be recognized by Library Name:Databank Name.
The Component Selection and Thermodynamic Data - Databank Search Order dialog boxes allow viewing the new TDM libraries as well as existing libraries and databank names. Users can select and add any displayed libraries to the current simulation. For components with multiple databank search order and cascading ON, PRO/II will print ”PROT” in the entire row (of Fixed Properties and Temperature dependant Properties Windows) even if one of the property is from a password protected library.
Note: Refer to the Thermodynamic Data Manager User Guide for a detailed explanation of its functionality and operation.
