2.3. Definition of the Calculation Conditions
3.1.1. In the cell [A1], eql or rcl must be
eql: calculation of an equilibrium
rcl: inverse calculation of an equilibrium state
3.1.2. Temperature and pressure have to given in the cells [B2]
3.1.3. Thermodynamic system must be contains at last one phase.
The phases are defined in separate sheets.
The sheet names of the phases are written in the cells [B4], [C4], [D4] .
. . [I4].
Maximum 8 Phases are permitted.
When a compound exists as pure substance, a separate sheet is not
necessary, you can enter in the column for ac [F]
In the Cell [A1] in the each sheet, the state must be given, (g)
or (l) or (s).
Phase sheet must be end EOT
3.1.4. All errors are written in the message window
3.2. Behaviour of the MS Excel
When MS Excel was not open by user and Process Calculator is
executed using parameters,
then Process Calculator opens MS Excel in background.
The calculation results are written in the
MS Excel file, the file is saved und MS Excel will be closed.
When MS Excel was already open by user, then Process
Calculator shows the given MS Excel file in the active MS Excel
The results are written in the MS Excel file but the file is not saved
When you are going to close MS Excel, you will be asked by MS Excel, if
you want to save the changes.
3.2.1. MS Excel does usually not permit more than one access at the
When you edit a cell in a sheet (when a cell gets
focus), the application Process Calculator for MS Excel
(XProCalc.exe) can not read or write in the MS Excel file. When you are
editing a cell the MS Excel file and execute XProCalc.exe, then an error
can be occurred.
When automatic save in every (i.e. 10 minutes) is activated in MS Excel
(MS Excel Menu Extras -> Options) , read and write is not possible while
You can see error massage, that the data exchange not possible.
3.2.2. When more than one MS Excel applications run.
Several MS Excel Versions ore Multiple Document Application. You can
in a MS Excel Window more than one MS Excel File open. Following picture
shows two MS Excel windows. XProCalc.exe can access to only one instance
of the MS Excel windows. You can see in the Task Manager of the MS Windows, how many MS Excel
windows are open.
Execute Process Calculator for MS Excel
(XProCalc.exe) and press button to show the MS Excel, you can see, which MS
Excel Window (instance) is accessed by Process Calculator for MS Excel.
The MS Excel window can be shown, even if the window was hidden.
3.2.3. When no any MS Excel window is open
When you execute XProCalc.exe using parameter as following,
-x:C:\AsTher\projects\Furnace.xls -c: FurnCond
and no any MS Excel window is open, XProCalc.exe execs MS Excel in
the background, you can not see
You can avoid the problem, when you execute MS Excel before
XProCalc.exe is executed.
3.3. when the mass-conservation is not possible, the calculation will
be terminated. For example, if elementary
oxygen (O2 (g) or O (g) ) does not exist ina system
consisting of the elements H and O, when only the substances H2(g) and
H2O(l) for the calculation selected, the calculation is impossible for 1
bar and 1000 °C. Calculations are broken .
To avoid this, it is
recommended to include first time all possible substances into the
calculation. You can deselect substances from the calculation system,
when it is secure, that the deselected substances can not be exist in
Height number of substances causes long calculation time and
imprecision. The thermodynamic data set of the rare substances
may be some times approximated. It is also difficult to overview.
Low number of substances causes fast calculation time. It is easy to
overview. But the calculation may be incorrect, because the
system may be not complete.
An optimum is often individual to decide.
3.4. Error messages related to operations system may occur
due to excessively high values of the free energy of a substance, so
that the processor can not interpret the value. In this case, please
check the thermodynamic data set.
3.5. Two reaction systems with high different quantities may produce
Example, when a system consisting of Fe, Cl2, FeCl2, H2O,CO,CO2,N2,NO.
wherein one reaction system is consisting of Fe-Cl2-FeCl2 and the
other consisting of C-CO-H2O-N2-NO.
If the inputs of the calculation is 10000 mol FeCl2, 1 mol H2O and 1
mol N2, 0.1 mol C, and the precision is 0.01,
the calculation result may be incorrect for the system C-CO-H2O-N2-NO.
It is recommended to calculate in separate systems.
3.6. Pure Substances :
If a substance my be exists as a pure substance (and accordingly the
activity coefficient has been set to (1) in the a.c./f.c.- column,
please check after the calculation, whether:
- the info column shows the value 1,
- the amount of that substance is more than 1e-23 mol,
- the calculated value or the activity is nearly 1.
If not, those substances should be excluded from the calculation, e.g.
by setting the a.c.-value to 0.
3.7. An Obviously Erroneous Result (e.g. the formation of liquid Fe at 20
°C), although the calculation results keeps consistent.
This may happen, if the extrapolation is enabled and the extrapolated
data itself are unusable.
With the application Pure Substance, you can follow the course of the
free Enthalpy in graphic and table window in order to check the
validity range of the required dataset.
3.8. Erroneous calculation can be caused by the incomplete
definition of the system. The system can be influenced by mass of the gaseous
substances, although these substance can not take in any reaction. The
results of the calculation will be is different in a system consisting
of CaO, CaCO3, CO and N2, when the mass of N2 is different, although N2
does not react.
