requires two types of data:
Network data define the
network configuration, exchanger mechanical data, economic parameters and other data which do not change with time.
Case data consist of measured
parameters, such as temperatures and flowrates, which change with each Case.
Data are entered in data entry windows
or in bulk from a spreadsheet. Data
entry windows are opened from menu items or by right-clicking on a unit or
stream on the PFD.
Many defaults are supplied and range and validation checks are performed during the data input.
Data are also subject to rigorous
checking for realism and consistency. Obvious errors such as negative
pressures are not allowed. Warnings are issued for data items that appear
to be unreasonable – for example, too few baffles, too tight tube
spacing. Data may be entered in a wide range of dimensional units.
Each window has a Help button which gives
information about the data requirements of that window.
The configuration of a network is defined in the
PFD drawing. Other data are entered in data entry windows.

You may define any number of
Cases for a Network.
Case Data include:
the data were gathered
exit temperatures and pressures
temperature specifications (optional)
ratios or product flowrates
exit temperatures or duties
product water content
temperature, duty or product rate and pressure
pressure or power and efficiency
stream conditions and properties:
gravity and UOPK or viscosity for hydrocarbon liquid or gas streams
distillation curve, gravity and lightends for assay streams
compositions for defined composition streams
Exporting Case Data
You can write Case data to an Excel spreadsheet.
There are two objectives to this:
- Check data trends graphically to identify
sources of data errors
- Create a spreadsheet
Case data will be written to the spreadsheet for every parameter which has a tag name or
a property identifier.
