Flowsheeting:
What is a flowsheeet
Importance of flowsheet
Presentation of flowsheets
Types of PFD
Flowsheeting: (the 1st step in process design)
Special language conveying information.
It's a diagrammatic model of the process
The Flowsheet Importance.
Shows the arrangement of the equipment selected to
carry out the process.
Shows the streams concentrations, flow rates &
compositions.
Shows the operating conditions.
Used by operating personnel for the preparation of
operating manual and operator training.
Flowsheet Presentation:
Two forms for presentation
A. Block diagram
B. Pictorial Flow Sheet
A- Block diagram
When is it used? (process proposal for packaged steps)
Block diagram.
B-Pictorial Flow Sheet
Types of pictorial flowsheets:
1- Process flow diagram [PFD]
PFD
Qualitative
Combined
PFD
PFD
[Qualitative flow diagram for the manufacture of nitric acid by the
ammonia-oxidation process].
PFD [Combined flow diagram for the manufacture of nitric acid by
the ammonia-oxidation process]
