1. Flowsheeting: What is a flowsheeet Importance of flowsheet
Presentation of flowsheets
Types of PFD

2. 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.

3. Flowsheet Presentation:
Two forms for presentation
Block diagram
Pictorial Flow Sheet
A- Block diagram
When is it used? (process proposal for packaged steps)
Block diagram.

4. B-Pictorial Flow Sheet
Types of pictorial flowsheets:
1- Process flow diagram [PFD]
PFD
Qualitative
Combined
