Study Notes
Block Flow Diagram
- Block flow diagram shows a sequential flow scheme
Process Flow Diagram
- Shows the general flow of the process
- Uses symbols to represent major equipment
- Does not include minor details like instrumentation control loops
Pipe and Instrumentation Diagram (P&ID)
- Shows the interconnection of process equipment and the instrumentation used to control the process
- Instrument identification (tag numbers) use letters and numbers
- The first letter indicates which process variable is being measured
- The second letter stands for indicator
- The third letter stands for control
- Example: LIC 100 - Level Indicator Control
- Symbol AAH stands for Analyzer Alarm High
Remote Balloon Symbol
- Letters identifying the instrument are placed at the top of the balloon
- Numbers are placed at the bottom of the balloon
P&ID Legend
- Shows the meaning of the symbols used in the diagram
Mechanical Flow Diagram
- Shows metallurgy, line sizes, and flange ratings
Isometric Diagram (ISO)
- 3-D drawing
P&ID Revision
- Cross hatching denotes a revision
P&ID Key Functions
- Unique identification number
- Shows connections between instruments
- Shows instrument locations
- Describes instrument functions
