    Study Notes

    P&ID vs PFD

    • The P&ID diagram includes more detail than the PFD.

    P&ID Details

    • Shows the details of equipment orientation, piping, instrumentation, and control systems.
    • Provides information about equipment orientation.

    Purpose of P&IDs

    • In operation, repair, and modification of the plant, P&IDs serve as a guide for operations, maintenance, and engineering staff.
    • During design and pre-construction phases, P&IDs facilitate communication among designers, engineers, and operators.
    • For field construction and inspection personnel during construction, P&IDs provide a detailed guide for installation and inspection.
    • After construction, P&IDs serve as a reference for plant operating and engineering staff.

    Control Loop Components

    • In Figure 7, the instrument that senses the tank level is not specified.
    • The level controller sends an electronic signal to the diaphragm-operated level control valve.
    • The instrument that records the tank level is not specified.
    • The control system indicated by the control lines in Figure 7 is a feedback control loop.

    P&ID Content

    • Typically includes information about equipment, piping, instrumentation, and control systems.
    • Does not typically show information about civil foundations or building layouts.
