Piping and Pump Networls & Relief

This course is suitable for new or experienced users of CHEMCAD who are interested in steady-state and dynamic modeling of pumped piping networks and relief devices. This includes pipe specification, how and when to use nodes, pump curves, PID control, single- and two-phase relief from vessels, and relief header sizing.

In addition to the course presentations and simulations, participants will also receive PDF copies of all P&I Design publications, along with access to the 100+ simulations described in the books. These simulations draw on P&I Design’s extensive 38 years of experience in the field of Chemical Engineering.

 

This course takes place from 9:00 AM to 5:00 PM.

Agenda: 

  • Introduction
    Building a model - typical procedure with review of results and report building
    Pipe sizing, control valves, and orifice plates
    Setting up a sensitivity analysis

  • Flow-driven models
    Model a piping system and calculate pressure drop
    Model pumps with or without a pump curve
    Use controllers to fix pressure and determine flow

  • Pressure-driven models
    Flow-driven versus pressure-driven models
    Use nodes to create pressure-driven models
    Use nodes to determine distribution of flow across a network

  • Flow and pressure dynamics
    Benefits of dynamic modeling and how it differs from steady state
    Build a basic dynamic model and review results
    Using recycle streams - with caution
    Using dynamic hold-up in pipes

  • Control
    Specify a control valve to fail open/closed
    Specify a split-range control valve
    Revisit PID control basics, and set up a control loop

  • Emergency relief basics
    Investigate over-pressure scenarios - vent blocked
    Revisit pressure relief basics, and rate relief devices using sizing tool and UnitOp - single phase
    Vessel and vent flow models for two-phase relief
    Design relief devices - single-phase and two-phase relief
    Model relief into a header

  • Emergency relief dynamics
    Investigate relief scenarios dynamically
    Examples: dynamic vessel relief, multiple batch reactor, fire emergency relief, fire-induced runaway reactions, distillation column relief
