Wall Dynamics Tutorial for High-Pressure Systems

The wall dynamics approach is based on the fundamental heat transfer equation outlined in API Standard 521 Pressure-Relieving and Depressurizing Systems. In this presentation, see a demonstration of the wall segmentation method using Process Safety Office^® SuperChems™ and its advantages. This software allows the user to:

• Predict the fluid dynamics of equipment containing liquids, vapors, and
  multiphase flows with or without chemical reactions
• Specify equipment internals using a variety of materials of construction
• Connect multiple equipment and connect relief and process lines to the top and/or bottom of equipment
• Include incoming and outgoing fluid streams
• And more

Two case studies are included for demonstrating the application of the wall dynamics approach. Case study one shows how to model a pressure vessel where exposure to an open pool fire has been identified as a contingency of concern. Case study two demonstrates how to model a low-pressure atmospheric tank identified as exposed to thermal radiation, due to a nearby pool fire.
