Introduction to Pressure Relief System Design [Webinar]

Pressure relieving systems are an integral part of any process facility, from offshore production platforms to petrochemical complexes, and usually provide the last line of defense against overpressure and loss of containment. Although ubiquitous, pressure relieving systems are not necessarily well understood by all chemical process engineers.

In this webinar, participants receive an introduction to the fundamentals of pressure relieving systems including causes of overpressure, determination of relief loads, methods of pressure relief, and how these concepts are tied together by applicable industry codes, standards, and practices.

In addition, we will provide insights into recent changes to API Standard 521, Pressure-Relieving and Depressurizing Systems and API Standard 520 Part II – Sizing, Selection, & Installation of Pressure Relieving Devices, Part II, Installation


This webinar will include:

  • The fundamentals of pressure relieving systems
  • Causes of overpressure
  • Determination of relief loads
  • Methods of pressure relief
  • Applicable industry codes, standards and practices
