Basic Emergency Relief System Design

Preparing to use DIERS technology in your emergency relief system design but not sure where to start? Attend this instructor-led, 3-day course for an introduction to pressure relief safety design with Design Institute Relief Systems (DIERS) technology. This course is a first course in pressure safety relief design and a prerequisite to the advanced AIChE course (CH173) also presented by DIERS. Together the two DIERS courses form the basis of a solid fundamental understanding of pressure safety relief design.

This course introduces the concepts of DIERS liquid vapor disengagement technology, two phase vapor liquid flow through relief systems and techniques for reactive relief design. From state-of-the-art venting and flow technology to relief system piping, you’ll gain information that will be invaluable, whether you operate, design or manage chemical processes that require emergency overpressure relief devices.

Each participant receives the eBook: Guidelines for Pressure Relief and Effluent Handling Systems (published by CCPS and includes SC Lite computer code license).

Expect three, fast-moving days of learning enriched by course instruction, video presentations, example problems and homework. Attendees are required to bring a laptop to this course.

This course will be taught by two of the instructors listed below:

What You'll Learn:

  • An introduction to the broad topic of emergency relief system design

  • How to achieve compliance with established codes, standards and design practices in the broad area of emergency pressure relief and effluent containment.

  • How fluid flow models are used in pressure safety relief design

  • The requirements for relief system piping.

  • Conservative assumptions typically made to determine the required load for pressure relief systems

  • Where to obtain resources and references to guide further development as a skilled ERS engineer

  • The first steps to becoming proficient in the complex field of ERS design and evaluation

Who Should Attend:

This introductory course is designed to meet the needs of engineers responsible for operating, designing or managing chemical processes that require overpressure relief devices. It will also be beneficial to engineers seeking more information about state-of-the-art venting and flow technology and those responsible for the safe handling of the effluent from an emergency relief device.
