Overpressure protection objective:

Pressure relief devices (PRDs) protect equipment or piping from overpressure and low pressure hazards. The PRD operates by opening at a designated set pressure and by relieving the excess flowrate so that the pressure in the equipment or piping is maintained within its design conditions. If the PRD and its associated piping are not designed to relieve the excess flowrate or if the PRD fails to function on demand, there is a potential to overpressure and result in a loss of containment. In case of a loss of containment of flammable or toxic material, there is a potential for major accidents including vapor cloud explosions, fires or toxic exposure.

Course outline:

In this course, the participants will be guided on the overpressure protection design principles and design requirements. This course is designed to provide a focused guidance on the relief system design adequacy reviews. The course content includes analysis of overpressure scenarios, simple examples on the relief load calculations and relief device sizing. At the end of the course, the participants will have a knowledge and awareness on the fundamentals and first principles associated with the

• Overpressure protection design philosophy
• Overpressure protection design adequacy analyses
• Ability to identify credible overpressure scenarios
• Ability to understand the relief load calculations and relief device sizing

Who should attend?

Engineers involved in the Management of Change (MOC) reviews, process design and projects would greatly benefit by attending this course. In general, the course would be useful to process engineers, process designers, process safety engineers, project engineers from beginner to intermediate level.

Prerequisites:

Engineering background with a basic understanding on overpressure protection design requirements
