The course covers relief, flare and vent systems design. It describes why specific equipment like separators and heat exchangers require relief protection and how to determine the relief cases for these items. The various elements of the relief system, from relief valves through piping and headers to flare knock out drums and flare tips, are covered as are the methods for determining overall system and peak relief loads. The course also covers how plant depressuring systems are configured and some of the specialised design principles such as cold temperatures and acoustic vibration are critical to sound relief system design.
Course Level: Foundation / Skill Duration: 2 days Instructor: Phil Tudhope
Designed for you, if you are...
A facilities or process engineer, either a graduate or a more experienced technical professional looking to develop theoretical competence in relief and flare system design
A safety engineer who seeks to gain competence in the principles and practices of relief and flare system design
A project engineer or manager who seeks greater understanding of the principles of sound relief and flare system design
An operations engineer looking to deepen your knowledge of the design principles of the plants
How we build your confidence
The course links theory to application. It reinforces this through real industry examples and allows participants to practice the theory through worked examples as part of the sessions. The course is highly interactive and participants are encouraged to share their own experiences and problems to the benefit of all.
The benefits from attending
By the end of the course you will have a good understanding of how relief and depressuring systems are designed. You will appreciate the importance of establishing all relief cases that apply and how these are equipment-specific. You will know how to determine governing relief cases for the system and how to calculate peak relief system loads. You will have an introduction to how staggering and staging depressuring systems can lower peak loads and how important cold temperatures and acoustic vibration are in the system design. You will have gained this from seasoned professionals who have been involved directly with relief and flare system design and have real life experiences to offer not just textbook knowledge.
