Description

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 benefits from attending

• Develop a good understanding of how relief and depressuring systems are designed
• Appreciate the importance of establishing all relief cases that apply and how these are equipment-specific
• Determine governing relief cases for the system and calculate peak relief system loads
• Understand how staggering and staging depressuring systems can lower peak loads and the importance of cold temperatures and acoustic vibration in the system design
• Gain insights from a seasoned professional who has been involved directly with relief and flare system design and has real life experience to offer, not just textbook knowledge
