Relief & Flair Systems

This Flares and Relief Systems training course provides a comprehensive overview of relief and flare systems for oil & gas processing facilities. This EuroMaTech training course begins with defining the need for pressure control (over and under pressure protection), continues with the key engineering and design aspects including code considerations and concludes with selecting and defining the components of a relief flare system. The material presented is applicable to onshore field production facilities, pipelines, gas plants, terminals and offshore production facilities.

Participants will develop the following competencies:

  • Understand the purposes of relief and flare systems and their importance in safe operations
  • Understand the causes of over-pressure and the ways to control or mitigate them
  • Appreciate the process engineering principles underpinning relief systems
  • Determining the set / relieving pressures to meet operational, safety, and code requirements
  • Selection and sizing of other key components of a relief / flare system
  • Defining the possible relief scenarios
  • Commonly used pressure relieving devices, selection and sizing
  • Operational considerations of maintenance, testing, certification, and disposal of fluids
  • Designing and operating relief and flare header systems considering fluid characteristics, service conditions, volumes, gas dispersion, and radiation

Day 5 : Selection and Sizing of Key Components

  • Safety and relief valve types,
  • Application and sizing of common relief devices
  • Selection and sizing of key components:
    • Knockout drums,
    • Seal drums,
    • Vent / flare stack,
    • Flare ignition systems

This training course uses both conventional and non-traditional techniques. It utilises small group and facilitated plenary discussions as well as instruction to explore key concepts, models, tools and techniques. Hands-on exercises and case studies are used to practice the application of knowledge and use of skills. Structured reviews provide the opportunity to consider how the learning can be applied to the delegates’ own work.
