This Flares and Relief Systems virtual training course provides a comprehensive overview of relief and flare systems for oil & gas processing facilities. This EuroMaTech virtual 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
  • Engineers responsible for designing relief and flare systems in oil and gas facilities
  • Operations Personnel responsible for operating relief and flare systems in oil and gas facilities
  • Maintenance Personnel responsible for the maintenance of relief and flare systems in oil and gas facilities

This EuroMaTech virtual training course will combine presentations with interactive practical exercises, supported by pre and post-test activities plus case studies and videos. Delegates will be encouraged to participate actively in relating the principles and concerns of flare and relief systems installed at their operating facility.


In industrial plants relief systems prevent equipment from catastrophic failure and uncontrolled release of equipment contents. Flare stacks are primarily used for burning off flammable gas released by pressure relief valves during unplanned over-pressuring of plant equipment. This Flares and Relief Systems virtual training course covers essential skills necessary for the safe and efficient design, operation and maintenance of these relief and flare systems by providing delegates with the knowledge, understanding and expertise to ensure a reliable operating processing facility.
