About the course
This intensive course provides a comprehensive overview of relief and flare systems for oil and gas processing facilities. The course begins with the need for pressure control/overpressure protection, continues with the key engineering and design aspects including code considerations, and concludes with selecting and defining the components of a relief and flare system. The material of the course is applicable to onshore field production facilities, pipelines, gas plants, terminals, and offshore production facilities.
Designed For
Engineers and senior operating personnel responsible for designing, operating, and maintaining relief and flare systems in oil and gas facilities.
You will learn
  • Purposes of relief and flare systems and their importance in safe operations
