Course Description

This 5 days course presents a convenient overview of relief system details based on the full scope of API, ASME, and other code and specification requirements. It covers all aspects of relief flare systems from the emergency relief sources through the valving and flare network right to the stack and flare tip. Descriptions and design criteria will be outlined for flare tips, seals, stacks, knockout drums, header systems, relief valves, depressurization systems and basic hazard analysis. Alternative design methods will be also described with reference to the specific nature of relief and flare systems worldwide.

The flare, blowdown and pressure relief systems are the most important elements for emergency and operational discharge of flammable substances in the process facilities. Safety relief and flare systems control vapors and liquids that are released by pressure-relieving devices and blow-downs. Application of relief devices must comply with appropriate ASME Vessel Codes and API 520/521 standards. Design of relief devices must comply with applicable national codes and laws as well as the requirements of the insurance covering the plant or installation. 

Course Objectives

  • Identifying the types, features and application of flare systems
  • Determining the components and function of the relief systems and practice the sizing and installation of the relieving devices
  • Applying  an  in-depth  knowledge  and  skills  in  the  operation,  maintenance  and troubleshooting of flare, blowdown and pressure relief systems
  • Discussing product specification and identify the different types of flow measurement
  • Reviewing the various instrumentation and sensing devices used in flare, blowdown and pressure relief systems
  • Carrying out installation, troubleshooting and calibration of the control systems used in plant
  • Determining the applicable codes, standards and recommended practices for flare, blowdown and pressure relief systems
  • Acquiring knowledge on product storage and tanks and recognize the importance of product recovery
  • Evaluating the scope of waste heat recovery and explain its role in flare and pressure relief systems
  • Operating, maintaining and troubleshoot flare, blowdown and pressure relief system in a professional manner
