Title: PRESSURE RELIEF BLOWDOWN & FLARE SYSTEMS
Start Date: 13 March 2023 End Date: 17 March 2023
Venue: Paris, France
Training will be held at any of the 5 star hotels. The exact venue will be informed once finalized.
Liquids should not be discharged directly to a vapor disposal system. Flare knockout drums and flares need to be large enough to handle emergency blowdowns. Drums should be provided with relief in the event of over pressure. Pressure relief valves must be provided where the potential exists for overpressure, or accumulated gases. Maintenance is important because valves are required to function properly. The most common operating problems are listed below.
- Failure to open at set pressure, because of plugging of the valve inlet or outlet, or because corrosion prevents proper operation of the disc holder and guides.
- Failure to reseat after popping open due to fouling, corrosion, or deposits on the seat or moving parts.
- Chattering and premature opening, because operating pressure is too close to the set point.
- Know how the air requirements for combustion are calculated and provided
- Understand the staging arrangements of flare systems and how this staging is achieved
- Recognize the various types of elevated flare tip and understand how they operate to achieve the necessary performance
- Be aware of the effects of radiation, noise and emissions on personnel and adjacent equipment
- Understand the need for and the methods of achieving adequate liquid knockout in flare systems
- Know how seal pots work and understand the options for seal water systems
- Be aware of the use of compressors in flare gas recovery systems and understand the potential economic savings which such a system can offer
- Understand the maintenance and repair needs of an efficient flare system
- Be aware of the recommendations of standard flare system specifications such as API 520/521.
Operations engineers, process engineers, operators, facility engineers, plant engineers, and Operations personnel who are involved in the use of the flare and/or who rely upon the flare system to safely dispose of unwanted releases.
Design engineers who are involved in the design, modification or repair of the flare system.

Note: Pre & Post Tests will be conducted
Case Studies, Group Exercises, Group Discussions, Last Day Review & Assessments will be carried out.
Define Management Consultancy & Training Certificate of course completion will be issued to all attendees.
A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions, and motivate everybody find the right answers. The delegates will also be encouraged to raise their own questions and to share in the development of the right answers using their own analysis and experiences. Tests of multiple-choice type will be made available on daily basis to examine the effectiveness of delivering the course.
6,250 US$ per participant for Public Training includes Materials/Handouts, tea/coffee breaks, refreshments & Buffet Lunch
