In order to have an effective depressurization & vapor relief system; you need to know how you can select, size & operate it. This training is applicable to pressure-relieving and vapor de-pressuring systems. The training course is applicable to petrochemical facilities, gas plants, liquefied natural gas (LNG) facilities, and oil and gas production facilities. Pressure vessels and other equipment require relief devices to provide overpressure protection to prevent conditions that may cause serious injuries to personnel, costly mechanical damage and environmental releases. The training course gives you specific detailed guidelines for evaluating a relief system, including determining the applicability of overpressure scenarios, required relief rates, and relief device capacity. Flare system calculations such as flare thermal radiation zone & purge gas rates is also included.
This training will highlight:
- Fundamentals of Pressure Relief Valve Design & Operation
- Overpressure Scenarios
- Selecting and designing disposal systems, including such component parts as piping, vessels
- Selection & design of the flares, and vent stacks
For many decades of the last century. Process vents and pressure relief flows were directed, individually or collectively, to the atmosphere unburned. Gases separated from produced oil were also vented to the atmosphere unburned. The custom of unburned venting began to change later when increased environmental awareness and safety concerns created the desire to convert vents to continuously burning flares.
By the end of this training, participants will learn to:
- Understand the importance of pressure relief systems and their key principles
- Select and size appropriate relief devices (e.g. Pressure safety valves)
- Calculate flare header thermal radiation zones & purge rates
- Understand the flare system equipment operations & maintenance
- Understand the zero flare principles
