Flare header sizing criteria
WebBackpressure and Gas Velocity are the major criteria governing the sizing of the flare header. The flare header size has to be large enough to prevent excessive back pressure on the plant safety valves and to limit gas velocity and noise to acceptable levels.

Flare header sizing criteria
Did you know?
WebConventional PRVs require the relief header back pressure (superimposed plus built-up) to be less than 10% of the set pressure at 10% allowable overpressure of the lowest-set relief valve tied into the header. When the superimposed back pressure is constant, the spring load may be reduced to compensate for the superimposed back pressure. WebWhen combined single-flare header size is greater than 80 in.–100 in. with a backpressure of 1.75 barg (approximately 50% of 3.5 barg), it is generally economical to segregate …
WebSep 16, 2003 · This parameter is often used as guiding criteria for design in fluid flow. The higher the number then you can expect higher pressure loss, something else you would want to avoid in a flare header. The TEMA standards use this parameter as a guide to select nozzle sizes for heat exchangers and when to use impingement protection.
