A staged flare design utilizes a smaller capacity flare to handle flaring requirement during normal operation, maintenance, and start-up cases; and a larger capacity flare to handle emergency flaring requirements.
Staged flare systems can include the following:

Maintaining effective cobustion efficiency and destruction efficiency are key to minimising methane from flaring. This can be achieved through improving the mixing of flare gas and air to enable complete combustion and/or by only lighting the flare when required using ignition and pilot-light systems that avoid the risk of venting.
