Abstract
A method for controlling the Btu content of a flare gas to combusted in a flare stack comprising a flare tip is provided. The method includes, introducing a first gas stream including nitrogen to be flared, the first gas stream having an initial Btu content, providing a supplemental fuel gas stream, and combining the first gas stream with the supplemental fuel gas stream, thereby obtaining a flare gas stream having a final Btu content measured at the flare tip.
