Alternatives to flare gas recovery for sour refinery flare gas
For many sour gas streams present in a flare header, less expensive options than flare gas recovery may exist. The compressors, liquids management, downstream treating and other systems required for flare gas recovery (FGR) can be expensive to install and/or operate reliably. Some refineries allow the flaring of sweet gases.
