New API Standard provides comprehensive information on flares

The mechanical aspects for safe design and operation of flaring systems are defined for the first time publicly

Schwartz, R., John Zink Co. LLC

Hydrocarbon processing facilities traditionally depend on a single flare system and flare burner for safe, efficient disposal of relief or waste gases. Consequently, optimal processing performance must be combined with a service life that is compatible with current long turnaround cycles. The prime public information source for flare system design is the American Petroleum Institute (API) Recommended Practice 521 ?Guide for Pressure-Relieving and Depressuring Systems,? which addresses flare system design criteria. However, this standard does not provide guidance for mechanical details for such units. Responding to an initiative from within its membership, the API Committee on
