Description

This American National Standard specifies requirements and provides guidance for the selection, design, specification, operation, and maintenance of flares and related combustion and mechanical components used in pressure-relieving and vapor-depressurizing systems for petroleum, petrochemical and natural gas industries. While this standard is primarily intended for onshore facilities, guidance related to offshore applications is included. Annexes A through D provide further guidance and best practices for the selection, specification and mechanical details for flares and on the design, operation and maintenance of flare combustion and related equipment. Annex E explains how to use the data sheets provided in Annex F; it is intended that these data sheets be used to communicate and record design information.
