Petroleum, petrochemical and natural gas industries - Flare details for general refinery and petrochemical service (ISO/DIS 25457:2022)

ISO 25457:2008 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 vapour-depressurizing systems for petroleum, petrochemical and natural gas industries.
Although ISO 25457:2008 is primarily intended for new flares and related equipment, it can also be used in the evaluation of existing flare facilities.
Further guidance and best practices are provided for the selection, specification and mechanical details for flares and on the design, operation and maintenance of flare combustion and related equipment.
ISO 25457:2008 also includes a set of data sheets, together with instructions and guidelines, for use in communicating and recording design information.

Industries du pétrole, de la pétrochimie et du gaz naturel - Détails sur les torches d'usage général dans les raffineries et dans les usines pétrochimiques (ISO/DIS 25457:2022)

L'ISO 25457:2008 spécifie les exigences et fournit les lignes directrices pour le choix, la conception, les spécifications, le fonctionnement et la maintenance des torches et des composants mécaniques et de combustion associés utilisés dans les systèmes de dépressurisation et de protection contre les surpressions pour les industries du pétrole, de la pétrochimie et du gaz naturel.
Bien que l'ISO 25457:2008 soit avant tout destinée aux nouvelles torches et aux équipements associés, elle peut aussi être utilisée dans l'évaluation d'installations de torches existantes.
Des lignes directrices complémentaires et les meilleures pratiques sont donnée quant au choix, spécifications et détails d'ordre mécanique relatifs aux torches et sur la conception, le fonctionnement et la maintenance des équipements associés et de combustion des torches.
L'ISO 25457:2008 inclut également un ensemble de fiches techniques, conjointement aux instructions et lignes directrices; afin de les tiliser pour communiquer et enregistrer des informations de conception.
