Réduction des émissions de vapeur et exploitation sûre de l'installation

In closed containers or tanks, managing pressure is crucial. PROTEGO® Pressure and Vacuum Vacuum Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. Relief Valves ensure safe operations by releasing accumulated pressure and compensating for vacuum conditions.

Dans les conteneurs ou réservoirs fermés, la gestion de la pression est cruciale. Les soupapes de surpression et de dépression PROTEGO® garantissent la sécurité des opérations en évacuant la pression accumulée et en compensant les conditions de dépression. Conçues pour des processus tels que le chargement, le déchargement, le nettoyage à la vapeur et les effets thermiques, elles peuvent servir de soupapes de surpression, de soupapes de dépression ou de soupapes combinées.

Reconnues par des secteurs tels que le pétrole et le gaz, la chimie, la pharmacie et la bioénergie, les soupapes PROTEGO® garantissent sécurité et efficacité grâce à leur conception innovante et leurs performances supérieures.

Points forts des soupapes de reniflard PROTEGO®

Zéro émission grâce aux soupapes de reniflard PROTEGO®

L'étanchéité exceptionnelle des vannes PROTEGO® garantit une émission nulle à la pression de service du réservoir.

Grâce à la technologie de fabrication de pointe des vannes PROTEGO®, la pression de la cuve est maintenue jusqu'à la pression de tarage avec une étanchéité bien supérieure à la norme conventionnelle. Conformément à la norme PROTEGO® PS-001, les taux de fuite sont mesurés à 90 % de la pression de tarage. Ces essais garantissent que les vannes PROTEGO® dépassent les exigences les plus strictes en matière de taux de fuite des normes EPA, API2000 et EN ISO 28300.

Pour atteindre l'objectif de réduction des émissions, les purgeurs à ouverture totale PROTEGO® utilisent la technologie de surpression de 10 %. Cette technologie permet d'obtenir des plages de pression d'ouverture et de fermeture très courtes. Le purgeur n'a besoin que d'une surpression de 10 % au-dessus de la pression de tarage pour atteindre son plein rendement. La pression de la cuve est maintenue juste en dessous de la pression maximale admissible.
Les purgeurs PROTEGO® dotés de la technologie de levée totale à 10 % constituent un atout majeur pour la réduction des émissions et la sécurité de fonctionnement des installations de traitement.

PROTEGO® 10% Technology

The PROTEGO® valves demonstrated outstanding zero-emission performance and helped us achieve the environmental standards required for our site.
