Alcohol Storage Tanks without Emergency Relief Venting

PROTEGO® combines pressure and vacuum relief with in-line detonation and check valve protection for safe venting of flammable vapors. Vapors are safely routed with end-of-line explosion protection to prevent flame propagation. For products like alcohols, end-of-line Flame Arresters Apagallamas Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. may be designed for endurance burning Endurance burning Stabilized burning for an unlimited time. , ensuring reliable performance and compliance with standards.

Protection of Roofed Spirit Receiver Vessels 

Roofed spirit receiver vessels are used to collect and temporarily store alcohol vapors and liquids during processing operations. Maintaining safety in these vessels is essential for product quality and operational continuity.

The protection concept shown utalizes a Detonation Flame Arrester (the location is not restricted) to provide robust protection. This solution supports secure spirit storage while helping safeguard facilities and personnel.

Deflagration Protection for Spirit Receiver Vessels

This application offers deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). flame protection for spirit receiver vessels handling flammable alcohol vapors. It's designed for piping geometry with an L/D ratio of 50 or less, preventing flame propagation back into the vessel and ensuring safer operation and compliance with alcohol storage standards.
