Special applications with polymerizing and crystalizing substances, heated media and vapors with particulate carry over need advanced protection beyond standard tank venting. Complex conditions involving pressure, vacuum Dépression Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. , vapor, and temperature require proven engineerd solutions which provide stable, responsive, and reliable systems for both normal operations and upset scenarios in potentially corrosive and errosive environments.

Polymerizing Substances

Storage tanks with polymerizing substances like styrene, acrylates, and monomers need coordinated protection due to vapor accumulation and pressure fluctuations, with explosion risks. PROTEGO® Systems provide state-of-the-art pressure and vacuum relief and explosion protection Protection antidéflagrante An explosion protection is a flame arrester that prevents flame propagation into plant sections to be protected during explosions. for these challenging applications, managing risks and ensuring reliable tank breathing, minimizing vapor release, and preventing flame transmission.

Protection of Storage Tanks 
for Bitumen

Bitumen storage requires continuous heating, which complicates venting and relief equipment. Elevated temperatures and pressure must be managed safely. ​

PROTEGO® solutions include heat jacketed Pressure Vacuum Relief Valves Soupape de surpression et dépression A pressure and vacuum relief valve is a pressure equalization valve for impermissible pressure and vacuum in a closed system. to prevent solidification of product droplets in the vapor stream, ensuring venting reliability. Heated in-line Detonation  Flame Arresters provide explosion protection compatible with high-temperature environments, allowing safe tank breathing and prolonged operation.
