Special Applications

Reliable Venting and Explosion Safeguards 

Special applications with polymerizing substances and heated media need advanced protection beyond standard tank venting. Complex conditions involving pressure, vacuum Vacuum Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. , vapor, and temperature require stable, responsive, and reliable systems for both normal operations and upset scenarios.

Polymerizing Substances

Storage tanks with polymerizing substances like styrene, acrylates, and monomers need coordinated protection due to vapor accumulation Accumulation Pressure increase over the MAWP of the vessel allowed during discharge through the pressure-relief device. and pressure fluctuations, with explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. risks. PROTEGO® Systems provide pressure and vacuum relief and explosion protection Explosion protection An explosion protection is a flame arrester that prevents flame propagation into plant sections to be protected during explosions. , managing risks and ensuring safe tank breathing, minimizing vapor release, and preventing flame transmission.
