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 Pressure (gauge pressure) Pressure for which the value is equal to the algebraic difference between the absolute pressure and the atmospheric pressure. , vacuum Vacuum 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 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 state-of-the-art 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. for these challenging applications, managing risks and ensuring reliable tank breathing, minimizing vapor release, and preventing flame transmission.
