Understanding the Difference Between Pressure Relief and Vacuum Relief Conservation Vents

Conservation vents are a key part of the safe operation and maintenance of storage tanks. These vents prevent damage to the tank due to pressure or vacuum build-up, ensuring the safety of the surrounding area. There are two types of conservation vents: pressure relief vents and vacuum relief vents. Although they may look similar, they serve completely different purposes. It is important to understand the differences between them to ensure that your tank is functioning properly.

Pressure Relief Vents

Pressure relief vents are used to relieve excess pressure that builds up in a storage tank. This can happen for a variety of reasons, including temperature fluctuations, chemical reactions, or changes in liquid levels. The pressure relief vent opens to release excess pressure and prevent the tank from rupturing or exploding. This is especially important for tanks used to store flammable or hazardous substances, as any sudden drop in pressure can lead to catastrophic accidents.

Vacuum Relief Vents

Vacuum relief vents prevent a vacuum or negative pressure from forming in the tank. When liquids are drained, a vacuum is created that can cause the tank to collapse. Vacuum vents open to allow air into the tank, equalizing pressure and preventing potential damage. They are most commonly used in tanks that store liquids prone to evaporation or in tanks that are frequently emptied.

When Pressure and Vacuum Relief Vents Work Together

While pressure and vacuum vents have different functions, in some cases they can work together to ensure optimal tank performance. For example, if the tank contains a liquid that is prone to evaporation, both a pressure relief vent and a vacuum relief vent may be installed to ensure proper pressure equalization within the tank.

Conclusion

In short, conservation vents are an essential part of storage tank systems. Although pressure and vacuum relief vents may seem similar, they serve different purposes and play a critical role in the safe operation and maintenance of storage tanks. Properly understanding the differences between these two types of vents is essential to ensuring the safety and integrity of the storage tank system.
