Preventing Explosions: The Science Behind Flame Arrestors for Storage Tank Venting

Storage tanks are a vital part of many industries, from oil and gas extraction to the chemical industry. These tanks store flammable liquids that can pose a serious safety hazard if not properly managed. To prevent the buildup of hazardous fumes and protect workers and the environment, an efficient and well-designed ventilation system is essential. This is where flame arrestors come into play.

What Are Flame Arrestors?

In short, they are safety devices that prevent flames from spreading through pipes into storage tanks. They are designed to prevent the spread of flames, limiting damage and potential explosions that can occur in a storage tank. In essence, they are a type of passive safety system.

How Do Flame Arrestors Work When Venting Storage Tanks?

• Location: Flame arrestors are typically installed at the end of a vent pipe where flames or sparks could enter the storage tank.
• Mesh or Plate Design: There are two types of flame arrestors: mesh and plate. Mesh flame arrestors use a series of small metal wires to interrupt the flow of flames, while plate flame arrestors use a series of perforated plates to extinguish flames.
• Flame-Gas Barrier: The mesh or plate design of a flame arrestor creates a barrier between the flame and the flammable gas in the tank. This barrier interrupts the flame, preventing it from returning to the tank.
• Pressure Relief: In addition to extinguishing flames, flame arrestors can also relieve pressure on the storage tank. As hot gases are released through the vent pipe, the flame arrestor limits the pressure buildup to a safe level.

In short, flame arrestors play a critical role in venting storage tanks, preventing potential explosions, and protecting workers and the environment. These important safety devices are designed to prevent flames from spreading through pipes into storage tanks, providing reliable passive protection in industries where flammable liquids are stored. So the next time you see a storage tank, remember the important role flame arrestors play in keeping us safe.
