Known as nitrogen purging, is a process where nitrogen gas is introduced into the tank to displace oxygen and other vapors, creating an inert atmosphere. This is done to prevent contamination and ensure safety when transporting or storing chemicals, especially those that are reactive or hazardous. 

Why nitrogen purging is important?

#Preventing Reactions:

Many chemicals react with oxygen or moisture. Nitrogen purging creates a barrier, preventing these unwanted reactions during transport or storage.

#Preventing Contamination:

Displacing residual vapors from previous cargo with nitrogen helps prevent contamination of the new product being loaded.

#Safety:

Reducing the oxygen content in the tank minimizes the risk of fire, explosions, or other dangerous chemical reactions.

#Compliance:

Nitrogen purging helps ensure compliance with safety regulations for handling and transporting hazardous materials. 

How it works?

1. Initial Assessment:

The ISO tank is checked to ensure it’s structurally sound and free of any contaminants. 

2. Nitrogen Injection:

Nitrogen gas is introduced into the tank, usually through a dedicated connection, displacing the existing atmosphere. 

3. Purging Process:

The nitrogen flow is maintained until the oxygen content within the tank reaches a safe level, typically below 1%. 

4. Monitoring:

The pressure and oxygen levels are continuously monitored to ensure the purging process is effective. 

5. Final Check:
