What is the purpose of installing nitrogen pipelines in a methanol atmospheric floating roof tank area?

First, nitrogen is introduced to maintain a slight positive pressure inside the tank, preventing air from entering and causing oxidation of methanol； Second, nitrogen can be used for displacement during maintenance.

For tanks without a nitrogen seal, can introducing nitrogen during maintenance be sufficient to achieve proper purging and meet the maintenance standards?
