Nitrogen is used for flushing the top space of tanks in refineries or tankers.

 If oil is removed from the reservoir, the oil level in the tank will drop. At the same time, the top space of the tank needs to be inert with N2. Avoid chemical reactions that can cause fires. When oil is stored in the tank, the slag is deposited at the bottom of the tank over time. To do this, the tank needs to be cleaned regularly. To avoid adverse reactions between the slag and the cleaner.
