What are the functions of introducing nitrogen into the methanol tank?
The first reason for using nitrogen is for safety – to isolate the container from the atmosphere and prevent the formation of explosive mixtures. The second reason is to reduce evaporation, especially in summer; nitrogen is used for sealing purposes. Thirdly, nitrogen helps to protect the floating roof inside the tank, thereby reducing corrosion and other issues
It is mainly for safety, to prevent the formation of explosive mixtures.
Isolate from air to reduce evaporation! ! ! ! ! !
Was nitrogen introduced during shutdown?
As long as there is a hazardous substance in the tank and there is an adequate supply of nitrogen, the system remains operational; moreover, the valves should not be opened too wide – a slight positive pressure is sufficient, as otherwise it would be a waste. Additionally, the difference in density between nitrogen and air is very small, so the amount of gas that escapes is minimal
