Nitrogen Tank Blanketing

Nitrogen blanketing is a practice commonly used in the chemical and petroleum refining industries to reduce the hazards associated with flammable liquids. Blanketing, or padding, is a process of injecting nitrogen gas into the vapor space of a tank or vessel, thereby minimizing the risk of an explosion or fire by displacing the oxygen and explosive gases in the tank with the inert nitrogren.

Challenge: Tank blanketing with nitrogen is a common safety technique used throughout the world. However, without accurate measurement and control of the nitrogen, too much gas results in wasted money and possible tank or component damage and too little gas is ineffective. Further, due to fill level, temperature and pressure variations in tanks, mass flow measurement is a the preferred measurement to ensure accurate and repeatable nitrogen delivery.
