Nitrogen Tank Blanketing

Nitrogen is used for various purposes in the specialty gas industry. Aside from utilization in food and drug preparation, it is used in the preservation of various (typically highly flammable liquid) substances. This method of preventative maintenance is called blanketing in the specialty gases industry.

For most tank containers there is headspace that, left unfilled, can begin the oxidation process for substances that are prone to this occurrence. To keep these substances in their purest state during transportation and storage, high purity, dry nitrogen is used to replace the air that usually occupies the headspace in these tanks.

To control the amount of nitrogen that occupies the tank, a valve control system on the tank regulates nitrogen quantities. The valve adjusts to maintain constant positive pressure in the headspace of the tank. While the tank is emptying, there will be a significant increase of nitrogen to compensate the empty space.
