Nitrogen Tank Blanketing in Southern California

Nitrogen is used for various purposes in the specialty gas industry. Other than being used in food and drug preparation, it is used in the preservation of various (typically highly flammable liquid) substances. This technique of preventative maintenance is named blanketing in the specialty gases industry.

In the majority of tank vessels there is headspace that, left unfilled, can commence the oxidation process for elements that are liable to this occurrence. In order to maintain these properties 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 fills the tank, a valve control system on the tank controls nitrogen quantities. The valve adjusts to keep consistent positive pressure in the headspace of the tank. While the tank is emptying, there will be a significant increase of nitrogen to account for the empty space.
