Nitrogen Tank Blanketing in Fresno

Nitrogen is used for numerous 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 called blanketing in the specialty gases industry.

In the majority of tank vessels there is headspace that, left void, can activate the oxidation process for substances that are liable to this occurrence. In order to maintain 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 fills 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 considerable increase of nitrogen to compensate the empty space.
