Nitrogen Tank Blanketing in Indianapolis04/25/2019Nitrogen is used for numerous purposes in the specialty gas industry. Other than being used in food and drug preparation, it is used in the maintenance of different (typically highly flammable liquid) substances. This technique of preventative maintenance is named blanketing in the specialty gases industry. For most tank cylinders there is headspace that, left unfilled, can activate the oxidation process for elements that are liable to this occurrence. In order to maintain these substances in their purest condition during transportation and storage, high purity, dry nitrogen is used to substitute the air that typically inhabits the headspace in these tanks. To restrain the amount of nitrogen that occupies the tank, a valve control system on the tank adjusts nitrogen quantities. The valve regulates to maintain constant positive pressure in the headspace of the tank. While the vessel is releasing its contents, there will be a substantial increase of nitrogen to compensate the empty space.
