Nitrogen Tank Blanketing in Denver04/25/2019Nitrogen is used for many purposes in the specialty gas industry. Other than being used in food and drug preparation, it is used in the maintenance of numerous (typically highly flammable liquid) substances. This technique of preventative maintenance is termed 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 occupies the tank, a valve control system on the tank adjusts nitrogen amounts. The valve adjusts 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.
