Nitrogen Tank Blanketing in Springfield04/25/2019Nitrogen is used for many purposes in the specialty gas industry. Other than being used in food and drug preparation, it is used in the preservation of various (typically highly flammable liquid) substances. This method 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 materials that are susceptible to this occurrence. To keep these elements 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 inhabits the tank, a valve control system on the tank regulates nitrogen quantities. The valve regulates 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 compensate the empty space.
