Nitrogen Tank Blanketing in Mexico04/25/2019Nitrogen is utilized for various 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) materials. This method of preventative maintenance is called blanketing in the specialty gases industry. For most tank containers there is headspace that, left unfilled, can activate the oxidation process for substances that are prone to this occurrence. To keep 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 inhabits the tank, a valve control system on the tank adjusts 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 account for the empty space.
