Nitrogen Tank Blanketing in St. Louis04/25/2019Nitrogen is utilized for various purposes in the specialty gas industry. Other than being used in food and drug preparation, it is used in the preservation of various (typically highly flammable liquid) materials. This method of preventative maintenance is termed blanketing in the specialty gases industry. In the majority of tank vessels there is headspace that, left unfilled, can activate the oxidation process for elements that are prone to this occurrence. To keep these elements in their purest condition during transportation and storage, high purity, dry nitrogen is used to replace the air that typically inhabits the headspace in these tanks. To control the amount of nitrogen that fills 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 tank is emptying, there will be a substantial increase of nitrogen to compensate the empty space.
