Nitrogen Tank Blanketing in Pittsburgh

Nitrogen 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 technique of preventative maintenance is named blanketing in the specialty gases industry.

For most tank containers there is headspace that, left void, can begin the oxidation process for substances that are prone to this occurrence. In order to maintain these properties 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 fills the tank, a valve control system on the tank sets 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 significant increase of nitrogen to compensate the empty space.
