Nitrogen Tank Blanketing in Minneapolis

Nitrogen is used for numerous purposes in the specialty gas industry. Aside from utilization in food and drug preparation, it is used in the maintenance of different (typically highly flammable liquid) substances. This process of preventative maintenance is named blanketing in the specialty gases industry.

In the majority of tank vessels there is headspace that, left empty, can begin the oxidation process for elements 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 sets nitrogen amounts. The valve adjusts to keep consistent 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.
