82 Management of Nitrogen Blanketing

Nitrogen blanketing, also known as nitrogen padding or tank blanketing, is a process in which nitrogen gas is introduced into the headspace of a liquid storage tanks or containers to create a controlled, inert atmosphere. The primary purpose is to displace oxygen and moisture from the container, preventing oxidation, degradation, or combustion of sensitive materials inside. This technique is commonly employed in industries where the quality and safety of stored materials, such as petroluem prodcuts, chemicals, pharmaceuticals, food products and othert flamable producta. Nitrogen blanketing helps maintain product integrity and safety by minimizing the presence of oxygen, which could otherwise lead to undesirable chemical reactions or degradation. The application of nitrogen blanketing involves introducing nitrogen into the storage tank at a controlled rate to displace the air and achieve the desired inert atmosphere. Monitoring systems for oxygen levels and pressure are commonly employed to ensure that the nitrogen blanketing process is effective and maintained within safe limits. Nitrogen blanketing is a critical safety measure in the oil and gas industry, playing a vital role in preventing accidents and preserving the integrity of storage systems for flammable petroleum products.
