Safety is a top priority in the oil & gas industry, and nitrogen plays an integral role. Pneumatech's on-site nitrogen generators are used in multiple onshore and offshore applications.
Nitrogen blanketing is a process that involves applying nitrogen to storage containers or tanks that contain hazardous chemicals that could explode if they come in contact with oxygen. This process creates a protective layer of nitrogen around the substance, and replaces any humid/moist air with dry nitrogen. This prolongs the life of the chemical or product, as well as diminishing any explosive or safety hazard associated with it.
Nitrogen purging is the process of using nitrogen gas to "flush" the oxygen out of tanks, containers or facilities. This is often used in the oil & gas industry for line clearing or line pigging to reduce the oxygen levels inside of a pipeline. This process also reduces the risk of an explosion in the piping that could be catastrophic.
Pressure in Reservoirs
Additionally, nitrogen is also used to hold pressure in reservoirs or tanks that have either been depleted of oxygen or have experienced reduced pressure overtime. Because nitrogen does not mix with oil and water, it can be used to move traces of hydrocarbons to a production well from an injection well.
Nitrogen is an essential element in the oil & gas industry used for purging, blanketing, maintaining pressure and many other applications. Pneumatech nitrogen generators have also been used in a biofuel plant to transport biofuel through the piping in the plant, as seen in the image below.
Many companies still purchase their nitrogen – even though generating oxygen on-site offers more advantages.
