Oil and Petrochemical Refineries
Nitrogen Use in Oil Refineries
(5- 3vol.% O2 residual)
Nitrogen is used to inert storage or process tanks as well as move product through pipelines at refineries. Nitrogen prevents hazardous or explosive environments..
Oil and petrochemical refineries are highly complex environments that require the use of numerous gases and chemicals to carry out various processes safely and efficiently. Nitrogen is one such gas that finds wide application in these facilities. Here are some of the ways in which nitrogen is used in oil and petrochemical refineries:
- Tank blanketing: Nitrogen is used to create an inert atmosphere inside storage tanks to prevent the formation of combustible mixtures. This is important for maintaining safe conditions during tank filling, liquid transfer, and storage.
- Pipeline purging: Before introducing a new product into a pipeline, it is necessary to ensure that the pipeline is free of any residual product or contaminants that could cause contamination or an unsafe reaction. Nitrogen is used for pipeline purging to remove air, moisture, and other impurities.
- Sparging: Refineries often use nitrogen for sparging operations, where nitrogen is introduced into liquids to displace oxygen and other gases. This helps to minimize the risk of oxidation and maintain product quality.
- Process cooling: Nitrogen is used as a coolant in a variety of refinery processes, such as cryogenic condensation and liquefaction, and cooling reactors and vessels.
