Typical Nitrogen Generation Plant

Nitrogen forms a critical component of the utility system as it is used for various applications in a LNG Plant. Nitrogen is mainly used for purging, blanketing, and as a seal gas for various compressors and pumps. The above figure depicts a typical Nitrogen Plant set up upstream and downstream of the Nitrogen Generator. The Nitrogen is distributed to various trains, or users via the Nitrogen Distribution Header. A secondary Nitrogen Generation system such as the Liquid Nitrogen Storage & Vaporization package or another Membrane Nitrogen Generator is generally used as a backup system.
