LGN Liquid Assist Nitrogen Gas Generators

The LGN series plants produce high purity gaseous nitrogen (400 – 1600 Nm³/hr) by cryogenic distillation of atmospheric air. The generator is a liquid assist type and features a compact and modular design.

The plant utilizes an air compressor to provide feed air that operates above the gas Nitrogen delivery pressure. A small amount of liquid Nitrogen is necessary to be added to the top tray of the distillation column to provide additional refrigeration required for the plant to make up for the cold box heat loss.
