Process for the production of nitrogen and oxygen
Patent
·
OSTI ID:6982858
A new French-developed air-separation process reduces energy consumption and investment costs by using LNG revaporization as an external refrigeration source. The LNG is used to produce liquid nitrogen so that the air-separation process produces oxygen and nitrogen in gaseous and liquid forms. The oxygen and nitrogen may be available at several pressure levels in the gaseous phase.
