Abstract

The present invention is a process and apparatus for the production of gaseous and liquid nitrogen, comprising a single column nitrogen generator, and at least two expansion turbines, one that expands a portion of the incoming feed air and one that expands the oxygen-enriched waste, both of which are configured to operate with independently adjustable discharge pressures and are warmed separately in the main heat exchanger, thereby utilizing the maximum available expansion ratio.
