Abstract

The nitrogen rich stream produced by a cryogenic air separation unit is heated indirectly by burning low grade fuel gas in a burner (20) at low pressure and the heated, elevated pressure nitrogen rich stream produced is expanded in a turbine (24) to obtain useful work prior to the discharge of the nitrogen rich stream at an outlet (28).
