Abstract (en)
[origin: EP0384483A2] A process and apparatus for air rectification are described. Nitrogen (16) taken off from the process is warmed to a medium temperature, partially passed out (30) of the main heat exchanger (17) and expanded (31) producing energy. The expanded gas (32) releases its cold in the main heat exchanger (17) to air (1) to be separated and is re-compressed (33, 36). <IMAGE>
