The process and the device serve for air separation and steam generation in a combined system that comprises a steam system (10) and an air separation plant (9), wherein a feed air stream (1) is introduced into a multistage air compression system (101 , 102, 103) having n stages (n >= 3) and compressed to a first high pressure that is equal to the final pressure of the air compression system, and, at this final pressure, is introduced (8) into the air separation plant (9). An intercooler is arranged between an i-th stage (102) (1 <= i < n) and an i+1-th stage (103) of the air compression system; there, the feed air stream (4) is cooled in indirect heat exchange with a feed water stream (11).
