<p>In a process for operating an air separation unit, air to be separated in a cryogenic air separation unit is compressed in one of at least two compressors (MAC1, MAC2), purified, cooled and separated in the air separation unit (19) to produce a fluid product (21) and depending on the temperature of the feed air (3, 5), the degree of humidity of the feed air or the temperature of a cooling water stream (W1, W1', W2, W2'), one of the two compressors is used to provide compressed feed air for the air separation unit.</p> |
