<p>Device (A) for generating a product (B) by cryogenic resolution of a gas mixture (C), especially air. Device (A) for generating a product (B) by cryogenic resolution of a gas mixture (C), especially air, comprises: (A) a compressor (2) for (C); (B) a direct-contact cooler for precooling (C); (C) a purification unit for precooled (C); (D) a cryogenic part (7), including a main heat exchanger (8a) for cooling purified (C) to about its dew point and a distillation column (9a) for cryogenic fractionation of cooled (C); and (E) a coolant recycle line (61) to supply coolant to (3), where (61) includes an evaporative cooler (15) that cools coolant in direct heat exchange with a gas stream from (7). The new feature is that the ratio (R) of (a) the distance (d1) between (15) and (3) and (b) the distance (d2) between (15) and (8a) is at least 0.5, especially at least 1.</p> |
