Abstract (en)
[origin: EP2369280A2] The method involves conveying air to a heat exchanger (21), and cooling the air in the heat exchanger by heat exchange with liquefied cryogenic coolant e.g. liquid nitrogen. The cryogenic coolant is vaporized, and the air to be cooled is passed through an air drier (26) e.g. adsorber drier, membrane drier and coolant drier, before supplying the air to the heat exchanger. The coolant evaporated in the heat exchanger is used as an operating agent in the air drier, and the evaporated cryogenic coolant is released to an expansion machine (32). An independent claim is also included for a device for producing cryogenic gaseous or liquefied air comprising a heat exchanger with a surface for thermal contact of air with evaporated cryogenic coolant.
